The Complete Guide to Dental Implants (Domain Overview): from assessment and bone management through surgery to long-term maintenance

The Complete Guide to Dental Implants (Domain Overview): from assessment and bone management through surgery to long-term maintenance

A direct answer in under 60 words

In prospective studies followed for ≥20 years: implant survival rate 93.0%, mean marginal bone loss 1.11 mm, GRADE moderate [F1]; implants present complications and require strict maintenance [F26].

(The survival rate and marginal bone loss in the first half of that sentence come from a meta-analysis of prospective studies with ≥20 years of follow-up, GRADE moderate and with high heterogeneity, and are population-level estimates [F1]. The second half comes from a different source: a cost-effectiveness systematic review whose subjects were patients with severe periodontal disease (hopeless or questionable teeth), whose original sentence reads "implants are not permanent, present complications, and require strict maintenance"; it is a summary statement by the authors of that review, and must be read together with the context of its source [F26].)

Scope: This article is general oral-health education based on international literature. It does not address any country's insurance or regulations; consult local rules for care pathways and costs.

Where this article sits within the whole dental knowledge base

People searching for implants usually do not want to know "what an implant is"; they are stuck on one concrete question: will it hurt, do I need a bone graft, how soon can I eat, how many days of antibiotics, will I regret it. Each of those questions has its own canonical card answering it one at a time.

What this article handles is what lies between the cards: which links make up the whole course of care, what the physiological premise of each link is, which dimensions the literature offers when the decision to proceed is being made, and which situations count as signals to go back to a dentist. After reading it you will know which stage of the course your own question falls into, and can then move on to the corresponding canonical card (the list is in "The canonical cards of this domain" at the end).

Every medical statement in this article carries a fact-unit number [Fn], and can be traced item by item back to the fact ledger and source list at the end.

1. The domain map: an implant is a course of care, not a single operation

To help readers locate their own question, this article sets out the implant course of care in six stages: assessment; bone and soft-tissue conditions; surgery and bone management; waiting for osseointegration; loading of the prosthesis; long-term maintenance. These six stages are an editorial division made by this article, not a staging model proposed by any publication; the literature each stage rests on is listed in the right-hand column of the table below, so each stage can be traced back. This table gives a map, not a timetable: this article provides no treatment duration in days — that is an editorial decision made here, not a conclusion of any publication. What the literature on loading timing actually says (for example, a systematic review of prospective studies restricted to the edentulous maxilla, comparing immediate / early / delayed loading, found that its clinician-reported outcome measures followed no standardised approach, which made the reported outcomes highly heterogeneous [F22]) is dealt with in section 5; that observation sits at the level of research methodology, and does not amount to saying that clinical treatment timelines have no standard [F22].

What this table is saying is that the assessment side, the surgical side and the subsequent maintenance side each carry influencing factors recorded in the literature; the variables are not confined to the day of surgery [F4][F6][F26].

2. Anatomical and physiological background: why bone is the premise of an implant

2.1 What an endosseous implant is

The implants followed in the long-term prospective studies are titanium endosseous dental implants with cylindrical or conical screw-shaped designs [F1]. The term used in the literature is "implant-supported prosthesis" — the prosthesis above is supported by an implant placed in bone, and the consensus report accordingly takes "following the completion of the implant-supported prosthesis" as the point at which baseline records are established [F9]. Treatment protocols in implant dentistry usually include periods of waiting for the extraction socket to heal and for the implant to osseointegrate [F29]; the length of the course therefore does not depend on the time spent on the day of surgery alone [F29].

2.2 After a tooth is removed, the alveolar bone changes on its own

If nothing is done after extraction and the socket is left to heal unassisted, the ridge undergoes a quantifiable reduction. That meta-analysis pooled its estimates separately by "measurement method" and by "tooth site": assessed against one another with radiographic measurement, mean horizontal ridge reduction was 2.54 mm (95% CI 1.97–3.11) at non-molar sites and 3.61 mm (95% CI 3.24–3.98) at molar sites; with clinical measurement instead, horizontal reduction at non-molar sites was 2.73 mm (95% CI 2.36–3.11) [F11]. Clinical measurement and radiographic measurement are two different methods; the numbers cannot be substituted for one another, and comparisons of magnitude across methods do not hold [F11]. The conclusion of the same meta-analysis is that the amount of resorption varies with tooth type [F12].

