Types of dental implants in Switzerland: materials, shapes and components

At first glance, all dental implants look alike: a small screw a few millimetres in diameter and about a centimetre long. Yet behind this simple appearance lie important differences in material, shape, surface, connection to the crown, length and diameter. These characteristics influence how the implant integrates with the bone, its stability, its aesthetic behaviour, the ease of future repairs and its cost. This page presents the different types of implants and components, the situations in which each is used, the criteria for choosing a brand, and price benchmarks in Switzerland, expressed as differences relative to Geneva.

Most dental implants are made of titanium, a material with a very long track record; zirconia implants, white and metal-free, are an alternative with a shorter track record. Implants differ in their shape (cylindrical or tapered), their surface (treated to promote integration), their connection to the abutment, their length and their diameter. Short, narrow or angled implants make it possible to avoid certain grafts. There are also special solutions for severely resorbed jaws. The choice depends on each patient's situation and the practitioner's experience; a well-documented, traceable brand whose parts will remain available is an important criterion. The course of treatment is detailed on our dental implantology page. Prices: dental implant prices in Switzerland.

Implant treatment involves several parts. The implant itself is the part placed in the bone. The abutment, screwed onto the implant, passes through the gum. The crown, bridge or prosthesis is attached to the abutment. A screw often connects the assembly. Some implants, known as one-piece implants, incorporate the abutment directly.

Dental implants are often presented as a single product, whereas there are many variants. This page aims to explain these differences, to help everyone understand their dentist's proposals and ask the right questions. It complements our page on dental implantology and our dental care guide.

This page can be read in full or browsed by topic: materials, shapes and surfaces, connections, dimensions, special solutions, abutments and crowns, removable prostheses, brands and traceability, choice according to the situation, maintenance and prices. For the course of treatment, from imaging to crown placement, our page on dental implantology provides detailed additional information.

The first modern implants were smooth-surfaced titanium cylinders or screws with an external connection. Over the decades, shapes have diversified, surfaces have been treated to speed up integration, internal and conical connections have become standard, and shorter, narrower or ceramic implants have appeared. Computer-aided design has transformed the manufacture of abutments and crowns.

Implants are manufactured by high-precision machining, after which their surface is treated, cleaned and sterilised. Manufacturing tolerances are measured in microns. This precision determines the fit of the components and long-term reliability.

Reputable manufacturers apply strict quality controls at every stage. Each implant is identified by a batch number, making it possible to trace its origin.

Long-term studies on surface-treated titanium implants show very high survival rates, often above ninety-five per cent at ten years in standard situations. Short implants give good results when properly indicated, with fewer graft-related complications. Zirconia implants show encouraging medium-term results, with a track record still being built. Mini-implants used to stabilise a denture have satisfactory results within their indication.

Study results depend on the patients included, the practitioners' experience and the length of follow-up. They show trends, but each situation remains individual.

A long track record shows how a system behaves over many years. For a treatment intended to last, it is an important selection criterion.

Innovations are numerous. Cautious practitioners adopt new developments once they have proven reliable, and reserve less documented solutions for specific situations, with the patient's informed consent.

Recent innovations in implantology concern surfaces, with treatments that speed up integration; materials, with stronger alloys and two-piece zirconia implants; design, with shapes suited to immediate placement; and digital technology, with custom-designed abutments and crowns, surgical guides and better planning.

New developments are often promising, but their track record is limited. For a treatment intended to last decades, practitioners favour innovations validated by studies. It is legitimate to ask what track record exists for a proposed product.

The future may bring even more active surfaces, implants better suited to difficult situations, better prevention of inflammation and even more precise planning. The principle of osseointegration will remain at the heart of implantology.

Most implants are two-piece: the implant and abutment are separate, making it possible to choose the most suitable abutment and change it if necessary. One-piece implants, common in zirconia, incorporate the abutment from placement; they avoid a junction but offer less flexibility for correcting the angle or height.

Titanium has been the reference material for dental implants for several decades. It is light, strong, does not corrode in the mouth and, above all, allows bone to fuse directly to its surface. Implants are made of commercially pure titanium of various grades, or of stronger titanium alloys. Titanium allergies are exceptional.

Titanium-zirconium alloy, developed in particular for narrow implants, offers greater strength than pure titanium while retaining excellent integration. It makes it possible to place thinner implants in narrow ridges, sometimes avoiding a graft.

Titanium has accumulated several decades of clinical studies on millions of implants. It tolerates mechanical stress well, allows a wide variety of shapes, dimensions and components, and offers great flexibility for correcting an axis or modifying an abutment. These advantages explain why it remains the default choice for most situations, including the most complex.

In most cases, the colour of titanium is not visible, because the gum is thick enough and the abutment can be zirconia. When the gum is very thin, a graft or a light-coloured abutment often solves the problem.

Zirconia is a very strong, white ceramic. Zirconia implants are a metal-free alternative. Their colour can be an aesthetic advantage when the gum is thin. Their integration with bone is good with modern surfaces, but their clinical track record is shorter than that of titanium, and the choice of components is more limited. They are more sensitive to certain mechanical stresses and require an appropriate technique.

Zirconia is chosen by some people who prefer to avoid metal, or in aesthetic situations where very thin gum tissue might let the grey of titanium show through. The dentist discusses the advantages and limitations in each situation.

The zirconia used for implants is a high-strength ceramic, stabilised to resist cracking. Its surface is treated to promote integration with bone. It has a low affinity for bacterial plaque and a colour close to that of teeth, making it an attractive option for aesthetic areas. However, it is stiffer and less tolerant of handling errors than titanium: drilling, placement and screwing require precise technique.

One-piece zirconia implants include the abutment from placement. They protrude from the gum during healing, which means they must be protected from forces. They are suitable for situations where the axis of the implant matches that of the future tooth well.

Two-piece zirconia implants, which are more recent, allow the abutment to be chosen after healing, as with titanium. They offer more flexibility, with a track record still being built.

Placing a zirconia implant follows the same main stages as placing a titanium implant, with a few particularities. Drilling must strictly follow the manufacturer's recommendations, as zirconia is less tolerant of excessive stress during screwing. For one-piece implants, the part protruding from the gum must be protected from forces during healing, sometimes with a splint. The choice of crown and its cementation follow specific rules.

Zirconia requires specific experience. It is useful to ask the practitioner how many zirconia implants they have placed and what results they observe.

Small-diameter zirconia implants are generally avoided in areas subject to strong forces, such as the molars in people who clench their teeth.

Zirconia may suit people who wish to avoid metal, those with very thin gums in an aesthetic area, and rare cases of allergy. Titanium is often still preferred for complex situations and full prostheses.

For most situations, the titanium implant, with the longest track record, remains the reference choice. Zirconia is an alternative for people who prefer to avoid metal or in certain aesthetic situations, accepting a shorter track record and more limited component options. Reinforced titanium alloys are suitable for narrow implants. The dentist helps weigh these factors according to the patient's situation and priorities.

When the materials are properly indicated and placed by an experienced practitioner, titanium and zirconia both give good results. What matters is that the choice is an informed one.

For any implant proposed, it is legitimate to ask what clinical track record exists and which studies support its use.

General health influences the choice of implant type less than the decision whether or not to place implants and the precautions to take. Some situations do, however, guide the choice: in a person whose bone has been weakened by certain treatments, the dentist may prefer limited procedures, short implants or a removable prosthesis; in a person who wishes to avoid metal, zirconia may be considered.

For people with particular conditions or treatments, the dentist may consult the GP before proposing a plan, in order to adapt the type of procedure and the precautions.

After radiotherapy of the head and neck, placing implants requires specialised care. Implants can nevertheless improve rehabilitation after certain cancers.

Reactions to titanium are very rare. People with a history of multiple metal allergies can discuss this with their dentist and, if necessary, with an allergist. Zirconia is then an option.

Biocompatibility refers to a material's ability to be well tolerated by the body. Titanium and zirconia are among the most biocompatible materials used in medicine. Titanium spontaneously forms a thin, stable and inert oxide layer on its surface, which promotes integration and protects against corrosion. Zirconia is a chemically stable ceramic.

Research is investigating the possible release of very fine titanium particles around implants, particularly in the presence of inflammation. Their possible role has not been clearly established. Follow-up and prevention of inflammation remain the best measures.

