• F1｜Topic-selection basis = reconciliation of all GSC data across 14 clinic sites: 12 terms including 「牙齦補肉手術費用」 「牙齦補肉手術保險理賠」 「牙齦補肉恢復期」 「牙齦增厚手術」 「牙齦補肉」 「植牙補肉」 「植牙補肉費用」 and 「牙齦補肉失敗ptt」 with combined impressions of 213,132 across 4 sites ｜source = internal ledger (appendix to km-dental-backlog.md #14)｜confidence=high｜basis=internal_dataset｜period=GSC retention window (from 2025-03-22)｜geo: TW｜caveat: impressions are property-level figures, not deduplicated traffic; this is internal data, not a medical claim, and is omitted in the publication conversion.
• F2 [structural synthesis]｜The four-way routing of “root coverage / keratinized-tissue widening / peri-implant soft-tissue augmentation / bone grafting is not gum grafting,” and the question “confirm which one before discussing cost,” are this site's editorial framework mapping patient queries to literature terms; not a factual claim or any institution's classification｜confidence=n/a｜basis=editorial｜geo: TW｜caveat: must not be marked unverified (to avoid creating fictitious verification work).
• F3｜Definition of gingival recession = displacement of the gingival margin apical to the cemento-enamel junction, exposing the root surface to the oral cavity｜source #3｜confidence=high｜basis=peer_reviewed (Cochrane systematic-review update, 2018)｜period=2018｜geo: universal｜caveat: definition statement, not an efficacy claim.
• F4｜Root-surface exposure is frequently associated with impaired esthetics, dentinal hypersensitivity, and carious and non-carious cervical lesions｜source #1｜confidence=high｜basis=clinical_guideline (narrative review of 2017 World Workshop classification consensus)｜period=2018｜geo: universal｜caveat: association statement, not a causal or incidence claim.
• F5｜With no pathology, monitoring particular sites is appropriate; where risk of pathology or progression is increased, or to meet patients' esthetic requirements, surgery to change the biotype and/or cover roots may be indicated｜source #1｜confidence=high｜basis=clinical_guideline｜period=2018｜geo: universal｜caveat: principle for indications, not an individual decision rule; this guide gives no self-diagnosis method.
• F6｜Thin periodontal biotypes carry greater gingival-recession risk; inadequate oral hygiene, orthodontic treatment, and cervical restorations may increase risk｜source #1｜confidence=moderate｜basis=clinical_guideline (retrospective literature synthesis)｜period=2018｜geo: universal｜caveat: risk-factor statement; relative risk is not quantified.
• F7｜RT1 = no interproximal attachment loss; RT2 = interproximal attachment loss less than or equal to the buccal site; RT3 = interproximal attachment loss greater than the buccal site. This classification predicted recession reduction at 6 months (109 treated sites, p<0.0001)｜source #2｜confidence=moderate｜basis=peer_reviewed (exploratory reliability study, 25 patients and 116 recessions)｜period=2011｜geo: universal｜caveat: single-center exploratory study; classification requires clinical measurement, and this guide gives no patient self-classification method.
• F8｜The Cochrane 2018 update (original 2009) included 48 RCTs: 1 at low risk of bias, 12 high, and 35 unclear. It concluded that SCTG shows slight improvement when both root coverage and wider keratinized tissue are expected; weaker evidence suggests ADM is a substitute with more similar outcomes; data on esthetic change related to patient opinion and preference are few｜source #3｜confidence=high｜basis=peer_reviewed (Cochrane systematic review)｜period=searched to 2018-01-15; on 2026-08-06, PubMed was rechecked: pub3 (2018) was the current valid Cochrane version and no update was found｜geo: universal｜caveat: the review authors rated the evidence for reported comparisons low or very low; this guide reports that faithfully.
• F9｜2022 systematic review and network meta-analysis: searched to 2021-09-30; 38 studies, 830 patients, and 1,265 recession defects included; SCTG＋CAF ranked near the top for mean root coverage, complete root coverage, and keratinized-tissue-width gain at 6 and 12 months, except enamel-matrix derivative＋CAF was better for mean root coverage at 12 months; authors described its status as gold standard｜source #4｜confidence=high｜basis=peer_reviewed (SR＋NMA)｜period=2022; a 2026-08-06 recheck found no updated NMA for the same clinical question (recent publications address adjunctive materials)｜geo: universal｜caveat: rankings arise from indirect comparisons, not individual efficacy prediction; this guide does not use rankings as recommendations.
• F10｜2025 systematic review and meta-analysis of multiple gingival recession (searched to 2024-05): 32 RCTs, 1012 patients, and 3589 recessions; mean root coverage 82.6% (95% CI 71.3–93.9), complete root coverage 62.7% (95% CI 57.0–68.4); low postoperative pain (VAS 0–10 mean 2.67; VAS 0–100 mean 24.34); no significant association between mean root coverage and patient esthetic perception｜source #5｜confidence=high｜basis=peer_reviewed (SR＋MA)｜period=2025 (current pooled-effect estimate for this topic; no update found on search 2026-08-06)｜geo: universal｜caveat: population = multiple recessions, procedures = CAF/tunnel with graft or substitute material; cannot be extrapolated to every “gum graft” operation or an individual prediction for a single defect.