This physiological fact is precisely the reason every later bone-management technique exists: the physiological bone resorption that follows tooth loss often leaves the available bone volume insufficient to place the implant in the position the restoration requires, which is why guided bone regeneration (GBR), sinus augmentation (SA) and alveolar ridge preservation (ARP) were developed [F14].

The question patients often ask — "can alveolar bone that has been lost grow back on its own" — is a question-level topic; see canonical card KM-DENTAL-39 (in production).

3. The assessment stage: which factors the literature marks as risks

3.1 Evidence strength is not treated alike across the board

An umbrella review covering 25 articles and 35 associations recalculated the effect sizes of the individual meta-analyses and graded the credibility of the evidence against established criteria [F3][F4][F5]. The point of that grading is this: things that are all called "risk factors" carry different credibility ratings even within the same review [F3][F4][F5].

• Among the meta-analyses of randomised controlled trials, the three associations that count as high-certainty evidence (GRADE) are: turned versus anodized surface treatment, submerged versus nonsubmerged healing, and bone augmentation with long implants versus short implants — in each of these three comparisons the former was associated with a higher risk of implant failure (the direction of the association must not be omitted) [F4].
• On the observational side, the association between smoking and implant failure was graded highly suggestive [F3].
• But the same review also states that among the meta-analyses of observational studies, not one association was graded convincing [F5].

The third point is the key one in this section: among the observational associations included in that review, none reached the highest credibility grade [F5]. Presenting any single one of those factors as decisive goes beyond what this publication can support [F5].

3.2 Failure does not have a single type of cause

In the prospective studies with more than 20 years of follow-up, out of 115 implant failures only 44 had their cause explicitly reported, and biological and mechanical causes were almost equally distributed [F2]. That means two things: long-term failure does not follow a single script of "inflamed gums", and the literature's own record of causes is incomplete [F2].

3.3 The decision framework: first ask "can this tooth still be kept"

In the setting of severe periodontal disease (hopeless or questionable teeth), a systematic review that included 12 publications addressed the cost-effectiveness question of "treating and maintaining the existing teeth" versus "extracting them and rebuilding with implants", and concluded that implant maintenance cost plus the cost of managing complications seems to surpass the cost of treating and maintaining periodontally compromised teeth [F25]. How that conclusion was arrived at needs to be stated plainly: of the 12 publications included in that review, 9 discussed the cost-effectiveness of preserving teeth and 3 discussed replacing periodontally compromised teeth with implants, so it is an indirect juxtaposition of two sets of literature rather than a head-to-head comparison in the same group of patients [F25]. This article therefore treats it only as evidence of a relative direction in cost; the cost structure itself varies with each locality's health-care system and fee arrangements, and no local cost inference is drawn here. The same review also cautions that implants present complications and require strict maintenance, and are not something that needs no further attention once fitted [F26].

The decision factors on the patient's side have also been studied: a qualitative study (grounded theory, 10 informants) noted that gatekeeping factors before treatment included cost and dental anxiety, and that trust in the dentist and dental team was crucial in the decision-making process [F27]. That study has a small sample and a qualitative design, and its evidence strength is lower than that of the systematic reviews above; this article therefore describes only "which factors were recorded" and infers no proportions from it [F27].

"Will I regret having an implant" is a question-level topic; this article does not lay out the individual types of experience, and refers you to canonical card KM-DENTAL-07 (in production).

4. Bone management: graft materials, techniques, and their respective complication profiles

4.1 Four categories of material, with no consensus on which is superior

The graft materials used for bone augmentation fall into four types: autogenous, allograft, xenograft and alloplastic [F13]. A systematic review including 53 studies states plainly that there is still no consensus on which type of material is superior, and that definitive conclusions were not possible because of the lack of high-quality evidence [F13].

"What is bone graft material" is a question-level topic; see canonical card KM-DENTAL-24 (in production).

4.2 Complication rates differ between techniques

A systematic review and meta-analysis including 100 studies quantified the pooled complication rates of maxillary bone augmentation techniques: sinus lift 7.98% (95% CI 2.78–15.55), guided bone regeneration 26.44% (95% CI 13.06–42.52), onlay grafting 19.61% (95% CI 13.94–25.99) and mixed techniques 20.10% (95% CI 13.92–27.09) [F15]. The same review notes that the more frequent complications were membrane or graft exposure, wound dehiscence and infection [F15].

The scope of these four figures has to be read along with the figures themselves: the analysis in that review is explicitly stated to concern "maxillary" bone augmentation techniques, and only the four techniques above were quantified — alveolar ridge preservation (ARP) is not in its analysis, and the figures cannot be extrapolated to bone augmentation in the mandible [F15].