People who are allergic to certain metals, such as nickel, are generally not allergic to titanium. If in doubt, a discussion with the dentist and, if necessary, an allergist is useful.

Some people prefer to avoid metal for personal reasons. Zirconia makes it possible to meet this wish, with an understanding of its indications and limitations.

Modern implants are screw-shaped, with a cylindrical or tapered body and threads of varying depth. The shape influences stability at placement, ease of insertion and suitability for different types of bone.

Tapered implants, which more closely resemble a root, often offer better initial stability in soft bone and in extraction sockets. They are frequently used for implants placed on the day of extraction and for immediate loading.

The threads are the part of the implant that anchors in the bone. Their depth, pitch and shape influence stability and the distribution of forces. Deep, widely spaced threads improve anchorage in soft bone; fine, closely spaced threads suit dense bone. Some implants combine micro-threads at the neck with deeper threads towards the tip, to distribute forces better and preserve the bone around the neck.

The choice of threads follows from the system and the bone density. The dentist chooses the most suitable implant from within their system.

When the implant is placed on the day of extraction, the socket is wider than the implant and irregular in shape. Tapered implants with aggressive threads anchor better in the bone beyond the socket and offer high initial stability, which is needed for a possible immediate temporary tooth. The space between the implant and the wall is filled with a bone substitute.

In an extraction socket, the implant is not placed in the centre of the former root, but slightly towards the palate or tongue, to preserve the bone on the lip side and the gum. This position is planned on imaging.

Immediate loading requires high stability. Well-anchored tapered implants and systems that can measure this stability facilitate this approach.

During healing or before the final crown, temporaries are often used. On a single front implant, a resin temporary crown screwed onto a temporary abutment allows the gum to be shaped. For a full prosthesis, a temporary resin prosthesis is screwed onto the implants on the day of surgery or shortly afterwards. These temporaries are designed to be light and not to overload the implants during integration.

The temporary makes it possible to check aesthetics, speech, chewing and hygiene before the final restoration is made. Adjustments made to the temporary guide the laboratory.

With a temporary on an implant, hard and sticky foods should be avoided during the integration period, so as not to overload the implant.

Even with a suitable implant, immediate placement is not always possible: significant infection, a missing bone wall or insufficient bone beyond the socket require a waiting period.

Some implants have notches that allow them to cut their own thread as they are screwed in. They make placement easier in soft bone. In very dense bone, prior tapping may be carried out.

Bone quality varies between areas and between people. In very dense bone, implants with fine threads and appropriate drilling avoid excessive compression. In soft bone, tapered implants with deep threads and under-preparation of the site improve stability. The dentist adapts the type of implant and the technique to the density seen on imaging and felt during drilling.

Osteoporosis mainly affects the skeleton, and the jawbone is often less affected. Implants can be placed, with precautions related to any treatments. Choosing implants suited to soft bone can be helpful.

The dentist senses the density of the bone while drilling and can adapt the technique in real time, for example by choosing a wider implant or modifying the preparation.

The upper part of the implant, called the neck, can be smooth or treated, straight or flared. Its design influences the stability of the bone and gum around the implant. Some implants are designed to be placed at bone level, others slightly above, at gum level.

Bone-level implants are placed so that their neck is flush with the bone. The junction with the abutment lies beneath the gum, offering great freedom to shape the crown profile, particularly in aesthetic areas. Tissue-level implants have a polished neck that passes through the gum; the junction is located higher, away from the bone, which can simplify hygiene and limit the junction's influence on the bone. They are often used in posterior areas.

The choice depends on the area, the thickness of the gum and the practitioner's habits. In aesthetic areas, bone-level implants are often preferred.

Tissue-level implants are often placed in a single stage, with their neck protruding from the gum from placement, which avoids a second procedure to uncover them.

Thick gum tissue can hide the junction and the colour of the titanium; thin gum tissue may point towards other choices, such as a zirconia abutment or a graft.

The implant surface plays an essential role in integration. The first implants had a machined, relatively smooth surface. Modern implants have treated surfaces, made slightly rough at the microscopic level by sandblasting, acid etching or oxidation, which increases the contact area and promotes the attachment of bone cells. Some surfaces are made hydrophilic to speed up the early stages of healing.

Modern surfaces have made it possible to shorten healing times, often to two or three months in good-quality bone, compared with several months in the past. They also improve results in soft bone.

The time before the crown is placed depends partly on the type of implant and its surface, but mainly on the quality of the bone and the stability achieved. With modern surfaces, it is often six to twelve weeks in good-quality bone, longer in soft bone or after a graft. Zirconia implants generally follow similar or slightly longer timescales, depending on the manufacturer.

Some devices measure the stability of the implant using a small, painless vibration. The result helps the dentist decide when to place the crown.

Hydrophilic surfaces and good initial stability sometimes make it possible to shorten timescales. However, the dentist does not take risks with an insufficiently integrated implant.

One-piece zirconia implants protrude from the gum during healing; they must be protected from forces, sometimes with a splint, until they have integrated.

At the microscopic level, the surface of a modern implant has hollows and ridges a few microns in size, which increase the contact area and help bone cells attach. Sandblasting with particles followed by acid etching creates roughness at two levels. Some surfaces are stored in a solution to remain hydrophilic and chemically active until placement, which speeds up the early stages of integration.

In soft bone, such as at the back of the upper jaw, modern surfaces markedly improve results and allow shorter healing times than in the past.

The surface must remain perfectly clean until placement. Implants are sterile-packed and handled without direct contact with fingers.

At gum level, a smoother surface limits plaque accumulation, while the part in the bone remains rough for integration. Some implants combine both.

The upper part of the implant, in contact with the gum, is sometimes smoother to limit plaque accumulation. Designs vary between manufacturers.

A rough surface exposed to the mouth, for example after bone loss, retains more plaque and is harder to clean. This is one of the reasons why preserving the bone around the implant and regular follow-up are important.

Inflammation around implants can affect all types of implants. Its prevention relies mainly on hygiene, follow-up and crown design. Some type-related factors may play a role: an exposed rough surface retains more plaque; a cemented crown may leave cement beneath the gum; a junction close to the bone may promote slight bone loss. Zirconia implants appear to retain less plaque, but are not immune to inflammation.

When the rough surface of an implant is exposed after bone loss, treatment may include thorough cleaning, sometimes polishing of the exposed surface to reduce plaque accumulation, or bone regeneration where possible.

Some studies suggest a favourable tissue response around zirconia. The track record nevertheless remains more limited; hygiene and follow-up are just as important as with titanium.

Whatever the type of implant, prevention relies on the same principles: daily hygiene, hygiene sessions, check-ups, stopping smoking and treating periodontitis.

The connection is the way the abutment fits onto the implant. It influences the stability of the assembly, the seal against bacteria, resistance to forces and ease of placement. A distinction is made between external connections, where a small shape protrudes from the implant, and internal connections, where the abutment fits inside. Internal conical connections, very widespread today, provide a tight, stable fit.

Some systems use an abutment narrower than the implant neck. This offset, called platform switching, moves the junction away from the bone and is thought to help preserve the bone around the neck.

The connection between the implant and the abutment transmits chewing forces and must remain stable for years. External connections, with a small hexagonal shape on top of the implant, were the first to be used; they rely on the screw for stability. Internal connections place the fit inside the implant, which improves stability and reduces stress on the screw. Internal conical connections, with a tight friction fit, offer a very good seal and high resistance to micro-movements.

The internal conical connection relies on a cone fitting into a cone at a small angle. When the screw is tightened, the surfaces lock by friction, like a Morse taper in mechanics. This connection offers great stability, a very good seal against bacteria and high resistance to micro-movements. It is used by many modern systems, with variations between manufacturers.

The conical connection requires great precision in manufacture and placement. Original components guarantee this fit.

Thanks to friction locking, screw loosening is less frequent with conical connections than with external connections.

Indexing is the shape that prevents the abutment from rotating on the implant and allows it to be repositioned exactly. It is important for transferring the implant's position to the laboratory.

Each screw must be tightened with a precise force, measured with a torque wrench. Insufficient tightening promotes loosening; excessive tightening can damage the screw or the implant.