• F11｜2020 network meta-analysis of esthetic and patient-related outcomes: 26 RCTs, 867 patients, and 1708 recessions; connective-tissue-graft-based procedures correlated with both greater patient satisfaction and greater postoperative morbidity｜source #6｜confidence=moderate｜basis=peer_reviewed (SR＋NMA)｜period=2020｜geo: universal｜caveat: morbidity means patient-reported pain and discomfort, not complication incidence.
• F12｜2022 meta-analysis: 13 RCTs, 701 patients, and 1,086 recessions; dentin-hypersensitivity suppression after surgical root coverage 70.8% (95% CI 64.4–76.6), I²=39.2%; authors concluded successful coverage is associated with hypersensitivity suppression｜source #7｜confidence=moderate｜basis=peer_reviewed (SR＋MA)｜period=2022｜geo: universal｜caveat: population-level estimate, not individual prediction; sensitivity has more than one cause.
• F13｜Network meta-analysis of 105 RCTs (95 root-coverage procedures and 10 non-root-coverage procedures): in the root-coverage-procedure analysis, ADM, collagen matrix, and connective-tissue grafting all significantly increased gingival thickness; keratinized tissue increased significantly only with connective-tissue grafting or ADM｜source #8｜confidence=high｜basis=peer_reviewed (SR＋NMA)｜period=2020｜geo: universal｜caveat: this conclusion is limited to the root-coverage-procedure subset and cannot be extrapolated to non-root-coverage procedures (widening keratinized tissue alone); outcomes are thickness and keratinized tissue, not esthetics or survival.
• F14｜Long-term (≥5 years) systematic review (searched to 2023-05-15): recession depth rose over time for all root-coverage procedures; autogenous grafts (SCTG or FGG) were associated with greater short-term keratinized-tissue-width gain and less increase in recession depth; gingival-margin stability correlated with keratinized-tissue width at short-term assessment｜source #9｜confidence=moderate｜basis=peer_reviewed (systematic review, 41 reports and 40 studies)｜period=2024｜geo: universal｜caveat: RCTs and non-RCTs included, with high heterogeneity; trend statement is not an individual prediction.
• F15｜2026 systematic review and network meta-analysis of peri-implant soft-tissue augmentation: 48 RCTs included (46 entered NMA); APF＋FGG ranked highest for keratinized-tissue-width gain and connective-tissue grafting performed better for mucosal-thickness gain; procedure and material selection were more critical than surgical timing｜source #10｜confidence=high｜basis=peer_reviewed (SR＋NMA)｜period=2026 (search date 2026-08-06: no update found; earlier version for the same topic was 2024 PMID 38704784, and this guide uses the newer one)｜geo: universal｜caveat: outcomes are tissue dimensions, not implant survival or disease prevention.
• F16｜2025 umbrella systematic review (10 systematic reviews published from 2012–2023): insufficient keratinized-mucosa width had significant effect sizes for mucosal recession, Gingival Index/modified Gingival Index, modified Plaque Index, and marginal bone loss; evidence was insufficient for effects on bleeding on probing, pocket depth, implant survival, and disease prevalence｜source #11｜confidence=moderate｜basis=peer_reviewed (umbrella review＋meta-meta-analysis)｜period=2025｜geo: universal｜caveat: association study, not causation; this guide does not claim surgery prevents peri-implant disease.
• F17｜2026 donor-site-complication systematic review (16 clinical studies published from 2019 to 2025-04): postoperative pain was more frequently reported, generally assessed with VAS; bleeding was less often reported and generally self-limiting; sensory disturbance was usually mild and transient and resolved during routine follow-up; no study reported serious infection or health-compromising complications; overall evidence strength was moderate｜source #12｜confidence=moderate｜basis=peer_reviewed (systematic review, no meta-analysis)｜period=2026｜geo: universal｜caveat: because of heterogeneity, the authors did not quantitatively pool data; this guide cites no complication-incidence figure.
• F18｜Randomized controlled trial (74 patients receiving FGG): pain and analgesic use recorded at 24, 48, and 72 hours after surgery with a 21-point numerical scale; at weeks 1, 2, 3, and 4, palatal early-healing index assessed wound color, epithelialization, swelling, granulation tissue, and bleeding on gentle palpation｜source #13｜confidence=moderate｜basis=peer_reviewed (RCT)｜period=2024｜geo: universal｜caveat: this guide only cites measurement time points, not intervention-group effects as general advice or a recovery-days promise.
• F19｜Review of 24 clinical studies: cigarette smoking negatively affects periodontal wound healing after surgical intervention｜source #14｜confidence=moderate｜basis=peer_reviewed (literature review)｜period=2012｜geo: universal｜caveat: same anchor as card #17; all evidence levels included, not a graded meta-analysis.
