十二、F-Units（事实单元帐）

展开 29 条事实单元（来源#／confidence／basis／geo／period／caveat／逐字 span）

F1｜S3｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 收录随访 ≥20 年之前瞻研究，2026 发表 随访 ≥20 年的前瞻研究荟萃分析：对象为圆柱或锥形螺纹设计的钛质骨内牙科种植体；20 年存活率 93.0%（95% CI 91.6–94.1%），合并平均边缘骨丧失 1.11 mm（95% CI 0.55–1.68 mm）；GRADE 确定性中等。 span：「assess the 20-year survival rate and marginal bone loss (MBL) of titanium endosseous dental implants with cylindrical or conical screw-shaped designs」／「The 20-year implant survival rate was 93.0% (95% confidence interval 91.6-94.1%)」／「The pooled mean MBL was 1.11 mm (95% confidence interval 0.55-1.68 mm)」／「The certainty of the evidence (GRADE framework) was rated as moderate for both implant survival and MBL; however, this rating was limited by substantial heterogeneity」 caveat：群体层级估计，异质性高，不可推估个人结果；纳入研究仅 10 篇。

F2｜S3｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 同 F1 115 例种植体失败中仅 44 例明确报告失败原因，且生物性与机械性成因的分布几乎相等。 span：「The specific cause of failure was explicitly reported for 44 of the 115 implants and was almost equally distributed between biological and mechanical causes.」／「These reported 1857 implants (baseline) of which 1028 were followed up for ≥20 years, during which 115 implant failures were recorded.」 caveat：原因分布的分母只有明确报告原因的 44 例，不得写成整批 115 例失败或整个 20 年随访的成因分布；引用本条时须同时交代这个分母限制。

F3｜S4｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 资料库检索至 2024-06 伞状回顾将「吸烟与种植体失败」的关联评为 highly suggestive 等级。 span：「25 articles describing 35 associations were included in the study.」／「Highly suggestive evidence was established for the association between smoking and implant failure.」 caveat：观察性研究关联，非因果证明。

F4｜S4｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 同 F3 RCT 荟萃分析中属高确定性（GRADE）的三组关联，方向皆为前者与较高的种植体失败风险相关：turned 相较 anodized 表面、submerged 相较 nonsubmerged 愈合、长种植体并骨增生相较短种植体；观察性研究中列为 suggestive 的包含牙周条件受损者、骨质分类、负重方案、种植体长度等。 span：「turned versus anodized implants, submerged versus nonsubmerged implant healing, and bone augmentation with long implants versus short implants were associated with a higher risk of implant failure (high certainty evidence)」／「Suggestive evidence emerged for associations including periodontally compromised versus periodontally healthy patients」 caveat：关联方向依比较组定义，不可单独抽出某一项作绝对判断。方向不得删：原文明写这三组「were associated with a higher risk of implant failure」，只写「有高确定性证据的关联」而不写方向，会让读者无从得知哪一侧风险较高（其中「长种植体并行骨增生 vs 短种植体」的方向对「多做骨增生」不利，尤不得省略）。本文未引用该回顾结论段对 anodized 种植体的使用建议——器材选择属临床判断，且本文合规原则为不为任何材料或器材背书。

F5｜S4｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 同 F3 世代与病例对照研究之荟萃分析中，没有任何一组关联被评为 convincing 等级。 span：「None were graded as convincing.」 caveat：仅适用于该回顾纳入的 26 组观察性荟萃分析。

F6｜S2｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2017 World Workshop（2018 发表） 种植体周围炎＝发生于种植体周围组织、与菌斑相关的病理状况，特征为黏膜发炎并伴随支持骨的进行性丧失；临床上见发炎征象、探诊出血与／或流脓、探诊深度增加与／或黏膜缘退缩，并有影像上骨丧失。 span：「Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone.」／「Peri-implantitis sites exhibit clinical signs of inflammation, bleeding on probing, and/or suppuration, increased probing depths and/or recession of the mucosal margin in addition to radiographic bone loss.」 caveat：为病例定义，非个别诊断；诊断须由临床医师执行。

F7｜S2｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 同 F6 种植体周围黏膜炎主要临床特征为轻探即出血，可能并有红斑、肿胀或流脓；动物与人体实验研究有强证据指出菌斑为其病因。 span：「The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing. Erythema, swelling, and/or suppuration may also be present.」／「There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis.」 caveat：同 F6。

F8｜S2｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 同 F6 种植体周围健康以无红斑、无探诊出血、无肿胀、无流脓为特征；无法定义与健康相容的探诊深度区间；种植体周围健康可存在于骨支持已减少的种植体周围。 span：「Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; Peri-implant health can exist around implants with reduced bone support.」 caveat：同 F6。

