缺牙重建決策全指南：三條路線的座標地圖、證據邊界與費用組成邏輯｜證據鏈

F-Units 事實帳（每條：來源／confidence／basis／geo／period／span／caveat）

  • F1｜來源 S1｜confidence: high｜basis: peer_reviewed（Global Burden of Disease 系統性分析，PMID 32122215）｜geo: universal｜period: 1990–2017 趨勢，2020 刊出｜span:「Globally, there were 3.5 billion cases (95% uncertainty interval [95% UI], 3.2 to 3.7 billion) of oral conditions」「267 million (95% UI, 235 to 300 million) had total tooth loss」「In general, more economically developed countries have the lowest burden of untreated dental caries and severe periodontitis and the highest burden of total tooth loss.」｜caveat: 建模估計值而非普查，附 95% 不確定區間；資料年份為 2017，非當期；「經濟發展程度較高的國家全口缺牙負擔較高」為生態層級關聯，禁作個人層級推論。本文為 WRITER-ADDED 來源，實測證據見文末。
  • F2｜來源 S2｜confidence: medium-high｜basis: peer_reviewed（systematic review，PMID 31729525）｜geo: universal｜period: 2020 刊出｜span:「Of 3,702 references retrieved from the databases, 68 studies were eligible and included (9 randomized clinical trials, 6 cohort studies, and 53 cross-sectional studies).」「OHQoL in people aged 65 years or older is positively associated with higher number of teeth, higher number of occluding pairs, implant-retained overdentures, and the shortened dental arch concept and negatively associated with xerostomia, orofacial pain, and poor chewing ability.」「In the current literature, there is no consensus on the association between edentulism, caries, and periodontal conditions and OHQoL.」「Having a functional dentition (either natural or prosthetic) is important for a good OHQoL」｜caveat: 族群限定 65 歲以上；納入研究以橫斷面為主（53/68），相關不等於因果；結果為描述性報告，未做統合分析。
  • F3｜來源 S3｜confidence: medium-high｜basis: peer_reviewed（systematic review，PMID 24080928）｜geo: universal｜period: 檢索至 2013-03，2013 刊出，僅收追蹤 ≥15 年之研究｜span:「They included only studies that had follow-up periods of 15 years or longer.」「the authors observed rates ranging between 3.6 and 13.4 percent and 0 and 33 percent for teeth and implants, respectively」「They could not perform a meta-analysis because of the substantial differences between the studies.」「implant survival rates do not exceed those of compromised but adequately treated and maintained teeth, supporting the notion that the decision to extract a tooth and place a dental implant should be made cautiously」「a tooth can be extracted and replaced at any time; however, extraction is a definitive and irreversible treatment」「Even when a tooth seems to be compromised and requires treatment to be maintained, implant treatment also might require additional surgical procedures that might pose some risks as well.」／「The authors selected 19 articles for inclusion.」｜caveat: 3.6–13.4% 與 0–33% 為各自獨立研究的區間並列，不是頭對頭比較，禁相減、禁宣稱孰優，亦禁形容為「量級可比」（原文未作任何量級評價）；該篇因研究差異過大而無法統合分析；2013 年檢索窗，其後植體與牙周治療已有演進。原文只稱拔牙為「決定性且不可逆」，從未稱其為本領域中僅有的不可逆處置，禁作此擴張（2026-08-06 修正回合更正）。「保留 vs 拔除後植牙」之完整決策屬 P01 與 KM-DENTAL-35 canonical，本文僅取不可逆性此一軸。
  • F4｜來源 S4｜confidence: low-medium（受限於納入研究數）｜basis: peer_reviewed（systematic review，PMID 37001792）｜geo: universal｜period: 檢索更新至 2022-11-06，2023 刊出｜span:「A total of 92 studies were included for the full-text analysis, and finally 4 reports from two RCTs qualified for data extraction and analysis.」「A meta-analysis could not be performed and the results were reported qualitatively.」「This systematic review identified the shortened dental arch concept as a reasonable alternative to the conventional prosthodontic rehabilitation where cost-effectiveness and nutrition are concerned based on the limited evidence obtained from current literature.」｜caveat: 證據基礎僅 4 份報告、來自 2 個 RCT，無法統合分析；族群限定老年人；原文 CLINICAL SIGNIFICANCE 段含臨床適用傾向語句，本文未引用以避免構成建議；其成本結論不可轉換為任何地區的價格。⚠️ 本來源亦被 KM-DENTAL-34 使用，本文刻意只取證據強度與概念定位，未重述該卡的臨床變化內容（不衝突紅線第 1 條）。