Screws connect the abutment to the implant or the crown directly to the implant. They are made of titanium or alloy, sometimes with a coating that helps achieve optimal tightening. They are tightened with a torque wrench to a precise value specific to each system. Over time, a screw may loosen or, rarely, break, particularly with grinding or a poorly adjusted crown. Replacing a screw is generally simple if the system is known.

Some manufacturers recommend using a new screw when the crown is finally fitted, as the screw used during try-ins may have deformed slightly.

When a screw breaks inside the implant, the dentist uses specific instruments to remove the fragment. In most cases, the implant can be kept.

During check-ups, the dentist checks the stability of the crowns. A crown that moves slightly often indicates a loose screw, which should be retightened promptly.

The position of the junction between the implant and the abutment relative to the bone can influence the stability of the bone around the neck. Modern designs aim to limit bone loss in this area.

Each implant system has its own connection. Abutments and screws must be compatible. This is why it is important to know the brand and model of your implant, so that parts can be repaired or replaced years later.

A well-fitting connection limits micro-movements between the abutment and the implant, which could loosen the screw or allow bacteria to seep in. Manufacturing quality is therefore essential.

Some complications are related to the type of implant or component. Narrow implants are more prone to fracture in areas subject to strong forces. Zirconia implants are more sensitive to bending stresses. Poorly fitting connections or non-compatible parts promote screw loosening. Mini-implants can become loose if overloaded.

Implant fracture is rare. It occurs mainly with narrow implants, with severe grinding or after bone loss around the neck. The fractured implant generally has to be removed and then replaced.

An abutment or crown screw may loosen, especially with external connections or with grinding. The dentist retightens it to the recommended torque or replaces it.

Choosing an implant suited to the forces, original components, a well-adjusted crown and a night guard in case of grinding prevents most of these complications.

A few simple measures protect implants and their components day to day: wearing a night guard if you grind your teeth, a mouthguard for contact sports, avoiding biting hard objects such as pens, fruit stones or ice cubes, and seeking prompt advice if a crown moves, the gum bleeds or there is unusual discomfort.

Athletes exposed to impacts should protect their implants and crowns. A custom-made mouthguard, designed with the restorations in mind, reduces the risk of fracture of the crown, abutment or screw. After an impact, even without pain, a check-up is advisable to verify the stability of the crown and the absence of cracks.

Many people clench their teeth during physical exertion. This clenching can overload implants and crowns. A suitable guard can be worn during training if necessary.

After an impact on an implant tooth, it is advisable to check the stability of the crown, look for a crack in the ceramic and check the implant with an X-ray if necessary. A well-integrated implant generally withstands impacts well, but the crown, abutment or screw may be damaged. Prompt treatment prevents a small problem from getting worse and, in the event of an accident, makes it possible to deal with the accident insurer with the necessary documents.

When an impact occurs in an accident, it is useful to take photos, note the circumstances and seek prompt advice. The dentist prepares a report that will be used for dealings with the insurer. The implant passport also makes it easier to identify the parts to be replaced. Keeping these documents together, with the X-rays and invoices, simplifies all subsequent procedures and allows consistent follow-up of the restoration over the years, whichever dentist provides care in the future. These simple precautions save time and avoid many difficulties on the day a repair becomes necessary, even several years after placement.

A mobile crown, a clicking noise when chewing, a gum that bleeds or discharges pus, pain or an unusual odour around an implant should prompt a visit without delay.

Implants come in different lengths, often from six to sixteen millimetres, and different diameters, from about three to six millimetres. The choice depends on the available bone, the tooth to be replaced and chewing forces. Molars often receive wider implants; lateral incisors and lower incisors, narrower implants.

To conclude this overview, here is a comparison of the main implant families according to several criteria. It helps to place each option, without replacing the practitioner's personalised advice.

A less versatile option is not a worse one: it meets a particular situation. The dentist chooses the family suited to each patient's case.

For the majority of situations, standard titanium remains the benchmark. The other families widen the possibilities when the bone, the space or preferences require it.

This table summarises the main choices to be made during implant treatment. The dentist combines them according to each situation.

Before committing, ask which components will be used and why, check that they are all listed in the quote, and make sure you receive an implant passport. These simple precautions make follow-up easier throughout the life of the implant.

This table gives general guidelines. The actual choice depends on each situation and the practitioner's experience.

Short implants make it possible to place an implant when bone height is limited, below the sinus or above the nerve, without a major graft. Recent studies show good results in many situations, with fewer procedures and lower costs than grafts. They require an appropriate surface and design.

Short implants were long considered less reliable. Modern surfaces and appropriate designs have changed this perception. Studies comparing short implants with longer implants placed after a graft show similar results, with fewer complications, less pain, shorter duration and lower cost for short implants. They are now a serious option below the sinus and above the nerve.

Short implants require good bone quality, a crown that is not too tall relative to the implant, and careful adjustment of the bite. They are often splinted together when there are several.

In very soft bone or with a very tall crown, short implants may be less suitable. The dentist assesses these parameters on imaging.

The choice between a short implant and a graft is discussed with the dentist, depending on the bone, the area and the patient's preferences.

The following situations are based on common cases; they do not describe real patients.

Marc, 50, an upper molar and a low sinus

Marc had lost an upper molar. Imaging showed only seven millimetres of bone below the sinus. Rather than a lateral sinus lift, the dentist suggested a short, wide implant with a slight crestal lift. Treatment took four months instead of ten.

Nadia, 34, an incisor with thin gums

Nadia needed to replace a central incisor. Her gum was thin. The dentist placed a titanium implant with a gum graft and a custom zirconia abutment. No grey shadow is visible.

Robert, 78, a lower denture and very thin bone

Robert had a very thin ridge in his lower jaw. A graft was not desirable. Four mini-implants were placed, and his denture was clipped onto them. He can eat again without difficulty.

A wish for a metal-free implant

A forty-five-year-old woman wished to avoid metal. After discussing the advantages and limitations, a two-piece zirconia implant was placed for a premolar, with a good result.

A severely resorbed jaw

A seventy-year-old man had lost almost all the bone in his upper jaw. Zygomatic implants, combined with conventional implants at the front, made a fixed prosthesis possible without a graft.

A part that could not be found

A man had an implant placed twenty years ago from a brand that no longer exists. The crown screw broke. The dentist had difficulty finding a compatible part. In the end, a solution adapted by the laboratory was needed.

These situations show that the type of implant and components is chosen according to each situation, and that traceability and parts availability matter in the long term.

A woman and a narrow implant

A twenty-five-year-old woman had no lateral incisor. The space was narrow. A narrow titanium-zirconium alloy implant was placed, avoiding a graft. The crown looks very natural.

A man and a custom abutment

A forty-year-old man had an implant on a canine with a slight axis defect. A custom abutment corrected the orientation and made a crown screwed from the back possible.

An elderly woman and a bar

A seventy-five-year-old woman who had difficulty fitting her denture onto individual attachments benefited from a bar on four implants. The prosthesis now seats more easily.

Patients appreciate their dentist explaining the choice of implant and components. Many discover the importance of the implant passport when they change dentist. Those who have needed replacement parts emphasise the value of a widely used brand.

Patients who have received explanations about the type of implant and components often take away that there is no single implant, but solutions suited to each situation; that the implant passport is a valuable document; that the brand matters for the future; and that the quality of the practitioner and the follow-up is at least as important as the implant itself.

The most common regrets concern the lack of an implant passport, which complicates repairs, or the choice of an uncommon system whose parts have become difficult to find. These situations are easy to avoid by asking the right questions from the outset.

Patients advise asking for the brand and model, keeping the implant passport safe, comparing quotes for the same components and not choosing on price alone.

A man and his angled implants

A sixty-year-old man with a very low sinus on both sides wanted a fixed upper prosthesis without a graft. Four implants, two of them angled at the back, allowed a temporary prosthesis on the same day, followed by a final zirconia prosthesis.

A woman and a zirconia implant

A thirty-eight-year-old woman with thin gum tissue over an incisor chose a zirconia implant. The aesthetic result is very satisfying, with no grey shadow.

A man and his mini-implants

An eighty-two-year-old man could no longer wear his lower denture. Four mini-implants placed in a short procedure enabled him to eat comfortably again.

This feedback shows the diversity of solutions available and the value of adapting the type of implant to each situation, rather than applying a one-size-fits-all solution.

A woman and her two systems

A woman had an old implant from one system and was due to receive a second. The dentist chose the same system, which made it possible to use the same instruments and components for both crowns.