F9｜S2｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 同 F6 共识报告建议：临床医师应在种植体支持的假牙完成后取得基线影像与探诊测量。 span：「It is recommended that the clinician obtain baseline radiographic and probing measurements following the completion of the implant-supported prosthesis.」 caveat：为临床作业建议，非病人自行操作事项。

F10｜S2｜confidence: medium｜basis: clinical_guideline｜geo: universal｜period: 同 F6 角化黏膜对种植体周围组织长期健康的影响证据不一致；但角化黏膜在病人舒适度与清洁难易度上可能有优势。 span：「The evidence is equivocal regarding the effect of keratinized mucosa on the long-term health of the peri-implant tissue. It appears, however, that keratinized mucosa may have advantages regarding patient comfort and ease of plaque removal.」 caveat：报告自述证据不一致，不可写成定论。

F11｜S16｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 2021 发表，纳入 28 篇（20 篇可量化） 拔牙后未辅助处置之自然愈合，依「测量方法×牙位」分层合并：临床测量下非臼齿区水平骨脊缩减平均 2.73 mm（95% CI 2.36–3.11）、中颊侧垂直向 1.71 mm（95% CI 1.30–2.12）；影像测量下非臼齿区水平缩减平均 2.54 mm（95% CI 1.97–3.11）、臼齿区水平缩减平均 3.61 mm（95% CI 3.24–3.98）。 span：「Pooled estimates revealed that mean horizontal, vertical mid-facial and mid-lingual ridge reduction assessed clinically in non-molar sites was 2.73 mm (95% CI: 2.36-3.11), 1.71 mm (95% CI: 1.30-2.12) and 1.44 mm (95% CI: 0.78-2.10), respectively.」／「Mean horizontal, vertical mid-facial and mid-lingual ridge reduction assessed radiographically in non-molar sites was 2.54 mm (95% CI: 1.97-3.11), 1.65 mm (95% CI: 0.42-2.88) and 0.87 mm (95% CI: 0.36-1.38), respectively.」／「Mean horizontal, vertical mid-facial and mid-lingual ridge reduction assessed radiographically in molar sites was 3.61 mm (95% CI: 3.24-3.98), 1.46 mm (95% CI: 0.73-2.20) and 1.20 mm (95% CI: 0.56-1.83), respectively.」 caveat：临床测量与影像测量为不同方法，数字不可互相替换。跨牙位比较只准在同一测量方法内进行（影像法：非臼齿 2.54 vs 臼齿 3.61）；以临床法的 2.73 对上影像法的 3.61 属跨方法拼接，不成立。

F12｜S16｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 同 F11 拔牙窝未辅助愈合所发生的牙槽骨吸收量随牙位类型而异。 span：「A variable amount of alveolar bone resorption occurs after unassisted socket healing depending on tooth type.」 caveat：仅描述变异存在，未给个别预测值。

F13｜S6｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026 发表，纳入 53 篇 骨移植材料分四类：自体骨、同种异体骨、异种骨、人工合成材；对何者较优仍无共识，且因高质量证据不足无法下定论。 span：「Fifty-three studies were included.」／「These procedures utilize bone grafting materials of which there are four types, namely, autogenous, allograft, xenograft, and alloplastic grafts. However, there is still no consensus on which material is superior.」／「due to the lack of high-quality evidence in this review, definitive conclusions on which material is superior was not possible」 caveat：各研究方法差异大，无法直接比较结果。

F14｜S6｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 同 F13 缺牙后的自然生理性骨吸收常导致可用骨量不足以把种植体放在修复需要的位置；因而发展出引导骨再生（GBR）、上颌窦增高（SA）与牙槽脊保存（ARP）等骨再生术式。 span：「The natural physiological bone resorption following tooth loss often results in reduced bone volume to place dental implants in a restoratively driven position. Bone regeneration procedures such as guided bone regeneration (GBR), sinus augmentation (SA), and alveolar ridge preservation (ARP) have therefore been developed to promote new bone formation.」 caveat：术式适用与否为个案判断。

F15｜S5｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 2026 发表，纳入 100 篇（PROSPERO CRD420251052858） 上颌骨增生术式并发症合并发生率：上颌窦增高 7.98%（95% CI 2.78–15.55）、引导骨再生 26.44%（95% CI 13.06–42.52）、onlay 骨移植 19.61%（95% CI 13.94–25.99）、混合术式 20.10%（95% CI 13.92–27.09）；较常见类型为膜或移植材暴露、伤口裂开与感染。 span：「Of the 2,266 articles reviewed, 100 were selected.」／「Pooled complication rates were: 7.98% (95% CI: 2.78 - 15.55) for sinus lift, 26.44% (95% CI: 13.06 - 42.52) for guided bone regeneration, 19.61% (95% CI: 13.94 - 25.99) for onlay grafting, and 20.10% (95% CI: 13.92 - 27.09) for mixed techniques. The most frequent complications were membrane or graft exposure, wound dehiscence, and infection.」／「The analysis focused on postoperative complications in maxillary bone regeneration techniques.」 caveat：部位限定＝上颌（原文两处明写 maxillary），不得外推至下颌骨增生；术式限定＝上颌窦增高／引导骨再生／onlay 骨移植／混合术式四种，未涵盖牙槽脊保存（ARP），本条不得与含 ARP 的术式清单并句使用。置信区间宽，异质性大。

