F-Units (fact-unit ledger)

• F1｜confidence: verified｜basis: peer_reviewed (PMID 40523497)｜period: published in 2025; based on the 2017 World Workshop criteria｜geo: universal｜span: 「The weighted mean prevalence of peri-implant mucositis was 63.0 % (CI: 57.6-68.2 %) at the patient level and 59.2 % (CI: 55.8-62.4 %) at the implant level」「Peri-implantitis was observed in 25.0 % (CI: 21.1-29.3 %) of patients and 18.0 % (CI: 15.8-20.5 %) of implants」「In non-smokers, the implant-level prevalence of peri-implant mucositis and peri-implantitis was 38.2 % (CI: 33.4-43.2 %) and 5.2 % (CI: 3.6-7.5 %), respectively」「The risk of bias was high in 50 %, moderate in 45 %」「The findings highlight the high worldwide prevalence of peri-implant diseases, emphasizing the need for uniform diagnostic protocols」｜caveat: 20 cross-sectional studies were included; half had high risk of bias. Population prevalence is not an individual risk.
• F2｜confidence: verified｜basis: peer_reviewed (PMID 36261829)｜period: searched from 2005-01 to 2021-12; published in 2022｜geo: universal｜span: 「Prevalence of peri-implantitis was 19.53% (95% CI 12.87-26.19) at the patient-level, and 12.53% (95% CI 11.67-13.39) at the implant-level and it remains highly variable even following restriction to the clinical case definition」「estimates of its prevalence fluctuate very much. This may be due to the wide variety of disease definitions」｜caveat: 57 studies were included; the authors specifically attribute variation to differences in definitions.
• F3｜confidence: verified｜basis: clinical_guideline (PMID 25626479, 11th European Workshop on Periodontology consensus report)｜period: published in 2015｜geo: universal｜span: 「The management of peri-implant mucositis is considered as a preventive measure for the onset of peri-implantitis」「meta-analysis estimated a weighted mean prevalence for peri-implant mucositis of 43% (CI: 32-54%) and for peri-implantitis of 22% (CI: 14-30%)」「lack of regular supportive therapy in patients with peri-implant mucositis was associated with increased risk for onset of peri-implantitis」「whereas plaque accumulation has been established as aetiological factor, smoking was identified as modifiable patient-related and excess cement as local risk indicator」「patient-administered mechanical plaque control (with manual or powered toothbrushes) has been shown to be an effective preventive measure」「implant placement and prosthetic reconstructions need to allow proper personal cleaning, diagnosis by probing and professional plaque removal」｜caveat: Consensus report; its recommendation level is not an instruction for an individual procedure.
• F4｜confidence: verified｜basis: peer_reviewed (PMID 30904559)｜period: searched from 1997 to 2018-01; published in 2019｜geo: universal｜span: 「The summary estimate for 10-year survival at the implant level was 96.4% (95% CI 95.2%-97.5%)」「The sensitivity meta-analysis summary estimate of survival was 93.2% (95% CI 90.1% to 95.8%)」「demonstrated a possible doubling of the risk of implant loss in the older age groups」｜caveat: 18 prospective observational studies; survival means the implant remains in the mouth, not “free of complications.”
• F5｜confidence: verified｜basis: peer_reviewed (PMID 39305362)｜period: published in 2024｜geo: universal｜span: 「Three prospective studies (n = 237 implants) revealed a mean implant survival rate of 92% (95% CI: 82% to 97%), decreasing to 78% (95% CI: 74%-82%) after imputation」「A total of five retrospective studies (n = 1440 implants) showed a survival rate of 88% (95% CI: 78%-94%)」「follow-up is essential and shouldn't end after insertion or even after 10 years」｜caveat: Small sample (237 implants in prospective studies); limited to rough-surface screw-shaped titanium implants. The pre- and post-imputation difference reflects handling of loss to follow-up and must not be cited selectively.