A man and his bar

A sixty-eight-year-old man with reduced dexterity had difficulty clipping his prosthesis onto individual attachments. A bar made fitting easier.

A young woman and a custom abutment

A twenty-nine-year-old woman had an implant on an incisor with slightly irregular gum tissue. A custom abutment and a temporary crown made it possible to shape the gum before the final crown.

This feedback highlights the value of adapting components to each patient's abilities and needs, and of staying consistent in the choice of systems.

These testimonials show that well-chosen components make it possible to adapt treatment to each situation, and that traceability is of real practical use in the long term.

Narrow implants are suitable for small spaces, such as upper lateral incisors or lower incisors, and for thin ridges. Their mechanical strength is lower; they are reserved for areas where forces are moderate, or made from stronger alloys.

Narrow implants, about three millimetres in diameter, are used when the space between two teeth is small, as for an upper lateral incisor or a lower incisor, or when the bone ridge is thin. Stronger alloys, such as titanium-zirconium, have improved their reliability. They often make it possible to avoid a ridge-widening graft.

Narrow implants are less resistant to high forces. They are not suitable for molars and should be avoided in people who clench their teeth heavily, unless suitably protected.

For lateral incisors, a narrow implant leaves more bone around it, which promotes stable gums and better aesthetics.

A minimum space between the implant and the neighbouring roots is needed to preserve the bone. Narrow implants make it easier to respect this space in small areas.

Wide implants offer a larger contact surface and better resistance to the forces exerted on molars. They require a sufficiently wide ridge.

The choice of length and diameter results from several measurements on imaging: the bone height available down to the nerve or up to the sinus, the width of the ridge, the space between neighbouring roots and the vertical space to the opposing tooth. The dentist keeps safety margins: a few millimetres above the nerve, a thickness of bone around the implant, a distance from neighbouring teeth. They then choose the implant that offers the best contact surface within these limits.

The vertical space between the implant and the opposing tooth determines the height available for the abutment and crown. Too little makes the work difficult; too much requires a tall crown, which exerts more leverage on the implant.

Two neighbouring implants must be separated by a sufficient distance to preserve the bone between them and allow a papilla to form. This is particularly important at the front.

Wide implants, five millimetres in diameter or more, are used for molars, which bear the greatest chewing forces. They offer a larger contact surface with the bone and better mechanical strength. They are also used in a molar socket after extraction, to fill part of the space. They require a sufficiently wide ridge, with a thickness of bone around the implant.

Combining a short and wide implant is common below the sinus: the width partly compensates for the short length by increasing the contact surface with the bone.

To remain stable, the implant must be surrounded by a sufficient thickness of bone, particularly on the cheek side. An implant too wide for the ridge would risk bone loss on that wall.

Chewing forces on molars can be considerable, particularly in people who clench their teeth. A wide implant, a monolithic zirconia crown and a protective night guard form a suitable combination.

Mini-implants, less than about three millimetres in diameter, are sometimes used to stabilise a lower denture when the bone is very thin, particularly in elderly people. They are often one-piece, with a ball head onto which the denture clips. They are less strong than standard implants; several are needed. They are different from the mini-screws used temporarily in orthodontics.

Mini-implants are placed using a minimally invasive technique, often without opening the gum. Their ball-shaped head protrudes from the gum and receives the denture's caps. They can sometimes be loaded quickly. They are mainly suitable for the lower jaw, in elderly people whose bone is too thin for standard implants and who do not want a graft. Their limited strength means that a sufficient number must be placed and that they should not be used for fixed prostheses subject to strong forces.

Mini-implants are less strong and have less contact surface with the bone. They are more prone to loosening if overloaded. Follow-up is important.

When the bone allows, two standard implants are often preferred to stabilise a denture, because of their strength and track record. Mini-implants are a useful alternative when the bone is too thin and a graft is not wanted.

The heads of the mini-implants and the denture caps are cleaned every day. The caps are replaced when they lose their grip.

When the upper jaw is severely resorbed, very long implants can be anchored in the cheekbone, known as the zygoma. They make it possible to attach a prosthesis without a major bone graft. They require complex surgery, often under general anaesthesia, by highly experienced surgeons.

Zygomatic implants are often three to five centimetres long. They are placed from the back of the upper jaw, pass through or along the sinus and anchor in the very dense bone of the cheekbone. Combined with conventional implants at the front, or with other zygomatic implants, they make it possible to attach a full prosthesis, often on the same day, in people whose upper jaw is severely resorbed.

They avoid major bone grafts, sometimes taken from the hip, and allow a fixed prosthesis to be fitted quickly. They considerably shorten the treatment time.

Their placement is complex and carries specific risks relating to the sinus, the eye and facial structures. They are reserved for highly experienced teams, after meticulous planning.

Zygomatic implants require regular follow-up, in particular of the condition of the sinus and of the gum around the point where they emerge into the mouth.

For the back of the upper jaw, angled implants can be anchored in dense bone located behind the molars. They sometimes avoid a sinus lift. Their placement requires particular expertise.

Pterygoid implants are long implants placed at the very back of the upper jaw, at a steep angle, to anchor in very dense bone located behind the tuberosity. They make it possible to support the back of a prosthesis without a sinus lift. Their placement requires great experience, as the area is difficult to access and close to vascular structures.

Zygomatic, pterygoid and custom subperiosteal implants: these advanced solutions address difficult situations in which conventional techniques would require extensive grafts. They are reserved for specialised teams and carefully selected patients.

Modern subperiosteal implants are custom-made metal frameworks produced from imaging, placed on the bone and beneath the gum, with posts that pass through the gum. They remain a marginal solution for very specific cases, with a limited track record for recent versions.

Once used, implants placed on the bone beneath the gum have largely been abandoned in favour of implants screwed into the bone. Modern versions, custom-made by printing, are sometimes offered for very specific cases.

The abutment is the part that connects the implant to the crown. There are many types, standard or custom, straight or angled, in titanium, zirconia or a combination. The choice influences aesthetics, the fit of the crown and the health of the gum.

The abutment passes through the gum and forms the transition between the implant, buried in the bone, and the crown, visible in the mouth. Its profile influences the shape of the gum and ease of cleaning. A well-designed abutment creates a harmonious emergence profile, meaning the crown emerges from the gum in a way comparable to a natural tooth. Standard abutments have pre-set shapes; custom abutments are designed for each situation.

The emergence profile describes the way the crown emerges from the gum. A profile that is too wide compresses the gum and makes cleaning difficult; one that is too narrow leaves a gap that traps debris. The dentist and the laboratory design it with care.

The height of the gum above the implant influences the choice of abutment. Thick gum tissue can hide the junction; thin gum tissue calls for more aesthetic precautions.

The health and appearance of the gum around the implant depend partly on the type of implant and components. The neck profile, the shape of the abutment, its material and the position of the junction influence how the gum organises itself around the restoration. An abutment that stays in place, without being removed repeatedly, limits disturbance to the gum.

Zirconia, being light in colour, avoids the grey tint that can show through thin gum tissue. Tissues appear to adhere well to its surface.

Titanium is also very well tolerated by the gum. When the gum is thick, its colour is not visible.

After the crown is fitted, the gum continues to stabilise for a few months. Slight recession may occur, revealing a margin. With a screw-retained crown and a replaceable abutment, the restoration can be adjusted. In some cases, a gum graft improves the appearance. The dentist assesses the situation at check-ups.

The gum around an implant generally stabilises within six to twelve months of the crown being fitted. Final aesthetic decisions are often made after this period.

In visible areas, accepting a few months with a temporary often makes it possible to achieve a more stable and natural aesthetic result.

Some practitioners place the final abutment at the time of implant placement and never remove it, to limit disturbance to the gum and bone. This approach depends on the system and the situation.

A custom abutment is computer-designed from the impression to follow the contour of the gum and support the crown optimally. It improves aesthetics and makes hygiene easier, particularly for front teeth.

Computer-aided design and manufacturing have transformed the production of abutments and crowns. From a digital impression, the laboratory designs a custom abutment and a crown, then mills them from a block of titanium or zirconia. This digital workflow improves fit accuracy, reproducibility and aesthetics.

For the digital impression, a small part is screwed onto the implant. It allows the camera to record the position and orientation of the implant precisely.