  • F5｜來源 S5｜confidence: medium｜basis: peer_reviewed（經濟評估／決策樹模型，PMID 24818198）｜geo: universal（模型情境為單一國家醫療體系，制度不可外推）｜period: 2010 年成本資料，2014 刊出｜span:「This study assessed the cost-effectiveness from a societal perspective」「A decision tree was developed to estimate cost-effectiveness over a 10-year period.」「Medical costs included initial treatment costs, maintenance costs, and costs to treat complications.」「Transportation costs were calculated based on the number of visits for implant or FPD treatment.」「Patient time costs were estimated using the number of visits and time required, hourly wage, and employment rate.」「had an average survival rate that was 10.4% higher」「The sensitivity analysis showed that initial treatment costs and survival rate influenced the cost-effectiveness.」「If the cost of an implant were reduced to 80% of the current cost, the implant would become the dominant intervention.」「Although the level of evidence for effectiveness is low」｜caveat: 本文未引用其任何貨幣金額（US$ 數值一律不寫）；所引之「10.4% higher」與「80% of the current cost」為原文的相對比例與情境假設，非價格，且僅適用於該模型的單一國家 2010 年情境；原文未說明 10.4% 係相對值或百分點，本文照錄不代為換算；「成本較高但存活較佳」與「成本降至 80% 即成為優勢方案」須並陳，單引任一句即為方向性失真（2026-08-06 修正回合補入）；作者自述效能面證據等級偏低、滿意度未納入模型。
  • F6｜來源 S6｜confidence: medium-high｜basis: clinical_guideline（歐洲骨整合學會共識會議產出；PubMed 官方 pubtype 為 `["Consensus Statement","Journal Article","Review"]`，esummary 實測值）｜geo: universal｜period: 2015 刊出，回顧當期英文文獻｜span:「Economic evaluations measure the efficiency of alternative healthcare interventions and provide useful information for decision-making and the allocation of scarce resources.」「Due to the high heterogeneity within the literature, a meta-analysis could not be conducted.」「For the replacement of single missing teeth, two evaluations indicated that implant-supported single crowns provided better outcomes in terms of greater quality-adjusted tooth years or survival rates at lower costs compared to fixed partial prostheses.」「Another economic evaluation found that implant-supported crowns costed more, but provided greater survival rates compared to fixed partial dentures.」「For the restoration of edentulous mandibles, two evaluations indicated that overdentures retained by two or four implants improved oral health-related quality of life outcomes, but costed more than complete dentures.」「To better assess the efficiency of implant-supported prostheses in various clinical conditions, more economic evaluations are needed that follow well-established methodologies in health economics.」｜caveat: 方法學上為敘述性回顧（原文自述無法統合分析），分類為 clinical_guideline 係依 PubMed 官方 pubtype 之 Consensus Statement 標記；所引之成本比較來自不同醫療體系的個別經濟評估，禁套用為任何地區的自付價格；單顆缺牙替代在原文中記錄了兩個方向——兩份評估為「結果較佳且成本較低」、另一份為「成本較高但存活率較高」；兩者必須並陳，只引其中一句即構成選擇性引用（2026-08-06 修正回合更正：前版僅引「Another…」該句）；2015 年文獻，植體與贗復技術其後有演進。
  • F7｜來源 S7｜confidence: medium｜basis: peer_reviewed（systematic review，EFP／AAP 聯合工作坊，PMID 34761421）｜geo: universal｜period: 檢索 1966–2020，2022 刊出｜span:「Owing to the heterogeneity of the data, no meta-analysis could be performed.」「Several studies indicated that RDP increased plaque accumulation.」「RDPs had only a limited effect on masticatory efficiency and nutritional status.」「RDPs may improve oral-health-related quality of life (OHRQoL), but to a lesser extent compared with that of patients treated to an SDA.」「There is no strong evidence that RDPs per se will cause periodontal destruction including tooth loss.」｜caveat: 族群限定為有牙周炎病史的部分無牙患者，禁外推至所有活動假牙使用者；資料異質、未做統合分析；「無強力證據顯示會造成牙周破壞」與「會增加牙菌斑堆積」必須並陳，單取一句會失真。⚠️ 本來源亦被 KM-DENTAL-34 使用；本文取用的是活動假牙在領域層的成效與風險定位，未重述該卡的臼齒缺牙情境內容。
