Of all the procedures in modern dentistry, the dental implant is arguably the one that has most transformed the management of tooth loss. Before it, a missing tooth was either compensated for by a bridge that sacrificed two adjacent teeth, or by a removable denture more or less well tolerated. With it, the root itself is replaced, and the crown placed on top restores the function and appearance of a natural tooth, without touching the neighbouring teeth. This paradigm shift, opened up by the work of Per-Ingvar Br\u00e5nemark in the late 1960s, is today supported by more than five decades of clinical follow-up, and by some of the highest success rates in all of medicine.<\/p>\n
Yet despite its widespread use, the implant remains poorly understood. Many patients fear it, think it is reserved for extreme cases, or worry about a surgical procedure perceived as heavy. Conversely, some idealise it as a magical and definitive solution. The reality lies in the middle: an implant is a structured procedure, with precise indications, a rigorous protocol, and perfectly identified conditions for success. When these conditions are met, the result is durable and reliable. When they are not, failure is not inevitable, but a signal that needs to be read.<\/p>\n
This guide covers the entire subject: what an implant is, when it is indicated, how planning, surgery, and the prosthetic phase are carried out, modern protocols (immediate loading, all-on-4), maintenance, contraindications, costs, alternatives, and the misconceptions that are still widely circulating. The aim is not to make promises, but to make things clear.<\/p>\n
A dental implant is an artificial root<\/strong>, designed to replace the root of a missing tooth. It consists of three successive components:<\/p>\n Titanium has been used since the late 1960s. Its decisive property, discovered accidentally by Br\u00e5nemark, is osseointegration<\/strong>: within a few months, the jawbone fuses directly with the surface of the implant, with no intermediate tissue. This fusion gives the assembly a stability comparable to that of a natural root, and constitutes the cornerstone of the long-term reliability of implants.<\/p>\n The surfaces of modern implants are treated (controlled roughness, chemical treatments) to optimise bone adhesion. Five decades of refinement have produced implants whose clinical performance is now standardised at a very high level.<\/p>\n More recent, the zirconia option (high-performance ceramic) has spread for specific indications: patients sensitised to metals, aesthetic requirements with thin gums where titanium showing through at the collar would pose a problem, or simply a preference for a metal-free solution. The clinical follow-up of zirconia is shorter than that of titanium, but the published ten-year results are solid.<\/p>\n The indications for implants cover a wide range. The main situations:<\/p>\n Loss of a single tooth.<\/strong> Following an extraction, trauma, fracture, or congenital absence. This is the most frequent case.<\/p>\n Loss of several teeth.<\/strong> Several implants can be placed, or an implant-supported bridge can rest on two or three implants to replace a series of adjacent teeth.<\/p>\n Complete edentulism of an arch.<\/strong> Solutions such as all-on-4<\/strong> or all-on-6<\/strong>: 4 to 6 strategically distributed implants support a complete fixed prosthesis. The classic removable denture can also be stabilised by 2 to 4 implants, which avoids the usual retention problems.<\/p>\n Alternative to the traditional bridge.<\/strong> When the aim is to avoid grinding down two healthy adjacent teeth to serve as supports, the implant offers a more conservative solution.<\/p>\n Immediate post-extraction placement.<\/strong> In certain favourable cases, the implant can be placed in the same session as the extraction of a non-restorable tooth, without waiting for bone healing. This protocol requires rigorous selection but reduces the overall timeline.<\/p>\n Restoration of a poorly tolerated removable denture.<\/strong> A patient who has worn a complete removable denture for years can consider switching to an implant-stabilised solution, with transformed chewing comfort.<\/p>\n The implant is today considered the reference solution<\/strong> for replacing one or more missing teeth, provided that anatomical, medical and hygiene conditions allow it.<\/p>\n No implant is placed without a structured assessment. This step is as important as the surgery itself.<\/p>\n Clinical examination.<\/strong> The practitioner assesses the condition of the adjacent teeth, the health of the gums, the quality of the periodontium, the occlusion, the possible presence of bruxism, and discusses the patient’s medical history.<\/p>\n Panoramic imaging.<\/strong> A panoramic X-ray gives an overview of the arches, identifies the anatomical structures (sinuses, inferior alveolar nerve), and locates the elements to be avoided.<\/p>\n 3D cone beam imaging (CBCT).<\/strong> This is now a standard for implant placement. The CBCT scanner (cone beam computed tomography) provides a precise 3D image of the available bone, its density, the path of the nerves, and the position of the sinuses. This imaging allows the implant to be planned in advance<\/strong>, in dedicated software, before even entering the surgical site.<\/p>\n Study models and digital impressions.