Many ceramic crowns and abutments are bonded to a small titanium base, which provides a precise metal connection with the implant while retaining the aesthetics of the ceramic.

3D printing is used for surgical guides, models, temporaries and certain parts. It speeds up manufacturing and allows a high degree of customisation.

The white zirconia abutment prevents a grey tint from showing through thin gum tissue. It is often bonded to a small titanium base, which ensures a strong connection.

The crown attached to the implant can be made from different materials, and can be screw-retained or cemented. The choice depends on the area, the forces, aesthetics and ease of maintenance. Removable screw-retained crowns are often preferred today, as they avoid excess cement beneath the gum and make repairs easier.

Monolithic zirconia, milled from a single block, is very strong and well suited to back teeth, which are subject to strong forces. Layered zirconia, covered with a more translucent ceramic, offers better aesthetics for front teeth, with a slight risk of chipping of the surface ceramic. Reinforced glass-ceramics, bonded to a titanium base, combine aesthetics and precision. The choice depends on the area, the forces and aesthetic expectations.

Layered crowns can develop small chips in the surface ceramic, particularly in people who clench their teeth. Monolithic crowns reduce this risk.

The laboratory reproduces the shade of the neighbouring teeth. For front teeth, try-ins in the mouth and sometimes a meeting with the ceramist are useful.

A screw-retained crown can be replaced without touching the implant, for example after wear or a fracture, or to match the shade after the other teeth have been whitened.

An implant placed today can remain in place for decades. Over such a long period, the mouth changes: natural teeth may move, the gum may change, other teeth may be lost or treated. A well-chosen implant from a widely used system, with removable components, makes it possible to adapt the restoration to these changes: replacing a crown, modifying an abutment, incorporating the implant into a new prosthesis.

Two-piece implants and screw-retained crowns offer great flexibility for these adaptations. This is an important argument for young people.

When placing a first implant, the dentist can take possible future needs into account, for example by positioning the implant so that it can later be incorporated into a more extensive prosthesis.

A cemented crown is bonded to an abutment with cement. It has no access hole, but it is difficult to remove, and excess cement beneath the gum can cause inflammation. It is used when the axis of the implant does not allow favourable access to the screw.

A screw-retained crown is attached directly to the implant or to a multi-unit abutment by a screw, accessible through a small channel in the crown. This channel is sealed with a tooth-coloured material. This solution allows the crown to be removed for cleaning, repair or replacement, with no risk of residual cement beneath the gum. It requires the implant axis to allow discreet access to the screw, which planning and angled channels make easier.

On front teeth, the channel is preferably placed on the inner surface, where it is invisible. On back teeth, it is located on the chewing surface and sealed with composite.

If the screw of a screw-retained crown loosens, the channel simply has to be reopened, the screw retightened to the recommended torque and the channel resealed. The procedure is quick.

Several neighbouring teeth can be replaced by a bridge screwed onto two or more implants. This avoids placing one implant per tooth and distributes the forces. It requires careful cleaning under the units.

Fixed full prostheses are made of zirconia or of resin on a metal framework. Removable prostheses are made of resin, with artificial teeth, and incorporate the attachment caps.

When the implant is not perfectly aligned with the axis of the future tooth, for example to avoid a nerve or use the available bone, an angled abutment or an angled screw channel makes it possible to correct the orientation.

In some situations, implants are deliberately placed at an angle, to use the available bone and avoid the sinus or the nerve. This is the case in full-arch rehabilitations on four implants, where the back implants are angled. Angled abutments then make it possible to straighten the axis of the prosthesis.

For screw-retained full prostheses, multi-unit abutments are screwed onto each implant. They compensate for differences in angle and height, and receive the prosthesis. They remain in place when the prosthesis is unscrewed for maintenance.

Some systems allow the screw channel in the crown to be angled, so that its access is on the inner surface of the tooth rather than the visible surface. This improves the aesthetics of screw-retained crowns.

Digital planning makes it possible to plan the angle of each implant and the corresponding abutment. This anticipation simplifies the making of the prosthesis.

Removable implant-supported prostheses are held in place by attachments. Individual ball-type attachments are screwed onto each implant; the prosthesis contains caps that clip onto them. Bars connect several implants, and the prosthesis clips onto the bar. Magnetic attachments are less common. Each system has its advantages.

For a removable implant-supported prosthesis, the attachment provides retention. Individual attachments, screwed onto each implant, are the most widely used: simple, compact and easy to clean. Their plastic inserts come in several retention levels, which makes it possible to adjust the force needed to remove the prosthesis. Bars, which connect the implants, offer greater stability and distribute forces, but require more space and more careful cleaning.

Inserts come in different strengths. The dentist chooses the strength suited to the patient's dexterity: lower retention for someone who has difficulty removing their prosthesis, higher for a firmer hold.

For a removable prosthesis, the implants must be sufficiently parallel for the prosthesis to be inserted easily. Some attachments tolerate angle differences.

Attachments are cleaned every day with a brush. During check-ups, the dentist checks for wear and replaces the inserts if necessary.

Inserts, small plastic parts in the prosthesis, provide retention. They wear over time and are easily replaced, often every one to two years, during a check-up.

Daily maintenance is similar for all implants: brushing, interdental brushes, check-ups. There are a few particularities depending on the type of restoration. Screw-retained crowns can be removed for thorough cleaning. Bar-retained prostheses require cleaning under the bar. Individual attachments are easy to clean. Fixed full prostheses require specific tools and periodic removal.

Hygiene must be adapted to each type of restoration. Around a single crown, interdental brushes of the right size clean the spaces between the implant and the neighbouring teeth. Under an implant bridge, special floss or interdental brushes are passed under the units. Around individual attachments, a small brush is enough. Under a bar, interdental brushes and floss are needed. Under a fixed full prosthesis, interdental brushes, special floss and often a water flosser are used.

The hygienist knows the particularities of the different restorations and adapts their instruments and advice accordingly. Fixed full prostheses can be unscrewed for thorough cleaning.

After placement, the dentist or hygienist demonstrates the appropriate hygiene techniques. It is useful to practise them in front of them to check that they are effective.

Zirconia implants and abutments are cleaned in the same way as titanium. Their smooth surface at gum level retains little plaque, but hygiene remains essential.

The hygienist uses instruments suited to implants, which do not scratch the surface of the titanium or zirconia.

Implants often last a very long time. Crowns, attachment inserts and sometimes screws wear out and need to be replaced over the years. Parts availability is therefore essential.

In everyday life, most implants are soon forgotten once the crown is fitted. Removable implant-supported prostheses need to be taken out for cleaning and often at night; fixed prostheses stay in place. People with zirconia or titanium implants live in the same way. The differences mainly concern maintenance and check-ups.

Titanium implants can create artefacts on certain images of the head, without any danger. Zirconia implants create fewer. It is useful to mention them before a scan.

When travelling, it is useful to take your implant passport or a photo of it, to make any treatment by another dentist easier.

Fixed prostheses on four to six implants are screwed onto multi-unit abutments, which compensate for differences in angle between the implants. The dentist can unscrew them for maintenance.

To replace all the teeth in a jaw, several implant configurations are available, depending on the available bone and the type of prosthesis desired.

The upper jaw often requires more implants than the lower jaw, because the bone is softer and the sinus limits the height. For an upper removable prosthesis, four implants are often recommended, whereas two are frequently enough in the lower jaw.

The fixed full prosthesis is sometimes called a hybrid: it combines artificial teeth and artificial gum on a framework screwed onto the implants. It compensates for the loss of bone and gum.

Fixed full implant prostheses can be made from several materials. A metal or zirconia framework provides the structure; it is covered with resin and resin teeth, or with ceramic. Monolithic zirconia prostheses are very strong and aesthetic, but more expensive and more difficult to repair. Resin prostheses on a framework are more economical and easier to repair, but wear more.

The temporary prosthesis, often made of resin, is fitted on the day of surgery or shortly afterwards. It allows aesthetics, speech and chewing to be validated before the final prosthesis.

Resin teeth wear over the years and can be replaced. Zirconia prostheses wear very little.

The choice depends on the bone, the space, the budget, expectations in terms of comfort and the ability to carry out maintenance. The dentist presents the options during the assessment.