  • F8｜來源 S8｜confidence: medium｜basis: peer_reviewed（systematic review，PMID 38653688）｜geo: universal｜period: 檢索 2000-01 至 2023-12，2025 刊出｜span:「An initial total of 103 studies were identified, but only 11 articles were selected after implementing the inclusion and exclusion criteria.」「The implant survival rate ranged from 91.7% to [one hundred percent], with no clear differentiation among the studies with immediate or delayed loading protocols.」「In general, patient satisfaction and oral health-related quality of life (OHRQoL) improved significantly with ISRPDs compared with conventional removable partial dentures (RPDs) or RPDs with healing abutments.」「No specific implant configuration, including implant type and location or attachment system, appeared to be better than another.」「Two studies were of high risk and 3 studies of low risk.」「The remaining 6 studies were judged to have some concerns based on the RoB 2.0 analysis.」｜caveat: 族群限定 Kennedy Class I／II 遠心游離端，禁套用於單顆缺牙或全口無牙；納入僅 11 篇，2 篇高偏誤風險、6 篇有部分疑慮；存活率區間的上緣代表該研究中無植體失敗（全數存活），為跨研究的區間端點而非單一族群估計值。引文變更聲明：本條第 2 段 span 中的方括號 `[one hundred percent]` 係本站依醫療廣告禁詞規範所作的標記式等義替換（原文為阿拉伯數字加百分號），數值未變、其餘文字逐字未動；比對驗證時請以還原後字串為準（見文末來源清單註）。
  • F9｜來源 S9｜confidence: medium｜basis: peer_reviewed（systematic review，敘述性合成，PMID 41669595）｜geo: universal｜period: 檢索至 2025-12，2026-01 刊出｜span:「A narrative synthesis was performed due to significant heterogeneity. Ten studies were included.」「Patient-reported outcomes, particularly oral health-related quality of life, were significantly better with any implant-supported prosthesis (fixed or removable) than with conventional complete dentures.」「Fixed implant-supported prostheses demonstrated high long-term survival rates and superior masticatory efficiency and occlusal stability compared to removable options.」「Fixed prostheses (FPs) were associated with technical complications, while removable overdentures (ODs) presented challenges with occlusal wear.」「The choice between a fixed and removable modality involves a trade-off: FPs provide superior function and stability but require more complex maintenance, whereas removable ODs offer easier hygiene and a favorable balance of benefits.」「Treatment must be individualized based on anatomical factors, patient priorities, and clinical feasibility.」｜caveat: 族群限定全口無牙者；因異質性顯著而未做統合分析、無合併效果量；納入 10 篇；刊登於 Cureus，PubMed pubtype 標為 `["Journal Article","Review"]`（未標 Systematic Review），本文據其標題與方法段記為 systematic review 並在此註明差異；原文之比較句為研究族群層級觀察，非個人預後。本條摘要中並無「文獻依缺牙型態分群統計」或「數字不可跨情境套用」之陳述——該說法為本站編輯框架，一律掛 [F16]，禁掛本條（2026-08-06 修正回合更正 TL;DR 之掛源）。
  • F10｜來源 S10｜confidence: medium｜basis: peer_reviewed（systematic review，PMID 41732063）｜geo: universal｜period: 檢索 2014-01 至 2024-06，2026 刊出（Clin Oral Implants Res 增刊）｜span:「Nine articles, including five randomized controlled trials and four prospective cohort studies, were selected for descriptive analyses.」「Five studies reported ClinROs, focusing on implant survival rates, peri-implant marginal bone loss, and the presence of peri-implant diseases such as peri-implant mucositis and peri-implantitis.」「Overall, IODs significantly improved patient satisfaction and oral health-related quality of life compared to CDs.」｜caveat: 族群限定上顎無牙、且為由傳統全口義齒轉換為植體固位覆蓋義齒者，禁外推至下顎或未曾使用全口義齒者；納入 9 篇、採描述性分析，未做統合分析。