• F6｜confidence: verified｜basis: peer_reviewed (PMID 39466662)｜period: searched to 2024-04; published in 2025｜geo: universal｜span: 「HP patients had a significantly greater risk for implant loss (HR: 1.75; 95% CI: 1.28-2.40; p = 0.0005」「and peri-implantitis (3.24; 95% CI: 1.58-6.64; p = 0.001」「a history of periodontitis has been proved to significantly increase the risk for implant loss, particularly at long follow-up」｜caveat: 14 prospective cohorts; the authors note heterogeneity in case definitions and assessment methods.
• F7｜confidence: verified｜basis: peer_reviewed (PMID 23062125)｜period: mean follow-up ≥5 years; published in 2012｜geo: universal｜span: 「Only 66.4% of the patients were free of any complications after 5 years」「fractures of the veneering material (13.5%), peri-implantitis and soft tissue complications (8.5%), loss of access hole restoration (5.4%), abutment or screw loosening (5.3%), and loss of retention of cemented FDPs (4.7%)」「biological and technical complications were frequent (33.6%)」｜caveat: Limited to implant-supported fixed dental prostheses; literature from 2012, and material generations have changed.
• F8｜confidence: verified｜basis: peer_reviewed (PMID 23062124)｜period: mean follow-up ≥5 years; published in 2012｜geo: universal｜span: 「survival of implants supporting SCs at 5 years amounted to 97.2% (95% CI: 96.3-97.9%), and at 10 years amounted to 95.2% (95% CI: 91.8-97.2%)」「The survival of implant-supported SCs was 96.3% (95% CI: 94.2-97.6%) after 5 years and 89.4% (95% CI: 82.8-93.6%) after 10 years」「a cumulative incidence of 8.8% (95% CI: 5.1-15.0%) for screw-loosening, 4.1% (95% CI: 2.2-7.5%) for loss of retention, and 3.5% (95% CI: 2.4-5.2%) for fracture of the veneering material after 5 years」「The cumulative 5-year aesthetic complication rate amounted to 7.1% (95% CI: 3.6-13.6%)」｜caveat: Limited to single implant crowns; implant survival and crown survival are two different measures.
• F9｜confidence: verified｜basis: peer_reviewed (PMID 30109300)｜period: published in 2018; 16 studies included｜geo: universal｜span: 「Patients had high expectations, with function followed by aesthetics being the most important expected improvements」「Costs were a major factor against implant-based therapy」「The expectations that implants will last a lifetime and require no special needs of oral hygiene were of concern」「Prior to treatment, patients have high expectations of implant therapy. In general, these expectations are met」｜caveat: Heterogeneous study designs; the authors state that comparability is limited.
• F10｜confidence: verified｜basis: peer_reviewed (PMID 40192114)｜period: published in 2025｜geo: universal｜span: 「The incidence of neurosensory alterations in patients with implants placed at a distance ≥ 2 mm from the mandibular canal was 0%」「for implants placed at a distance of 0-1 mm from the mandibular canal, the incidence of neurosensory alterations was 68%」「patients with implants that intruded into the canal had an incidence of 53% in the development of neurosensorial alterations」「Clinicians should be aware of the potential risk of nerve injury and adopt appropriate precautions, including meticulous preoperative planning and three-dimensional radiographic images」｜caveat: 0% is an observation in a particular study stratum, not proof that it cannot occur at that distance; interpretation requires the stratification conditions and sample size.
• F11｜confidence: verified (anchored to F15 of card #28)｜basis: peer_reviewed (PMID 34074573)｜period: nationwide registry from 1997 to 2013; published in 2022｜geo: universal｜span: 「other implant-related complications (infection, implant malposition, lack of bone at implant site, mechanical damage, or failed osseointegration)」｜caveat: Finnish compensation registry; used only for “nerve injury is a known complication category.”
• F12｜confidence: verified｜basis: peer_reviewed (PMID 39286589)｜period: literature from 2007 to 2020 included; published in 2024｜geo: universal｜span: 「The selected studies highlighted several aesthetic issues, such as recession, marginal bone loss, gingival loss, and pink aesthetic scores related to dental implants placed in the aesthetic zone」「Addressing these challenges necessitates meticulous treatment planning, effective soft tissue management, regular follow-ups, patient education, expectation management, and collaborative efforts among specialists」｜caveat: 14 studies included and a narrow time window; the authors acknowledge limited generalisability.