For a full jaw, the comparison between a removable and a fixed prosthesis involves several criteria. A removable prosthesis requires fewer implants, is easy to clean and costs less; it can be repaired simply. A fixed prosthesis feels close to natural teeth and is not removed, but requires more implants, specific maintenance and a larger budget.

Some people start with a removable implant prosthesis, then move to a fixed prosthesis by adding implants. This step-by-step approach is possible if it is planned from the outset.

When a lot of bone has been lost, the prosthesis must also replace the gum and support the lips. A removable prosthesis does this easily; a fixed prosthesis can do so with artificial gum.

The choice depends on the number and position of the implants, the space available, the patient's dexterity and their preferences. The dentist explains the options.

Removable implant prostheses, or implant-stabilised prostheses, combine the advantages of an easy-to-clean denture with the stability provided by implants. Depending on the number of implants, they may rest partly on the gum or entirely on the implants. With two implants in the lower jaw, the prosthesis also rests on the gum; with four implants and a bar, it can be entirely implant-supported and sometimes leave the palate uncovered.

Over time, the gum and bone beneath the prosthesis may change. A reline, which readjusts the inside of the prosthesis, is sometimes needed to maintain comfort and avoid overloading the implants.

For the upper jaw, a prosthesis on four implants with a bar can be made without covering the palate, which improves taste, speech and comfort.

There are a great many implant brands. Some, notably well-known European and Swiss manufacturers, have long-term clinical studies, controlled production, full traceability and a worldwide parts distribution network. Others, more recent or less documented, may be cheaper, but with a shorter track record and sometimes uncertain long-term parts availability.

Some manufacturers offer parts compatible with other brands' systems at a lower cost. Their fit may be less precise, which can lead to loosening or fractures. The original manufacturer's warranties may no longer apply.

In Switzerland, dental implants are medical devices subject to quality and traceability requirements. Each implant is identified by a batch number, recorded in the patient's file.

In Switzerland, dental implants and their components are medical devices. They must meet safety, performance and quality requirements, be manufactured using controlled processes and be traceable. The manufacturer documents its products, and professionals keep the batch numbers. These requirements protect patients and make it possible, if necessary, to trace a specific batch.

If a batch had a problem, traceability would make it possible to identify the patients concerned and inform them. This is one of the reasons batch numbers are systematically recorded.

Implants or components of uncertain origin, sold outside the usual channels, may not meet quality requirements. Reputable practitioners use compliant products purchased from reliable distributors.

Patients have the right to know the brand, model and batch number of their implant. This information appears on the implant passport.

Responsible practice in implantology relies on choosing documented, traceable systems, clear information about the type of implant and its components, no exaggerated promises about new products, and respect for the patient's preference where it is compatible with their safety. It also means explaining the limitations of each option.

Some offers put forward a brand, a material or a technology as their main selling point. The type of implant is important, but it is not enough: the quality of the assessment, planning, surgery, crown and follow-up matters at least as much. It is useful to keep a critical eye on commercial claims.

A transparent dentist states the brand and model used, the nature of the components and their cost, and provides an implant passport. They explain why they choose one option rather than another.

Before placement, the patient is informed of the type of implant, the components, the alternatives, the risks and the cost. They give their informed consent.

To find out about types of implants, it is best to rely on the dentist's explanations, publications from scientific societies and universities, and technical information from reputable manufacturers. Advertisements and forums should be read with caution, as they often highlight a single aspect, such as price or material.

Information about the implants placed, the X-rays and the file are covered by professional confidentiality. Patients can obtain a copy and pass it on to another dentist.

Patients have the right to know the nature of their implant and its components, to be informed of the alternatives and their costs, to consent or refuse, and to ask for a second opinion.

In the event of a disagreement about treatment or an invoice, it is advisable to discuss it first with the practitioner. Cantonal dental associations often have conciliation committees.

The implant passport, provided after placement, states the brand, model, diameter, length and position of each implant, as well as the components used. It is invaluable when changing dentist or in the event of a repair.

People who have had implants for a long time may need to replace a crown, a screw or an attachment. To do so, the implant system must be identified. The implant passport, the records of the dentist who placed it or an X-ray can help. For widely used systems, parts are generally available. For rare or discontinued systems, solutions adapted by the laboratory are sometimes possible, but more complex.

When a person no longer knows which system their implant belongs to, several clues help identify it. The X-ray shows the shape of the body, the threads and the connection. The records of the practice that placed the implant, if it still exists, may contain the brand and batch number. Some online tools and recognition databases compare X-ray images with known systems. Manufacturers can also help identify their implants.

When original parts are no longer available, the laboratory can sometimes produce a suitable restoration from compatible or custom-made components. These solutions require case-by-case assessment.

The best prevention is to keep your implant passport, keep a copy of your records and choose a widely used system from the outset.

When a part is no longer available, the laboratory can sometimes make a custom abutment from a compatible base. In other cases, replacing the implant must be considered.

When changing dentist, passing on the implant passport and X-rays makes treatment easier and avoids unnecessary examinations.

A broken crown or a loose screw can often be repaired without touching the implant, especially when the crown is screw-retained.

Switzerland is home to several internationally renowned implant manufacturers and has a long tradition of research in implantology. Swiss practitioners mainly use well-documented systems. Fees depend on the implant system, the components, the laboratory and the tariff point value. The differences given here are for a standard titanium implant with abutment and crown, as a percentage relative to Geneva.

Switzerland holds an important place in the history of implantology, with manufacturers of international standing, universities active in research and scientific societies that contribute to guidelines. This tradition is reflected in the widespread use of well-documented systems in Swiss practices, and in a culture of traceability and follow-up.

Several Swiss manufacturers produce titanium, alloy and zirconia implants that are used worldwide. Their systems are supported by clinical studies and a wide range of components.

University dental medicine centres, notably in Bern, Geneva, Basel and Zurich, take part in research on surfaces, short implants, zirconia and the prevention of inflammation around implants.

Most Swiss practices use one or two systems that they master. Zirconia implants and special solutions, such as zygomatic implants, are offered by specialised practitioners and centres.

Each implant system has its own instruments, drilling protocols, tightening torques and components. Practitioners train in the systems they use, often with the manufacturers and scientific societies. This is why most practices use one or two systems that they master perfectly, rather than a multitude of brands.

It is useful to ask the dentist which system they usually use and for how long. A practitioner who has worked with a system for a long time knows its strengths and limitations.

A patient who already has implants from one system can receive a new implant from another system. However, using the same system can simplify components and maintenance.

For advanced solutions, such as zygomatic or pterygoid implants, or two-piece zirconia implants, some practitioners have specialised. Your regular dentist can refer you to them.

The budget varies according to the type of implant and components: a zirconia implant, a custom abutment or a special solution such as zygomatic implants cost more. Our page dental implant prices in Switzerland details the fees.

The price of implant treatment depends partly on the type of implant and components. The implant itself represents only part of the total cost; the surgery, abutment, crown, laboratory and follow-up weigh more heavily. Choices that increase the cost are often justified by aesthetics, durability or avoiding a graft.

Beyond the initial cost, maintenance must be budgeted for: hygiene sessions and check-ups, periodic replacement of inserts in removable prostheses, possible retightening or replacement of screws and, after many years, renewal of the crown or prosthesis. Widely used systems make these procedures easier and limit their cost.

For the same implant, the budget varies according to the components. A titanium implant with a standard abutment and a screw-retained monolithic zirconia crown is the baseline. A custom abutment adds a moderate surcharge. A layered ceramic crown for a front tooth may cost more. A zirconia implant generally increases the cost. For a removable prosthesis, individual attachments are less expensive than a bar.

More expensive component choices are justified by aesthetics, ease of maintenance or durability. The dentist explains their benefits in each situation, to allow an informed choice.

Replacement parts for the major systems are available and their cost is known. For rare systems, cost and lead time may be higher.

An implant that is cheaper to place can lead to higher long-term costs if parts are hard to find or reliability is lower. It is useful to think in terms of the entire lifespan of the treatment.

To compare two quotes, check the implant brand, the type of abutment, the crown material, whether follow-up is included and whether an implant passport is provided. A cheaper quote may be based on less documented components.

An implant quote often lists several items relating to the components: the implant itself, with its brand and dimensions; the healing screw; the abutment, standard or custom; the crown and its material; the screws; and possibly the attachments or bar. Laboratory costs and fees are added. It is useful to check that every necessary item appears on the quote, to avoid surprises.