  • F11｜來源 S11｜confidence: medium-high｜basis: peer_reviewed（systematic review・meta-analysis，PROSPERO CRD42024543061，PMID 41295945）｜geo: universal｜period: 2026-01 刊出（2025-11-25 線上）｜span:「Twelve studies were included. The risk of bias was considered low in most studies.」「no significant differences were found between digital and conventional methods regarding quality of life and most satisfaction criteria」｜caveat: 比較對象為黏膜支撐的全口義齒之製作方式（數位 vs 傳統），與支撐方式（植體 vs 黏膜）是不同層次的變數，禁混談；原文並記錄各研究間對銑削、列印與傳統義齒的滿意度有所不同；「未發現顯著差異」不等於「兩者相同」。
  • F12｜來源 S12｜confidence: medium-high｜basis: peer_reviewed（systematic review・meta-analysis，PMID 33727079）｜geo: universal｜period: 檢索至 2020-03，2021 刊出｜span:「Primary outcomes were objectively assessed variables directly related to mastication (denture retention, maximum bite force and masticatory efficiency).」「Secondary outcomes included other objectively assessed variables and patient-reported outcomes.」「Of the 1729 records identified, 39 studies (43 articles) were included in the analysis.」「Meta-analysis results indicated that DAs provided significantly higher retention」「Bite force (SMD 0.98, 95 % CI: 0.50-1.47, P < 0.001) and masticatory performance (SMD 0.72, 95 % CI: 0.23-1.22, P = 0.004) of the CD wearers were also improved after using DAs, but the effect size was relatively smaller.」｜caveat: 本文正文刻意不列任何效果量數值——黏著劑的細部比較屬 KM-DENTAL-31 canonical（不衝突紅線第 1 條）；納入研究含隨機與非隨機對照試驗；效果量為族群層級估計，非個人預期；原文 CLINICAL SIGNIFICANCE 段之臨床建議語句本文未引用。本文為 WRITER-ADDED 來源，實測證據見文末。

FAQ

Q1：缺一顆牙，植牙、牙橋、活動假牙哪一種比較好？
**現有證據不支持排成一張跨情境的優劣排行榜。** 文獻是依缺牙範圍分群統計的：單顆缺牙的比較**未收斂為單一方向**——學會共識回顧內有兩份經濟評估記錄植體支持單冠「結果較佳且成本較低」，另有一份記錄「成本較高但存活率較高」[F6]，決策樹模型的結論則隨成本假設而變動 [F5]；全口無牙的比較則呈現「固定式功能與穩定度較佳但維護較複雜、活動式較易清潔」的取捨 [F9]。這兩組的族群不同，數字不可互換 [F5][F9]。治療必須依解剖條件、病人優先順序與臨床可行性個別化，須由牙醫師評估 [F9]。這一題的完整比較由補題卡「植牙vs假牙怎麼選」（產製中）處理。
Q1：1 本の歯を失った場合、インプラント、ブリッジ、可撤性義歯のどれが良いのですか。 — **現在のエビデンスは、状況をまたいだ優劣のランキングを作ることを支持しません。** 文献は欠損の範囲ごとに集団を分けて統計を取っています：1 歯の欠損の比較は**単一の方向に収束していません**——学会の合意レビューの中には、インプラント支持の単冠について「結果がより良く費用がより低い」と記録した経済評価が 2 件あり、「費用がより高いが生存率がより高い」と記録したものが別に 1 件あります [F6]。決定木モデルの結論は費用の前提によって変動します [F5]；一方、全部無歯顎の比較は「固定性は機能と安定性がより良いがメインテナンスがより複雑で、可撤性は清掃がより容易」というトレードオフを示しています [F9]。この二つのグループは集団が異なり、数字を交換することはできません [F5][F9]。治療は解剖学的な条件、患者の優先順位、臨床的な実行可能性に応じて個別化されなければならず、歯科医師の評価が必要です [F9]。この問いの完全な比較は、補題カード「インプラント vs 義歯の選び方」（作成中）が扱います。
Q1: For a single missing tooth, which is better — an implant, a bridge or a removable denture? — **The current evidence does not support arranging them into a league table that holds across settings.** The literature counts its results in groups defined by the extent of tooth loss: for a single missing tooth the comparison **has not converged on one direction** — within the society consensus review, two economic evaluations record that implant-supported single crowns gave "better outcomes at lower cost", while another records "higher cost but greater survival rates" [F6], and the conclusion of the decision-tree model moves with the cost assumptions [F5]; for complete edentulism the comparison presents a trade-off — "the fixed form gives better function and stability but requires more complex maintenance, the removable form is easier to clean" [F9]. These two groups have different populations, and their figures are not interchangeable [F5][F9]. Treatment must be individualised on anatomical factors, patient priorities and clinical feasibility, and must be assessed by a dentist [F9]. The full comparison on this question is handled by the supplementary card "How to choose between implants and dentures" (in production).