<\/strong> Coupled with the scanner, they allow combined bone + existing teeth planning, essential for precise placement and an anticipated prosthetic result.<\/p>\n Surgical guide.<\/strong> From this 3D planning, a resin-printed guide can be manufactured. This guide, placed in the mouth during surgery, directs the drill with millimetre precision to the planned position. Guided surgery<\/strong> is gradually becoming the norm in equipped practices, particularly for aesthetic zones or complex cases.<\/p>\n This digital planning profoundly changes implant placement: what was once a procedure largely dependent on the practitioner’s experience and spatial sense has become a planned, simulable, and verifiable procedure before any incision is made.<\/p>\n The placement of a simple implant is a short, well-tolerated<\/strong> procedure, performed under local anaesthetic<\/strong> in the vast majority of cases. Its typical duration is between 30 and 60 minutes.<\/p>\n Preparation.<\/strong> Rigorous asepsis, setting up the operating field, local anaesthetic. For an anxious patient, conscious sedation (nitrous oxide, or anxiolytic premedication) may be offered. General anaesthetic is only exceptionally justified for the placement of a single implant.<\/p>\n Access to the site.<\/strong> Two approaches exist:<\/p>\n Calibrated drilling.<\/strong> A succession of drills of increasing diameter prepares the bone site. Each drill is calibrated to respect a precise dimension, planned in advance. Drilling is carried out under continuous irrigation to avoid any bone overheating that would compromise osseointegration.<\/p>\n Screwing in the implant.<\/strong> The implant is screwed into the bone with a controlled tightening torque. Sufficient primary stability is crucial: if the implant is not immediately stable, its osseointegration will be compromised.<\/p>\n Closure.<\/strong> Depending on the protocol chosen, the gum is closed with sutures (submerged healing) or left open with a transgingival healing screw.<\/p>\n Aftermath.<\/strong> Standard analgesics for the first 24 to 48 hours, specific hygiene advice, soft food for a few days, follow-up at 7 or 10 days for suture removal. Post-operative pain is generally moderate and brief, comparable to that of a simple extraction.<\/p>\n For an implant to hold up over time, sufficient bone volume is required in height, width and density. However, the jawbone gradually resorbs<\/strong> after an extraction or tooth loss. A tooth missing for several years often leaves insufficient bone volume to receive an implant directly.<\/p>\n Several techniques make it possible to reconstruct the missing bone.<\/p>\n Guided bone regeneration (GBR).<\/strong> Filling biomaterial (synthetic bone, deproteinised bovine bone, sometimes autogenous bone harvested from the patient) is placed in the area to be augmented, covered with a protective membrane, and left to heal for several months. The newly created bone volume serves as a support for the subsequent implant.<\/p>\n Sinus lift (raising of the sinus floor).<\/strong> In the posterior maxilla, the floor of the maxillary sinus often drops too low after extraction of the molars. The sinus lift consists of gently lifting the membrane lining the sinus, and inserting a biomaterial to create the bone volume needed for implant placement. A common, reliable procedure, but one that extends the overall treatment time by several months.<\/p>\n Block grafts.<\/strong> In significant bone defects, a block of bone may be harvested from the patient (mandible, ramus, or even iliac area for very large defects) and fixed to the area to be reconstructed. A heavier technique, reserved for specific cases, declining since the improvement of biomaterials.<\/p>\n Bone expansion.<\/strong> For thin but sufficiently high bone ridges, expansion techniques make it possible to gradually widen the bone in order to insert an implant.<\/p>\n These preparatory steps add time (often 4 to 9 months between the graft and the actual placement of the implant) but determine the quality of the final result. A serious practice never places an implant on insufficient bone volume on the bet that “it might hold”.<\/p>\n Two variants have markedly shortened the traditional timelines of implant treatment.<\/p>\n Immediate post-extraction placement.<\/strong> When a tooth has to be extracted and the anatomical conditions are favourable (intact alveolus, no active infection, sufficient bone volume), the implant can be placed in the same session as the extraction. The overall treatment time is shortened, and post-extraction bone resorption is partially avoided. The indication must be made by an experienced practitioner, as not all extractions lend themselves to it.<\/p>\n Immediate loading.<\/strong> In certain favourable situations, a temporary crown can be placed on the implant on the day of surgery, without waiting for osseointegration. This allows the patient not to have a visible “gap” during the healing period. The temporary crown is placed in sub-occlusion (it does not touch the opposing tooth at full force) to avoid overloads that would compromise osseointegration. This approach is widely used in all-on-4 protocols, where the patient leaves the same day with a fixed temporary bridge on their new implants.<\/p>\n These protocols do not apply to all situations: bone volume, bone quality, primary stability of the implant, occlusion, and patient profile are all selection criteria. But when they are applicable, they transform the patient experience.