Within that scope, what this set of figures means on the domain map is: maxillary bone augmentation is a stage of implant treatment that carries a risk profile of its own, and should not be regarded as a small add-on step to the surgery [F15].

One further piece of evidence has to be placed alongside those complication figures: in the umbrella review of section 3.1, bone augmentation with long implants versus short implants was associated with a higher risk of implant failure, and this counts as high-certainty evidence [F4]. In other words, bone augmentation appears in the literature under more than the single aspect of "making up the bone volume"; whether to carry it out, and with which technique, is a case-by-case judgement [F4][F14]. Actual treatment and its results vary from person to person and must be assessed by a dentist.

"Side effects of bone grafting" and post-operative severity judgement are question-level topics; see canonical card KM-DENTAL-28 (in production).

4.3 The two roads at the moment of extraction: immediate implant placement and alveolar ridge preservation

A systematic review and meta-analysis including 11 randomised controlled trials (353 patients in the immediate implant placement group, 348 in the alveolar ridge preservation group) compared the two approaches [F16]. The authors' conclusion is written as: within the limitations of that research, immediate implant placement can achieve esthetic outcomes and implant success comparable to alveolar ridge preservation, but there may be a higher incidence of postoperative complications and greater marginal bone alterations [F16].

The word "comparable" has to be read against the data: in that review, no statistically significant difference was observed for the esthetic score (PES, MD −0.05, 95% CI −0.52 to 0.43) or for implant failure (OR 2.09, 95% CI 0.98 to 4.44) [F16]. The point estimate for implant failure is 2.09-fold odds, the upper bound of the confidence interval is close to 4.5, and only 11 trials were included (353 patients in the immediate implant placement group, 348 in the alveolar ridge preservation group) — "not statistically significant" is not the same as "the two carry the same risk of failure", and this article therefore does not read it as proof that the failure risks of the two approaches are equivalent [F16]. As for postoperative complications, the results section of that review records a higher incidence in the immediate implant placement group (p < 0.05) [F16].

This is a textbook case of a decision with no single right answer, only trade-offs [F16]. Where the trade-off lands must be assessed by a dentist against the individual's conditions.

5. Surgery and osseointegration: why no standard answer can be given for the timeline

5.1 The research on loading timing lacks a common yardstick

A systematic review of prospective studies in patients with an edentulous maxilla, comparing immediate / early / delayed loading (5 studies included, zygomatic implants excluded), found that the clinician-reported outcome measures (ClinROs) followed no standardised approach, which created substantial heterogeneity in the outcomes the studies reported [F22]. The population restriction in that sentence must not be omitted: it describes the current state of measurement methods in 5 studies of the edentulous maxilla, not a general rule for the whole field of implant loading timing [F22].

5.2 "Sooner" does not mean the patient feels better about it

A different systematic review, including 40 articles representing 35 cohort studies, states that for implant-supported single or short-span reconstructions and for overdentures, there is no strong evidence to support that the timing of implant placement or loading influences patients' discomfort, their satisfaction with function or esthetics, or their overall satisfaction with treatment [F23]. The population restriction in that sentence must not be omitted — the same review goes on to record that for implant-supported full-arch fixed reconstructions, edentulous patients were more satisfied with immediate loading over the short term, but that this difference was no longer clear one year after treatment [F24]. In other words, the statement that "timing does not affect satisfaction" cannot be applied to the full-arch fixed reconstruction population [F23][F24].

Taking 5.1 and 5.2 together, three things can honestly be said in this section: treatment protocols usually include periods of waiting for the extraction socket to heal and for osseointegration [F29]; in the 5 prospective studies of loading timing in the edentulous maxilla, the clinician-reported outcome measures followed no standardised approach and the reported outcomes were highly heterogeneous [F22]; and in the population with single or short-span reconstructions and overdentures, there is no strong evidence that timing influences patient satisfaction [F23]. None of these three things is about "how long treatment ought to take" — what the literature answers here is how the research measured things and how patients felt, not a timetable. This article therefore provides no treatment duration in days; the length of an individual course must be judged by a dentist against the individual's conditions and the protocol chosen.

A step-by-step account of "the whole implant process" is in canonical card KM-DENTAL-25 (in production); "implant wound healing time" is in the supplementary card (implant wound healing, in production).