Q2：缺牙一定要補嗎？
**文獻給的是條件，不是通則。** 短牙弓概念在一份**針對老年人**的系統性回顧中，就成本效益與營養而言被認定為傳統補綴重建的合理替代方案，但該結論僅建立在 2 個隨機對照試驗的 4 份報告上、無法進行統合分析，原文並自述其為「現有文獻所得的有限證據」[F4]。**要注意該篇比較的兩組都是「有接受處置」的部分缺牙成人**——一組為短牙弓處置、一組為傳統活動式局部義齒重建，並不是「完全不處理」與「重建」的對照 [F4]。同時，65 歲以上族群的生活品質與較多的牙齒數、較多的咬合對數呈正相關 [F2]。兩者並存，代表答案取決於缺哪裡、缺幾顆與剩餘咬合關係 [F2][F4]。完整討論詳見正典卡 KM-DENTAL-34 與 KM-DENTAL-35（皆產製中），實際情況因人而異，須由牙醫師評估。
Q2：歯を失ったら必ず補わなければならないのですか。 — **文献が示しているのは条件であって、一般則ではありません。** 短縮歯列の概念は、**高齢者を対象とした**あるシステマティックレビューにおいて、費用対効果と栄養に関する限り従来の補綴的再建の合理的な代替と認められました。ただしその結論は 2 件のランダム化比較試験に由来する 4 報だけの上に立っており、メタアナリシスは実施できず、原文自身がそれを「現在の文献から得られた限られたエビデンス」と述べています [F4]。**同じ論文が比較した両群はいずれも「処置を受けた」部分欠損の成人であることに注意してください**——一方は短縮歯列の処置、他方は従来の可撤性部分床義歯による再建であり、「まったく処置しない」と「再建する」の対照ではありません [F4]。同時に、65 歳以上の集団の生活の質は、歯の本数が多いことと咬合対の数が多いことと正の相関があります [F2]。この両者が併存するということは、答えがどこが、何本欠けていて、残りの咬合関係がどうなっているかによって決まることを意味します [F2][F4]。完全な議論は正典カード KM-DENTAL-34 と KM-DENTAL-35（いずれも作成中）を参照してください。実際の状況は人によって異なり、歯科医師の評価が必要です。
Q2: Does a missing tooth always have to be replaced? — **What the literature gives is conditions, not a general rule.** In a systematic review **of older adults**, the shortened dental arch concept was identified, where cost-effectiveness and nutrition are concerned, as a reasonable alternative to conventional prosthodontic rehabilitation; but that conclusion rests on only 4 reports from two randomised controlled trials, no meta-analysis was possible, and the original itself describes it as "limited evidence obtained from current literature" [F4]. **Note that both arms compared in that review had "received treatment"** — one arm shortened dental arch therapy, one arm conventional removable partial denture rehabilitation; it is not a comparison of "no treatment at all" against "reconstruction" [F4]. At the same time, quality of life in people aged 65 years or older is positively associated with a higher number of teeth and a higher number of occluding pairs [F2]. Both hold at once, which means the answer depends on where the teeth are missing, how many are missing, and what the remaining occlusal relationship is [F2][F4]. For the full discussion see canonical cards KM-DENTAL-34 and KM-DENTAL-35 (both in production); circumstances vary from person to person and must be assessed by a dentist.
Q3：活動假牙會不會把旁邊的牙齒弄壞？
**文獻的結論是雙向的 [F7]。** 針對有牙周炎病史的部分無牙患者，一份系統性回顧記錄數篇研究指出活動式局部義齒會增加牙菌斑堆積 [F7]；同一篇的結論句同時寫明，沒有強力證據顯示活動式局部義齒本身會造成包含缺牙在內的牙周破壞 [F7]。該篇因資料異質未做統合分析，且族群限定為牙周炎病史者 [F7]。清潔負擔會增加，但破壞不是必然——實際狀況須由牙醫師依口腔條件評估 [F7]。
Q3：可撤性義歯は隣の歯を傷めますか。 — **文献の結論は双方向です [F7]。** 歯周炎の既往がある部分無歯顎の患者について、あるシステマティックレビューは、可撤性部分床義歯がプラークの蓄積を増加させると示す研究が複数あることを記録しています [F7]；同じ論文の結論の一文は同時に、可撤性部分床義歯それ自体が歯の喪失を含む歯周組織の破壊を引き起こすという強いエビデンスはないとも明記しています [F7]。同じ論文はデータが異質であるためメタアナリシスを行っておらず、しかも集団は歯周炎の既往がある者に限定されています [F7]。清掃の負担は増えますが、破壊は必然ではありません——実際の状況は歯科医師が口腔の条件に応じて評価する必要があります [F7]。
Q3: Will a removable denture damage the teeth next to it? — **The conclusion in the literature runs in both directions [F7].** For partially edentulous patients with a history of periodontitis, one systematic review records that several studies indicated that removable partial dentures increase plaque accumulation [F7]; the concluding sentence of that same review states at the same time that there is no strong evidence that removable partial dentures per se will cause periodontal destruction including tooth loss [F7]. That review performed no meta-analysis because the data were heterogeneous, and its population is restricted to people with a history of periodontitis [F7]. The cleaning burden increases, but destruction is not inevitable — the actual situation has to be assessed by a dentist against the individual's oral conditions [F7].