<\/p>\n Once the implant is in place, the bone must fuse with its surface. This phase, called osseointegration<\/strong>, typically lasts three to six months<\/strong>. It is shorter in the lower jaw (denser bone), longer in the upper jaw or after a graft.<\/p>\n During this period, the implant is left in place, either covered by the gum (submerged healing) or with a healing screw visible in the mouth. A temporary crown or removable denture can fill the visible space.<\/p>\n It is the final stability<\/strong> of the implant that is measured at the end of this phase, by a mechanical test or by a resonance frequency measurement, before moving on to the prosthetic stage. An implant that has not osseointegrated correctly (primary failure) is removed and the area left to heal before possible reimplantation. This case remains a minority, around 1 to 3% according to the studies.<\/p>\n Once osseointegration is achieved, the prosthetic phase begins.<\/p>\n Abutment placement.<\/strong> The practitioner uncovers the head of the implant if it was buried, and screws on an intermediate abutment that will emerge from the gum.<\/p>\n Impression.<\/strong> Most often digital, sometimes conventional, it allows the laboratory to manufacture the final crown with precision.<\/p>\n Final crown.<\/strong> It is generally made of ceramic (zirconia, lithium disilicate), sometimes ceramic-metal. It is screwed<\/strong> to the abutment (a removable, repairable solution, favoured in modern dentistry) or cemented<\/strong> onto the abutment (a traditional solution, simpler but less flexible). The choice depends on the position of the tooth, the aesthetics, and the access.<\/p>\n Check-ups.<\/strong> A visit a few weeks later checks the gingival integration, the occlusion, and functional comfort.<\/p>\n For the patient, the final result is a tooth visually and functionally comparable to a natural tooth. The implant-supported crown is brushed, used and maintained like the adjacent teeth, with a few nuances dealt with in the maintenance section.<\/p>\n For patients who are edentulous or about to be on an entire arch, several protocols exist.<\/p>\n All-on-4.<\/strong> Four strategically distributed implants (two straight anterior, two tilted posterior) support a complete fixed prosthesis on the arch. Advantage: often insufficient posterior bone volume makes a graft unnecessary, since the tilted posterior implants bypass the bone-poor areas. The temporary bridge is placed in the same session, the final bridge after osseointegration.<\/p>\n All-on-6.<\/strong> Variant with six implants, which better distributes the masticatory forces. Chosen when bone volume allows and when the prosthesis’s expected longevity is prioritised.<\/p>\n Implant-stabilised removable denture.<\/strong> For patients who want an intermediate solution, two to four implants stabilise a complete removable denture that clips onto them. Chewing comfort is transformed compared to a classic denture, without reaching the stability of a fixed implant-supported bridge. A solution often chosen for financial or anatomical reasons.<\/p>\n These complete solutions have radically changed the management of edentulism. A patient who has worn a poorly tolerated complete denture for years can, within a few months, regain chewing, speech and confidence comparable to those of a natural dentition.<\/p>\n Dental implants are among the best-documented procedures in dentistry. The success rates reported at 10 years are in the range of 95 to 98%<\/strong> for implants placed in good conditions, on selected patients. Many implants placed 20 or 30 years ago are still functional.<\/p>\n But an implant is not immortal<\/strong>. Its longevity depends on several factors.<\/p>\n Hygiene.<\/strong> An implant does not get cavities, but the gum and bone surrounding it can become inflamed. Peri-implant mucositis<\/strong> is a superficial, reversible inflammation, comparable to gingivitis. Peri-implantitis<\/strong> is a deep involvement, with bone loss around the implant, much more difficult to treat and which can lead to the loss of the implant. Peri-implantitis is today the main long-term risk. It is prevented by rigorous hygiene and regular follow-up.<\/p>\n Professional follow-up.<\/strong> Patients with implants have a specific maintenance protocol: check-ups every 4 to 6 months depending on the profile, scaling with suitable instruments<\/strong> (Teflon, titanium or plastic curettes, never classic steel which would scratch the implant), assessment of peri-implant tissues, possible measurement of sulcus depth.<\/p>\n Risky habits.<\/strong> Smoking multiplies by two to three<\/strong> the risk of peri-implantitis and implant loss. Untreated bruxism exposes the prosthesis to fractures by overload. Poorly controlled diabetes delays healing and impairs the long-term prognosis.<\/p>\n Occlusion and the prosthesis.<\/strong> An implant does not “feel” like a natural tooth (absence of periodontal ligament). An occlusal overload goes unnoticed and can prematurely wear the prosthesis or loosen the abutment. Hence the importance of careful occlusal adjustment and regular check-ups.<\/p>\n Implants have their limits, which it is best to know.<\/p>\n Absolute or very relative contraindications<\/strong>:<\/p>\n Relative contraindications, to be assessed on a case-by-case basis<\/strong>:<\/p>\n Failures.