6. Post-operative care: the state of the evidence on pain control and medication controversies

6.1 Preemptive anti-inflammatory analgesia: it is done, but nothing is settled

A systematic review including 7 randomised controlled trials (589 patients in total) assessed the practice of preemptive analgesia with oral steroidal and nonsteroidal anti-inflammatory drugs [F17]. Its conclusion is that, owing to the heterogeneity between studies in protocols, drug regimens and outcome measures, no definitive conclusion could be drawn as to which preemptive agents are most effective and safest [F17].

This article therefore lists no drug names and no doses. Medication is a prescribing act, and must be judged by a dentist against the individual situation.

"Do implants hurt" is a question-level topic; see canonical card KM-DENTAL-47 (in production).

6.2 Antibiotic prophylaxis: two reviews differ in procedural scope, intervention definition and endpoint, and their conclusions differ accordingly

This is one of the long-standing points of disagreement in the implant field — the 4th EAO Consensus Conference 2015 listed "the role of antibiotic prophylaxis in dental implant surgery" alongside peri-implantitis, patient-reported outcome measures (PROMs) and health economics as key issues for the implant patient [F21].

Two meta-analyses that differ in inclusion scope, intervention definition and endpoint point in different directions [F18][F20]:

• A 2020 systematic review (14 publications included) assessed an intervention that was prophylactic antibiotics "given prior to" implant surgery as well as "given prior to and continued immediately following" it (PIFS) — not simply a single pre-operative regimen; among the implants included, 5,334 were placed with pre-operative antibiotics, 82 with antibiotics PIFS and 3,862 with no antibiotics [F20]. Its overall risk ratio was RR 0.47 (95% CI 0.39–0.58) and the number needed to treat (NNT) was 35, and the authors also note that a standardised regimen still needs to be established [F20]. The procedural scope of this one is limited to implant placement surgery and its endpoint is implant failure [F20].
• A 2026 systematic review and random-effects meta-analysis covering invasive dental procedures of all kinds, pooling approximately 1,950 participants, reports instead that antimicrobial prophylaxis did not demonstrate a statistically significant overall reduction in the primary pooled endpoint (MD −0.12, 95% CI −0.31 to 0.07; I² ≈ 99%) [F18]. Two definitions in this one must be read together with its conclusion: its "intervention" is systemic antibiotics and/or local antiseptic prophylaxis (not oral antibiotics alone — individual trials included chlorhexidine mouthwash), and its pooled endpoint is early procedure-related infectious outcomes and/or bacteremia-related endpoints — the latter being a surrogate measure, which is not the same thing as "implant failure" [F18].

The latter also notes that microbiological evidence indicates single-dose prophylaxis can promote short-term disturbance of the oral flora and selection of resistant strains [F19].

When these two are placed side by side, two things must be disclosed with them, or they will be read as two equally weighted "camps": first, the effect-size scales differ — the 2026 paper pools its primary endpoint as a mean difference (MD −0.12), whereas the 2020 paper pools implant failure as a risk ratio (RR 0.47), and the two figures can neither be converted into one another nor compared directly for magnitude [F18][F20]; second, they are indexed at different publication-type levels — on PubMed metadata retrieved for this article, the PublicationType of the 2026 paper is registered only as `Journal Article, Review`, while the 2020 paper is registered as `Journal Article, Meta-Analysis, Systematic Review` [F18][F20]. The authors of the 2026 paper also state themselves that their interpretation is constrained by extreme between-study heterogeneity [F18].

On that footing, the two cannot be treated as the positive and negative answers to one and the same question; the difference comes from three places rather than from which came first: procedural scope (the former limited to implant placement surgery [F20], the latter covering invasive dental procedures of all kinds including extractions [F18]), intervention definition (the former prophylactic antibiotics given pre-operatively and immediately post-operatively [F20], the latter systemic antibiotics and/or local antiseptics [F18]) and endpoint (the former implant failure [F20], the latter a pooled endpoint of early infection and/or bacteremia [F18]); the heterogeneity of the latter is also extreme (I² ≈ 99%), and it records that implant trials themselves had low event rates and did not consistently demonstrate a clinically meaningful superiority of routine prophylaxis [F18].

The honest formulation is: whether to take antibiotics, and for how many days, has not converged into a single consensus in the international literature; meta-analyses with different procedural scopes, different intervention definitions and different endpoints point in different directions [F18][F20][F21]. Any medication instruction follows the prescription of the treating dentist.

"How many days of antibiotics after an implant" is a question-level topic; see the supplementary card (implant antibiotics, in production).