• F13｜confidence: verified｜basis: peer_reviewed (PMID 25358599)｜period: published in 2014｜geo: universal｜span: 「Most studies are cross sectional in nature and the quality of reporting varies considerably」「Expectations with respect to aesthetics and function are key attributes considered」｜caveat: Narrative review; no meta-analysis can be performed.
• F14｜confidence: verified｜basis: peer_reviewed (PMID 26701350)｜period: searched to 2015-06; published in 2016｜geo: universal｜span: 「implant therapy must not be limited to the placement and restoration of dental implants but to the implementation of PIMT」「our findings suggest reason to claim a minimum recall PIMT interval of 5 to 6 mo」「even in the establishment of PIMT, biologic complications might occur」｜caveat: The authors explicitly say intervals must be adjusted to the individual risk profile; this is not a fixed prescription.
• F15｜confidence: verified｜basis: peer_reviewed (PMID 39393606)｜period: searched to 2024-06; published in 2024｜geo: universal｜span: 「At implant level, a meta-analysis of 21 included cohort studies showed that smoking was associated with increased risk of early dental implant failure compared with non-smoking (odds ratio [OR], 2.59; 95 % confidence interval [CI], 2.08-3.23)」「with a total of 59,246 implants at implant level and 14,115 patients at individual level」｜caveat: Pooled observational studies, not causal inference; OR 2.59 comes from 21 cohort studies among 32, at implant level. Do not mix it with the individual-level OR 2.00.
• F16｜confidence: verified (2026-08-06 verified verbatim by ego-browser; anchored to VERIFIED-FACTS.md)｜basis: law｜period: current text｜geo: TW｜span: Taiwan National Health Insurance Act, Article 51: “Dentures, artificial eyes, spectacles, hearing aids, wheelchairs, canes, and other treatment equipment not required for positive therapy.”｜caveat: Coverage of an individual item is subject to current National Health Insurance Administration announcements; this card makes no coverage determination.
• F17｜confidence: verified (anchored to F8 of card #28)｜basis: peer_reviewed (PMID 35056347)｜period: published in 2021; 292 studies included｜geo: universal｜span: 「implants in smokers had a higher failure risk in comparison with non-smokers (OR 2.402, p < 0.001)」｜caveat: Pooled observational evidence, not causal inference.
• F18｜confidence: verified (2026-08-06 live-loaded with ego-browser; provider is displayed verbatim on the page)｜basis: official_statement｜period: dataset current state (metadata updated 2026-07-13)｜geo: TW｜span: Government open-data platform dataset “臺北市醫療收費標準,” provider “臺北市政府衛生局”｜caveat: A single-municipality example. Other county and municipality pages must be checked individually before publication. VERIFIED-FACTS.md also records OP’s 2026-08-05 ego-browser item-by-item verification that neither category stream in the National Health Insurance Administration’s “Medical Materials Price Comparison Website” includes dentistry; self-pay dental items must not be verified through that site. The verification-trap paragraph in this card relies on that record.　[On the official page the label appears in Chinese only: 「醫材比價網」]
• F19｜confidence: verified｜basis: peer_reviewed (PMID 23543525, Cochrane systematic review)｜period: searched to 2012-06; published in 2013｜geo: universal｜span: 「dental implants are kept load-free for 3 to 8 months to establish osseointegration (conventional loading)」「immediate (within 1 week), early (between 1 week and 2 months), and conventional (after 2 months) loading of osseointegrated implants」「the mean rate of implant failure in all 26 trials was a low 2.5%」「having a follow-up of 4 months to 1 year」｜caveat: 2.5% is a short-term figure from included trials with follow-up of 4 months to 1 year. It cannot be substituted for 10-year or 20-year figures; loading timing is a clinical judgment.