It is useful to ask the dentist the cost of alternatives, for example a standard rather than custom abutment, or a short implant rather than a graft, along with the advantages and limitations of each.

The initial quote does not generally include long-term maintenance. It is useful to ask for an estimate of the cost of annual check-ups and possible replacement of inserts.

An implant on holiday

A man lost the screw-retained crown of his implant while staying in another region. Thanks to the photo of his implant passport, a local dentist was able to identify the system and screw the crown back on.

Two quotes, two brands

A woman received two quotes: one with an implant from a major brand, the other with a lesser-known implant that was considerably cheaper. After discussion, she chose the documented brand, taking into account parts availability over twenty years.

A discussed choice of zirconia

A man wanted a zirconia implant for a molar because of his concerns about metal. The dentist explained the mechanical limitations in this area and the absence of a proven allergy. They agreed on a titanium implant with a zirconia crown.

These situations highlight the practical usefulness of the implant passport, the value of comparing quotes with the long term in mind, and the importance of an open dialogue about the choice of material.

A woman and a lower incisor

A fifty-year-old woman needed to replace a lower incisor. The space was very small. A narrow implant was placed, with a slim crown. The result is discreet.

A man and a bar

A seventy-year-old man had four implants in his upper jaw. A bar was chosen to stabilise his removable prosthesis, with an uncovered palate. He appreciates being able to taste food better.

A woman and a replaced crown

A woman had an implant crown that had become darker than her teeth after whitening. The screw-retained crown was replaced with a lighter one, without touching the implant.

These situations highlight the variety of components available and the value of screw-retained crowns for later adjustments.

A sixty-two-year-old patient who had worn an unstable lower denture for ten years wanted a more comfortable solution. The assessment showed a thin ridge but sufficient height at the front. The dentist presented three options: two standard implants with a small ridge-widening graft, two narrow implants in reinforced alloy without a graft, or four mini-implants. She chose the two narrow implants, with individual attachments. After three months, her denture was adapted to clip onto them. She now eats without discomfort and cares for her implants easily.

This journey shows the value of presenting several suitable options, with their advantages and limitations, so that the patient can make an informed choice.

Detailed fees can be found on our page dental implant prices in Switzerland and on the page dental implantology prices.

Implants are generally not covered by compulsory health insurance, whatever their type. Accident insurance may cover them after an accident. Supplementary insurance sometimes contributes, up to its ceiling.

Choosing the implant is not a matter of abstract preference: it follows from the assessment. The dentist takes into account the height and width of the bone, its density, the tooth to be replaced, the aesthetic zone, the stability needed for immediate loading, the patient's wishes and their own experience with a system. A practitioner who has mastered a given system often achieves better results than with a system they know less well.

The following table summarises common choices by situation. These are general guidelines; each case is assessed individually.

This table illustrates trends. The actual choice depends on the bone, the gum, health, the patient's wishes and the practitioner's experience.

To replace a central incisor, the dentist often chooses a standard-diameter tapered implant, positioned slightly towards the palate, with a custom abutment and a ceramic crown. If the gum is thin, a zirconia abutment or a gum graft is considered. For a lateral incisor, a narrow implant is common. The aim is a natural gum contour and a crown indistinguishable from the neighbouring teeth.

For a molar, the implant is often wide, sometimes short below the sinus, with a standard or custom abutment and a screw-retained monolithic zirconia crown. Strength and ease of maintenance take priority over aesthetics.

For a premolar, a standard-diameter implant is common, with a zirconia or ceramic crown, depending on how visible the tooth is when smiling.

To stabilise a lower denture, two standard implants placed at the front of the jaw, with individual attachments, are a simple and effective solution. When the bone is very thin, four mini-implants can be an alternative. For the upper jaw, four implants are often needed, with attachments or a bar.

For a fixed full prosthesis, four to six implants are placed, often with angled implants at the back. Multi-unit abutments receive the screw-retained prosthesis. In cases of severe resorption of the upper jaw, zygomatic implants can complete the set-up.

These choices are guidelines. The dentist adapts the plan to the bone, the gum, the bite and the patient's wishes.

To illustrate the decision-making process, here is the case of a fifty-eight-year-old who needs to replace an upper molar and a neighbouring premolar. The assessment shows a low sinus above the molar and adequate bone under the premolar. For the molar, the dentist proposes a short, wide implant with a slight crestal sinus lift, and for the premolar, a standard implant. Both implants belong to the same widely used system. After integration, two screw-retained monolithic zirconia crowns are fitted. An implant passport is provided.

The short implant avoided a more invasive lateral sinus lift. Using the same system for both implants simplifies the components. The screw-retained zirconia crowns are strong and removable.

The dentist had also presented the option of a lateral sinus lift with a longer implant. The patient chose the simpler option, aware of its advantages and limitations.

For a very elderly person, simple, easy-to-maintain solutions are preferred. For a young person, the dentist seeks to preserve the bone and gum in the long term. For a person who clenches their teeth, they choose strong implants and crowns, and provide a night guard.

Age influences certain choices. In young adults, who will keep their implants for decades, the dentist favours systems with a long track record, solutions that preserve bone and gum, and lasting aesthetics. In elderly people, they favour short procedures, short implants or mini-implants that avoid grafts, and prostheses that are easy to maintain.

In young adults, a screw-retained crown and a replaceable abutment make future adjustments easier, for example if the gum changes. Traceability is particularly important over such a long period.

In adolescents, the jaws continue to grow while the implant stays fixed: an implant placed too early would eventually look sunken compared with the neighbouring teeth. It is therefore necessary to wait until growth has finished, often around eighteen to twenty or even later, particularly for front teeth. In the meantime, temporary solutions maintain the space and aesthetics: a removable appliance, a bonded bridge or a tooth bonded to a retainer.

Congenitally missing teeth, such as lateral incisors or second premolars, are a common situation in young people. A plan agreed between the orthodontist and the dentist prepares the space and bone for future implants, which are often narrow.

During the waiting period, the bone in the toothless area may resorb. Keeping a baby tooth, when it is still present and healthy, or certain orthodontic techniques can help preserve it.

In seniors, removable prostheses on two implants or on mini-implants offer an excellent balance of comfort, simplicity and cost. They can be maintained by a carer if necessary.

In elderly people, the choice of implant type takes into account health, bone quality, dexterity and future independence. Short or narrow implants, which avoid grafts, and easy-to-clean removable prostheses are often preferred. The retention of the attachments is set so that the prosthesis is easy to remove. In the event of loss of independence, a removable prosthesis can be maintained by a relative or carer, and the attachments can even be removed to return to a simple denture if necessary.

Attachments screwed onto implants can be removed and replaced with cover screws, making it possible to return to a conventional denture if maintenance becomes impossible. This reversibility is an advantage for very elderly people.

For many seniors, stabilising a denture with two implants markedly improves eating, speech and confidence, for a moderate investment.

• Which brand and model of implant do you use?
• Why this diameter and length in my situation?
• Would a short or narrow implant avoid a graft?
• Is zirconia a relevant option for me?
• Which abutment are you planning?
• Will you give me an implant passport?
• Will parts be available in twenty years?

The type of implant is chosen in dialogue with the dentist. The patient can express their preferences, for example for a metal-free implant or to avoid a graft, and ask questions about the brand, track record and components. The dentist explains what is possible and advisable in the situation. A shared decision based on clear information is the best guarantee of satisfaction.

For complex treatment or an unusual choice, such as zygomatic implants, a second opinion can be useful. Imaging can be passed on.

The federal register of medical professions makes it possible to check that a dentist is authorised to practise and, where applicable, their specialist title.

• I know the brand and model proposed.
• I understand why these dimensions were chosen.
• Alternatives to a graft have been discussed.
• I know whether zirconia is relevant for me.
• I will receive an implant passport.
• The quote specifies the implant, abutment and crown.

Dental implants differ in their material, shape, surface, connection and dimensions. Titanium remains the benchmark; zirconia is a metal-free alternative. Short, narrow or angled implants sometimes avoid grafts, and special solutions exist for severely resorbed jaws. The choice follows from the assessment and the practitioner's experience. A documented, traceable brand ensures parts remain available over time. The full treatment journey is described on our dental implantology page.