6.3 Post-operative diet: the direct evidence available is limited

A small randomised comparative study (n=32) in hospitalised oral and maxillofacial surgery patients recorded a higher dietary intake figure in the nutritionally balanced soft blended diet group than in the full fluid diet group (63.2% vs. 51.0%) [F28]. The statistical disclosure here needs care: a p value was reported for diet satisfaction in the same passage (P<0.0001), but no statistical significance was reported for dietary intake, so it can only be read as a numerical difference and not as a demonstrated between-group difference [F28].

The limitations of that study must be stated plainly: the sample is small, the subjects are hospitalised oral and maxillofacial surgery patients rather than outpatient implant patients, and it is not a study of any beverage (coffee included) [F28]. This article therefore treats it only as background evidence for "a post-operative diet is not better the more liquid it is", and does not extrapolate it into individual dietary instructions after implant surgery [F28].

"How soon can I eat after an implant, and can I drink coffee" is a question-level topic; see canonical card KM-DENTAL-20 (in production).

7. Long-term maintenance: peri-implant health, mucositis and peri-implantitis

This section covers the gaps between the question-level canonical cards, and is the part this article dwells on most.

7.1 Definitions of the three states

The consensus report of workgroup 4 of the 2017 World Workshop set out a classification of peri-implant diseases and conditions [F6][F7][F8]:

• Peri-implant health: characterised by the absence of erythema, bleeding on probing, swelling and suppuration; and it is not possible to define a range of probing depths compatible with health [F8]. The report also states that peri-implant health can exist around implants with reduced bone support [F8].
• Peri-implant mucositis: its main clinical characteristic is bleeding on gentle probing, possibly with erythema, swelling or suppuration [F7]. There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis [F7].
• Peri-implantitis: a plaque-associated pathological condition occurring in the tissues around implants, characterised by inflammation of the peri-implant mucosa together with progressive loss of supporting bone [F6]. Affected sites show clinical signs of inflammation, bleeding on probing and/or suppuration, increased probing depths and/or recession of the mucosal margin, along with radiographic bone loss [F6].

7.2 Why a baseline record should be made when the prosthesis is fitted

The same consensus report recommends that the clinician obtain baseline radiographic and probing measurements following completion of the implant-supported prosthesis [F9]. The reason is written directly into the definition: identifying peri-implantitis depends on "progressive" bone loss and change in probing depth [F6], and without a baseline there is no starting point for comparison [F9].

7.3 Width of keratinized mucosa: the evidence is inconsistent

On the effect of keratinized mucosa on the long-term health of the peri-implant tissue, that consensus report's assessment is that the evidence is equivocal; the report does note, however, that keratinized mucosa may have advantages in terms of patient comfort and ease of cleaning [F10].

7.4 What the long-term data look like

The meta-analysis of prospective studies with more than 20 years of follow-up reports a 20-year implant survival rate of 93.0% (95% CI 91.6–94.1%) and a pooled mean marginal bone loss of 1.11 mm (95% CI 0.55–1.68 mm) [F1]. That analysis also states that the certainty of the evidence (GRADE) was rated moderate for both survival and marginal bone loss, and that this rating was limited by substantial heterogeneity [F1].

These are population-level statistical results and cannot be used to estimate the outcome for any individual patient [F1][F2]. Actual treatment and its results vary from person to person and must be assessed by a dentist.

8. The logic of what costs are made of (this section gives no monetary amount)

This article belongs to the international-literature education track and does not touch any country's fee arrangements or insurance coverage; what follows sets out only the universal logic of why the cost of an implant course of care is made up of several items.

1. However many steps the course contains, that is how many categories of item there will be: whether bone augmentation is needed is itself a fork in the structure of the course — GBR, sinus augmentation, alveolar ridge preservation and other additional techniques are needed only when bone volume is insufficient [F14].
2. Material categories differ: bone graft materials fall into four types, and the literature has no consensus on which is superior, so the choice of material is a case-by-case judgement rather than a single standard [F13].
3. Managing complications is a foreseeable cost dimension: maxillary bone augmentation techniques each carry their own pooled complication rate (that review does not cover alveolar ridge preservation, and is not extrapolated to the mandible) [F15], while the long-term cost of implant maintenance and of managing complications was, in the cost-effectiveness review set in severe periodontal disease, noted as possibly surpassing the cost of preserving and maintaining the existing teeth — that review being an indirect juxtaposition of 12 publications rather than a head-to-head comparison, with a cost structure that varies with each locality's health-care system [F25].
4. Maintenance is a long-term item, not a one-off outlay: implants present complications and require strict maintenance [F26], and they need baseline records and subsequent follow-up [F9].
5. Health economics is itself a formally listed issue in the implant field: the 4th EAO Consensus Conference listed the health-economic dimension alongside antibiotic prophylaxis, peri-implantitis and patient-reported outcomes as key issues [F21].