• F20｜After periodontal surgery, chlorhexidine rinsing can improve early wound healing and reduce plaque accumulation and gingival inflammation｜source #15｜confidence=moderate｜basis=peer_reviewed (RCT, 33 people)｜period=2024｜geo: universal｜caveat: same anchor as card #17; study disclosed industry funding; this guide neither recommends a product nor gives medication instructions.
• F21｜Article 21 of Taiwan's Medical Care Act: “The standards by which medical institutions collect medical fees shall be approved by the competent authority of the special municipality or county (city).”｜source #17｜confidence=high｜basis=law｜period=current text (HTTP 200 tested and wording checked on 2026-08-06)｜geo: TW｜caveat: same anchor as card #3; statutory paraphrase, not legal opinion.
• F22｜Article 22 of Taiwan's Medical Care Act: a medical institution collecting medical fees must issue a receipt stating the fee items and amounts; it may not violate fee standards by charging in excess or creating unauthorized fee items｜source #18｜confidence=high｜basis=law｜period=current text (HTTP 200 tested and both passages checked on 2026-08-06)｜geo: TW｜caveat: same anchor as card #3; statutory paraphrase, not legal opinion.
• F22b｜For teeth with both non-carious cervical lesions and gingival recession, restoring the lesion does not affect percentage root coverage｜source #16｜confidence=low｜basis=peer_reviewed (systematic review and meta-analysis, data extraction from 13 included studies)｜period=2024｜geo: universal｜caveat: the abstract's wording on sensitivity and esthetic perception is ambiguous; this guide does not cite that part, only the sentence on percentage coverage.
• F23｜Article 63 of Taiwan's Medical Care Act: before surgery, a medical institution must explain the reason for surgery and its success rate or possible complications and risks to the patient or relevant person, obtain consent, and have surgical and anesthesia consent forms signed｜source #19｜confidence=high｜basis=law｜period=current text (HTTP 200 tested and wording checked on 2026-08-06)｜geo: TW｜caveat: same anchor as card #17; the proviso “except in an emergency” is not cited in the body.
• F24｜Article 51 of Taiwan's National Health Insurance Act lists items outside coverage; item 3 includes cosmetic surgery and item 11 includes dentures, artificial eyes, spectacles, hearing aids, wheelchairs, crutches, and other non-actively therapeutic appliances｜source #20｜confidence=high｜basis=law｜period=current text (HTTP 200 tested and wording checked on 2026-08-06)｜geo: TW｜caveat: same anchor as cards #9/#17; statutory enumeration is not an individual-case conclusion; this guide makes no subsumption judgment.
• F25｜Article 87 of Taiwan's Medical Care Act: content that implies or alludes to medical business is medical advertising; publication of medical knowledge or research reports, patient health education, and academic publications that do not solicit medical business are not medical advertising｜source #21｜confidence=high｜basis=law｜period=current text (HTTP 200 tested and both passages obtained verbatim on 2026-08-06)｜geo: TW｜caveat: basis for this guide's positioning.
• F26｜Self-pay fee items follow fee standards approved by local competent authorities; verified example = Government Open Data Platform dataset 121913, “Taipei City Medical Fee Standards”｜source #22｜confidence=high｜basis=official_statement｜period=HTTP 200 tested on 2026-08-06; API returned the title verbatim｜geo: TW｜caveat: same anchor as cards #3/#17; pages for other cities and counties must be individually verified before scaling.　[On the official page the label appears in Chinese only: 「臺北市醫療收費標準」]
• F27｜Neither search path on the NHI medical-material price comparison website includes dental items; dental self-pay items cannot be verified through that website｜source = cross-card verified-facts file `km-compliance/VERIFIED-FACTS.md` (browser-tested by OP on 2026-08-05; first reported in card #3 with categories read individually)｜confidence=high｜basis=official_statement (test record)｜period=2026-08-05｜geo: TW｜caveat: this guide reuses a verified cross-card anchor and did not repeat the test; if the site later adds a dental category, this item must be rechecked.　[On the official page the label appears in Chinese only: 「醫材比價網」]
• F28 [unverified]｜Coverage status of gingival soft-tissue grafting in NHI payment standards｜source type: NHI announcement of medical-service benefit items and payment standards｜confidence=low｜basis=pending supplementation (www.nhi.gov.tw response to curl was restricted; this guide did not obtain a verbatim anchor; verify by browser before publication)｜geo: TW｜caveat: before verification, this guide makes no “covered/not covered” assertion.
• F29 [unverified]｜Whether commercial insurance pays for this procedure depends on policy terms｜source type: policy terms (no publicly citable policy sample obtained)｜confidence=low｜basis=pending supplementation｜geo: TW｜caveat: this site provides no claim opinion (editorial policy) and states only “depends on policy terms.”
• F30 [structural synthesis]｜The six-part breakdown—examination and diagnosis / surgery itself / graft source / concurrent procedures / follow-up and monitoring / later maintenance—and estimate-comparison advice are this site's editorial reading framework, not a factual claim or any institution's fee classification｜confidence=n/a｜basis=editorial｜geo: TW｜caveat: must not be marked unverified.