<\/strong> They fall into two families:<\/p>\n In both cases, the implant can generally be removed without major sequelae, and reimplantation is possible after healing and possible reconstruction.<\/p>\n A refusal of an implant is never a refusal on principle, but always the observation that optimal conditions are not met. Many contraindications are temporary or modifiable.<\/p>\n Before choosing the implant, an honest comparison with the alternatives must have been made.<\/p>\n The traditional bridge.<\/strong> Advantage: no surgery, faster treatment (a few weeks), sometimes less expensive. Major drawback: two healthy adjacent teeth must be ground down to serve as abutments. If these teeth are themselves already crowned or damaged, the argument disappears, and the bridge becomes relevant again.<\/p>\n The bonded bridge (Maryland).<\/strong> A very conservative alternative (minimal preparation of a single tooth), but lower average longevity and limited indications (often the lateral incisors or canines).<\/p>\n The partial removable denture.<\/strong> The least expensive solution, but less comfort, aesthetics sometimes compromised by the clasps, and long-term stress on the abutment teeth. Relevant when the implant is contraindicated or financially out of reach.<\/p>\n Doing nothing.<\/strong> On certain posterior tooth losses, without functional or aesthetic discomfort, doing nothing is sometimes an option, provided one accepts the gradual bone resorption and the possible movement of the neighbouring teeth.<\/p>\n The crown on a preserved devitalised tooth.<\/strong> When the tooth can still be preserved by endodontic treatment and capped with a crown, this remains preferable to its extraction followed by implant placement. The motto remains: preserve as much as possible, replace when one can no longer preserve.<\/p>\n The cost of an implant varies significantly according to several factors, and there is no universal price. The main parameters:<\/p>\n In Switzerland, where professional qualification and material standards are among the highest in Europe, fees reflect this level of requirement. The quote from a serious practice is always detailed, step by step, and implicitly compares the cost to the expected durability. Over 15 to 20 years, an implant can prove more economical than a succession of bridges or dentures to be redone.<\/p>\n “Placement is very painful.”<\/strong><\/p>\n False in the vast majority of cases. The procedure is performed under local anaesthetic and remains comparable to that of a simple extraction. The aftermath is moderate, often less uncomfortable than that of a wisdom tooth extraction.<\/p>\n “The body rejects implants.”<\/strong><\/p>\n Titanium is not rejected in the immunological sense. The rare failures are due to a defect in osseointegration or peri-implantitis, not to allergic rejection. True allergies to titanium exist but are very rare.<\/p>\n “An implant lasts a lifetime.”<\/strong><\/p>\n An implant is durable, not immortal. The majority of implants last 20 to 30 years and more, but their longevity depends on hygiene, follow-up, and the absence of peri-implantitis. What most often fails in the long term is not the implants themselves, but the peri-implant tissues if maintenance lapses.<\/p>\n “Anyone can have an implant.”<\/strong><\/p>\n The indications are very broad, including in elderly patients. But each situation is to be discussed: bone volume, periodontal condition, general health, habits. A prior examination sets the framework individually.<\/p>\n “An implant replaces several teeth at once.”<\/strong><\/p>\n An implant replaces a root, therefore a tooth. For several teeth, several implants are necessary, or an implant-supported bridge that rests on 2 to 3 implants to replace a larger number of teeth.<\/p>\n “Implants set off airport security gates.”<\/strong><\/p>\n False. A titanium implant does not trigger airport detectors. It also poses no problem for modern MRIs (beyond the possible slight local artefact on the image).<\/p>\n Several situations justify a consultation to assess the appropriateness of an implant.<\/p>\n The dental implant is one of the most accomplished procedures in modern dentistry. Five decades of clinical follow-up, success rates above 95% at 10 years, standardised protocols, and digital planning that makes placement more precise than ever: no other solution replaces a missing tooth with as much reliability, durability and respect for the neighbouring teeth.<\/p>\n This does not mean that it is always the right answer. A tooth that can be preserved deserves to be, above all. Insufficient bone volume may require a prior graft. A non-stabilised periodontium must be treated before considering any implant. A patient who smokes can greatly improve their prognosis by reducing or stopping their consumption. None of these steps delay the implant solution: they make it reliable.<\/p>\n The right implant is not the quickest to place nor the cheapest. It is the one that, after a rigorous assessment, suitable planning and serious follow-up, will accompany the patient for decades without them having to think about it again. It is this level of requirement that distinguishes a structured implant practice from a mere commercial offering.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Clinique Chantepoulet explains everything about dental implants Of all the procedures in modern dentistry, the dental implant is arguably the one that has most transformed the management of tooth loss.