Local systems and costs (including local fee rules, the scope of insurance coverage, and how to break down and reconcile a quotation) are covered in the corresponding canonical cards (TW): KM-DENTAL-09 and KM-DENTAL-10, and in the systems-level domain article KM-DENTAL-PILLAR-12. This article does not deal with any country's coverage or fee regulations.

9. Risk factors (indications; possible side effects and complications; situations of elevated risk)

9.1 Dimensions of the indication judgement

The position of the implant requires sufficient bone volume for it to be placed where the restoration requires; the discussion of bone augmentation is entered into only when bone volume is insufficient [F14]. Whether a case is suitable must be assessed by a dentist against the individual's bone and soft-tissue conditions, general health and prosthetic plan.

9.2 Possible side effects and complications

• Post-operative pain and discomfort: among the primary outcome measures assessed in implant surgery research (pain, oedema, trismus, discomfort and use of rescue medication) [F17].
• Complications related to maxillary bone augmentation: in the review quantifying maxillary bone augmentation techniques (sinus lift, guided bone regeneration, onlay grafting, mixed techniques), membrane or graft exposure, wound dehiscence and infection were the more frequent types; the pooled rate for each technique is in section 4.2. That review did not analyse alveolar ridge preservation (ARP), and its figures are not extrapolated to the mandible [F15].
• A higher incidence of post-operative complications was observed in the immediate implant placement group: in the review of 11 randomised controlled trials comparing immediate implant placement with alveolar ridge preservation, the two groups were similar on three outcomes — horizontal width change, facial gingival margin change and patient-reported satisfaction (P > .05) — but post-operative complications were higher in the immediate implant placement group (p < 0.05) [F16]; implant failure in the same review did not reach statistical significance (OR 2.09, 95% CI 0.98 to 4.44) [F16].
• Peri-implant mucositis and peri-implantitis: plaque-associated, the latter accompanied by progressive loss of supporting bone [F6][F7].
• Long-term failure: in the meta-analysis with ≥20 years of follow-up, only 44 of 115 implant failures had their cause explicitly reported; among those cases with a reported cause, biological and mechanical causes were almost equally distributed, while the original studies did not report the causes of the other cases [F2].

9.3 Situations the literature marks as carrying elevated risk

• The association between smoking and implant failure is graded highly suggestive [F3].
• Periodontally compromised patients versus periodontally healthy patients is one of the associations graded suggestive in that umbrella review [F4].
• Surgical and prosthetic factors such as implant length, surface treatment, and healing and loading protocol are also on the list of associations related to failure risk; the three that count as high-certainty evidence are turned versus anodized surface, submerged versus nonsubmerged healing, and bone augmentation with long implants versus short implants, in every case with the former associated with a higher risk of implant failure [F4].
• It must be remembered at the same time that no observational association in that review was graded convincing [F5].

All of the above are population-level associations and do not amount to a causal determination for any individual [F5]. Whether a situation makes treatment inadvisable must be assessed by a dentist.

9.4 Overview of the red flags for seeking care (when to go back to a dentist)

This section lists only items the literature marks as pathological signs, and does not replace a diagnosis:

• Signs of inflammation around the implant, bleeding on probing and/or suppuration, increased probing depth or recession of the mucosal margin, together with bone loss seen radiographically — the clinical characteristics of peri-implantitis [F6].
• Bleeding on gentle probing, with erythema, swelling or suppuration — the main clinical characteristics of peri-implant mucositis [F7].
• Membrane or graft exposure, wound dehiscence or infection after maxillary bone augmentation surgery — the complication types most often recorded in that review for maxillary bone augmentation techniques [F15].

If any of these occur, please return promptly for assessment by a dentist. Actual treatment and its results vary from person to person.

This section lists only "the types of sign the literature marks as pathological", and deliberately provides no severity criteria and no timing criteria (for instance, on which post-operative day a given sign counts as abnormal, or what degree warrants emergency care) — those are question-level topics, and severity judgement and red flags after bone augmentation are covered in canonical card KM-DENTAL-28 (in production).