• Titanium remains the benchmark, zirconia an alternative.
• Shape, surface and connection influence integration and stability.
• Short and narrow implants sometimes avoid grafts.
• Special solutions exist for severely resorbed jaws.
• The abutment and crown matter as much as the implant.
• The brand and traceability guarantee future repairs.
• The choice is based on the assessment and the practitioner's experience.

In summary, dental implants differ in their material, titanium or zirconia; their shape, cylindrical or tapered; their surface, treated to promote integration; their connection with the abutment; and their dimensions, from mini-implants to zygomatic implants. Abutments, standard or custom, and crowns, screw-retained or cemented, complete the system. The choice depends on the assessment, the area, the bone, the gum, the patient's wishes and the practitioner's experience. A documented brand and an implant passport guarantee long-term follow-up.

Ask for the brand and model, understand how the dimensions were chosen, discuss alternatives to grafts, consider zirconia along with its limitations, favour original components, keep your implant passport and follow the recommended maintenance: these few rules sum up the essentials.

For the full course of treatment, see our page on dental implantology. For aesthetics, our page on cosmetic dentistry. For an overview, our dental care guide.

Dental implants come in many variants of material, shape, surface, connection and dimensions. Titanium remains the reference with the longest track record, zirconia a metal-free alternative. Short, narrow and tilted implants often avoid grafts; mini-implants and zygomatic implants address specific situations. Abutments and crowns, standard or custom, complete the restoration. The choice, based on the assessment and the practitioner's experience, favours documented and traceable systems, which guarantee long-term follow-up.

Understanding the different types of implants helps you talk with your dentist, ask the right questions and make an informed choice. There is no ideal implant in absolute terms: there is the implant suited to your situation, placed by a practitioner who has mastered it and carefully maintained over the years.

Choosing an implant is not like picking an item from a catalogue. It is the result of a dialogue with a practitioner who knows your situation, your expectations and the systems they have mastered. The information on this page helps you understand that dialogue and ask the right questions: about the material, shape, dimensions, components, brand, track record and maintenance. With these reference points, you can take a full part in the decisions affecting your mouth for many years to come.

Behind their simple appearance, dental implants are high-precision devices available in many variants. Understanding these differences helps you talk with your dentist and ask the right questions. The best implant is the one suited to your situation, placed by a practitioner who has mastered it, and carefully maintained.

If you are considering an implant, ask your dentist which type of implant and which components they propose, why, and what the alternatives are. A full assessment and clear explanations are the best basis for an informed choice.

Materials, shapes, surfaces, connections, dimensions, abutments, brands and prices: answers to frequently asked questions.

Connections

What is a conical connection? A tight fit between abutment and implant.

Do parts from one brand fit another? No, except compatible components, to be used with caution.

Dimensions

What is a short implant? An implant of about six to eight millimetres.

Is a short implant reliable? Yes, in many situations.

What is a narrow implant? An implant about three millimetres in diameter.

Special solutions

What is a mini-implant? A very thin implant, mainly used to stabilise a denture.

What is a zygomatic implant? A long implant anchored in the cheekbone.

Abutments

What is an abutment? The part between the implant and the crown.

Why a zirconia abutment? For aesthetics where the gum is thin.

Brands

Does the brand matter? Yes, for track record, traceability and parts.

What is an implant passport? A document identifying each implant placed.

Titanium in detail

What is grade four titanium? A pure titanium widely used for implants.

Why titanium alloys? For greater mechanical strength.

What is titanium-zirconium alloy? A stronger alloy, useful for narrow implants.

Does titanium rust? No, it does not corrode in the mouth.

Can titanium be seen? Sometimes through a thin gum.

Zirconia in detail

Are zirconia implants one-piece? Often, but two-piece versions exist.

Is zirconia suitable for molars? In some cases, with precautions.

Can the angle of a zirconia implant be corrected? With more difficulty than with titanium.

Does zirconia retain less plaque? Some studies suggest so.

Who chooses zirconia? People wishing to avoid metal, or in certain aesthetic situations.

Shapes in detail

What is a self-tapping implant? An implant that creates its own thread.

Why deep threads? For better anchorage in soft bone.

What is the implant neck? Its upper part, in contact with the bone and gum.

Is a tissue-level implant different? Its neck protrudes slightly above the bone.

Surfaces in detail

Is a machined surface inferior? It integrates more slowly than treated surfaces.

Do modern surfaces shorten healing? Yes, often to two or three months.

What is a sandblasted, acid-etched surface? A surface roughened by sandblasting and acid.

Is an exposed surface a problem? It retains more plaque.

Connections in detail

What is an external hexagon? A historic connection on top of the implant.

What is platform switching? An abutment narrower than the neck, which is thought to preserve bone.

Can a screw loosen? Rarely, especially with a well-fitted connection.

Why do connections differ? Each manufacturer has its own system.

Dimensions in detail

What length for an implant? Often six to sixteen millimetres depending on the bone.

What diameter for a molar? Often a wide implant.

Does a short implant avoid a graft? Often, below the sinus or above the nerve.

Is a narrow implant less strong? Yes, it is reserved for areas with moderate forces.

Mini-implants

Are mini-implants durable? They can be, with limited indications.

How many mini-implants for a denture? Often four.

Do mini-implants avoid surgery? Placement is still minor surgery.

Are mini-implants used in orthodontics? Different mini-screws serve as temporary anchorage.

Complex solutions

Are zygomatic implants common? No, they are reserved for specific cases.

What is a pterygoid implant? A tilted implant anchored behind the upper molars.

Do subperiosteal implants still exist? Rarely, in custom-made versions.

Who places zygomatic implants? Highly experienced surgeons.

Abutments in detail

What is a custom abutment? An abutment designed to measure by computer.

What is an angled abutment? An abutment that corrects the axis of the implant.

Can the abutment be changed? Yes, on a two-piece implant.

Is the abutment visible? Normally not, it sits under the crown.

Attachments

What is an attachment? A part that holds a removable prosthesis on an implant.

Bar or studs? Studs are easier to clean, a bar is more stable.

Do the inserts need replacing? Yes, often every one to two years.

Brands in detail

Why are Swiss brands renowned? For their track record, research and quality.

Are cheap implants dangerous? They may have less track record and fewer parts available.

Are compatible parts reliable? Their fit may be less precise.

What if the brand no longer exists? Parts may become hard to find.

How do I find out the brand of my implant? From the implant passport or your records.

Choice

Who chooses the type of implant? The dentist, based on the assessment, in discussion with the patient.

Can I choose the brand? You can discuss it with your dentist.

Does the dentist use several brands? Often one or two they have mastered.

Does the practitioner's experience count? Yes, as much as the implant.

Situations

Which implant for an incisor? Often a narrow or standard tapered implant.

Which implant for an upper molar? Often a short one, or one placed after a sinus lift.

Which implant for a denture? Two to four implants or mini-implants.

Which implant for immediate placement? Often a tapered implant.

Which implant for a thin gum? Sometimes a zirconia abutment or implant.

Other questions

Can an implant break? Very rarely.

Can an implant be replaced with another type? Yes, after removal and healing.

Do implants set off security scanners? Generally not.

Is an MRI possible? Generally yes; you should mention it.

Do zirconia implants interfere with MRI? No.

Does the colour of the implant affect the crown? It can affect the shade of the gum.

Prices

Does a zirconia implant cost more? Often, yes.

How much does an implant cost in Switzerland? See our tables and our price page.

Does a custom abutment cost more? Yes, a moderate surcharge.

Are mini-implants cheaper? Less per implant, but more are needed.

Are zygomatic implants expensive? Yes, it is a very costly solution.

Does the brand affect the price? Partly.

Does the price vary by city? Slightly; see our tables.

Is there a charge for the implant passport? It is generally provided with the treatment.

Does a bar-retained prosthesis cost more? Often more than individual attachments.

Are inserts expensive to replace? Their cost is moderate.

Is a short implant cheaper? It often avoids the cost of a graft.

Does insurance cover a particular type of implant? No, coverage does not depend on the type.

Is a one-piece zirconia implant cheaper? Not necessarily; it depends on the system.

Are compatible components cheaper? Often, but with fit risks.

Do you pay for the abutment separately? It depends on the quote; check.

Does a wide implant cost more? Generally not significantly.