• F20｜confidence: verified (2026-08-06 verified verbatim by ego-browser)｜basis: law｜period: current text｜geo: TW｜span: Taiwan Medical Care Act, Article 63: “Medical care institutions shall explain the reasons for surgical operation, success rate, possible side-effects and risks to the patient or his/her legal agent, spouse, kin, or interested party, and must obtain his/her consent and signature on letter of consent for surgery and anesthesia before commencing with surgical procedure.”｜caveat: Statutory quotation, not legal advice.
• F21｜confidence: verified (2026-08-06 verified verbatim by ego-browser)｜basis: law｜period: current text｜geo: TW｜span: Taiwan Medical Care Act, Article 81: “When treating the patient, the medical care institution shall inform the patient or his/her legal agent, spouse, kin, or interested party of his/her condition, course of treatment, disposition, medication, expected condition, and possible ill effects.”｜caveat: Statutory quotation, not legal advice.
• F22｜confidence: verified (anchored to F10 of card #28)｜basis: peer_reviewed (PMID 36807599)｜period: searched to 2022-08; published in 2023｜geo: universal｜span: 「diabetic patients with dental implants and good glycaemic control have a significantly lower risk of peri-implantitis (odds ratio [OR] = 0.16」「risk of dental implant failure (OR = 3.76; 95% CI: 1.50-9.45; I2 : 0%) appears to be greater under irregular or no SPC」｜caveat: Indirect evidence; the authors note evidence limitations.
• F23｜confidence: verified｜basis: peer_reviewed (PMID 30328195)｜period: studies with follow-up ≥3 years; published in 2018｜geo: universal｜span: 「Therapy of peri-implantitis followed by regular supportive care resulted in high patient- and implant-level survival in the medium to long term」「Favourable results were reported, with clinical improvements and stable peri-implant bone levels in the majority of patients」｜caveat: Study designs and case definitions were heterogeneous; the authors say reporting quality affected data extraction.
• F24｜confidence: structural synthesis (editorial framework, not an external factual claim)｜basis: editorial_framework｜period: 2026-08-06｜geo: universal｜span: The principle of “neither cite nor dismiss online forum posts”; a five-way editorial framework matching common complaints to literature complication categories; the reading rule “read survival rates together with follow-up length and population”; and questions about fees and the verification trap (dentistry is outside the item categories of the National Health Insurance Administration’s Medical Materials Price Comparison Website, verified in VERIFIED-FACTS.md on 2026-08-05)｜caveat: Editorial communication framework, not a diagnostic tool and not a substitute for clinical judgment.
• F25｜confidence: verified｜basis: peer_reviewed (PMID 37339881)｜period: searched to 2022-07-21; published in 2023｜geo: universal｜span: 「Provision of SPIC following peri-implantitis therapy may prevent disease recurrence or progression」「with recall intervals varying between 2 months and annually」「Insufficient evidence is available to identify (i) a specific supportive care protocol for secondary prevention of peri-implantitis」｜caveat: 15 studies included; heterogeneity was too high for a meta-analysis.
• F26｜confidence: verified｜basis: peer_reviewed (PMID 27183062)｜period: searched to 2014-11; published in 2016｜geo: universal｜span: 「The survival rate for implant replacement at the second attempt was 88.84% (390/439; range, 71% to 94.6%)」「Thirty-one implants were replaced for a third attempt with a mean survival rate of 74.19% (23/31)」「Implant replacement is a reasonably feasible option for scenarios of early and late implant failure. However, modifiable risk factors must be controlled before proceeding for implant replacement」｜caveat: Only 7 studies (5 retrospective cohorts and 2 case series); the third-attempt sample had 31 implants and a wide range.
• F27｜confidence: verified｜basis: internal_dataset｜period: 2025-03 to 2026-08 GSC｜geo: TW｜span: backlog #7: 11 query items including “植牙後悔” and “植牙慘痛經驗ptt,” total impressions 270,300, across 6 sites:, and｜caveat: Impressions are an asset-level figure, not deduplicated traffic; this item is not output in publication conversion (08-05 ruling: internal data are not visible-layer content).