F16｜S7｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 2025-12 发表，11 篇 RCT（IIP 353 人／ARP 348 人） 作者结论：即刻种植牙（IIP）可达到与牙槽脊保存（ARP）相当的美观结果与种植体成功情形，但可能有较高的术后并发症发生率与较大的边缘骨变化。结果段对应数据：美观分数（PES）MD −0.05（95% CI −0.52 至 0.43）与种植体失败 OR 2.09（95% CI 0.98 至 4.44）两项未观察到统计显著差异；术后并发症一项在 IIP 组较高（p < 0.05）。 span：「Eleven RCTs were included, involving 353 patients in the IIP group and 348 patients in the ARP group.」／「no statistical differences were observed regarding PES (MD = -0.05, 95% CI = -0.52 to 0.43) or implant failure (OR = 2.09, 95% CI = 0.98 to 4.44)」／「both groups achieved similar outcomes in terms of horizontal width change, facial gingival margin change, and patient-reported satisfaction (P > .05), except for a higher incidence of postoperative complications observed in the IIP group (p < 0.05)」／「the IIP protocol can achieve comparable esthetic outcomes and implant success as the ARP protocol; however, there may be a higher incidence of postoperative complications and MBL alterations.」 caveat：作者自述受研究局限所限，需更长期 RCT 验证。「相当」的统计意涵限定：结论句的 comparable esthetic outcomes and implant success，对应的是 PES 与种植体失败两项「未达统计显著差异」；其中种植体失败的点估计 OR 2.09 偏向即刻种植牙较高、95% CI 上限接近 4.5，且仅纳入 11 篇试验（353 人／348 人），检定力有限——不得把「未达统计显著」改写成「两者失败风险相当／一样安全」（absence of evidence ≠ evidence of absence）。对冲词限定：术后并发症在 CONCLUSION 段写为「may be」，在 RESULTS 段则为 p < 0.05 的组间差异；正文若写成断言，须引 RESULTS 段之 span 并标明为该回顾之结果，不得单凭 CONCLUSION 句去对冲词。

F17｜S8｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-06 发表，7 篇 RCT、n=589 术前预防性使用口服类固醇或非类固醇抗发炎药物的系统综述，主要结果指标为术后疼痛、水肿、牙关紧闭、不适与救援用药；因给药方案与结果指标异质性高，无法就哪一种术前用药在效果与安全性上较佳得出定论。 span：「The primary outcomes were postoperative pain, edema, trismus, discomfort, and use of rescue medication.」／「Seven RCTs (n = 589 patients)」／「Owing to the heterogeneity in protocols, drug regimens, and outcome measures, definitive conclusions regarding the most effective and safest preemptive agents could not be drawn.」 caveat：本文刻意不引用该回顾中的药名与剂量（处方行为，且对大众卫教不宜列出用药指示）。

F18｜S9｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-01 发表，10 篇随机安慰剂对照／对照组试验、合并约 1,950 名参与者 涵盖各类侵入性牙科处置（含种植体植入与拔牙）的随机效应荟萃分析：介入定义为全身性抗生素与／或局部抗菌剂预防，合并终点为早期处置相关感染结果与／或菌血症相关终点；预防性抗菌用药在主要合并终点未显示统计上显著的整体降低（MD −0.12，95% CI −0.31 至 0.07；I² 约 99%）；种植牙试验本身事件率低，未一致显示常规预防用药具临床上有意义的优越性。 span：「Prophylactic antimicrobials are frequently administered before invasive dental procedures (including implant placement and extractions)」／「Included studies evaluated perioperative prophylaxis (systemic antibiotics and/or local antiseptic prophylaxis) versus placebo or no prophylaxis in invasive dental procedures.」／「Outcomes were harmonized across studies as early procedure-related infectious outcomes and/or bacteremia-related endpoints」／「Across all invasive dental procedures (~1,950 participants pooled), prophylaxis did not demonstrate a statistically significant overall reduction in the primary pooled endpoint (MD -0.12, 95%CI -0.31 to 0.07; random-effects; I² ≈ 99%)」／「Individual trials showed marked reductions in post-extraction bacteremia surrogates with chlorhexidine mouthwash prophylaxis」／「Implant trials reported low event rates and did not consistently demonstrate clinically meaningful superiority of routine prophylaxis.」／「Funnel plot inspection suggested possible small-study effects influenced by outliers, but interpretation was constrained by extreme between-study heterogeneity.」 metadata 实测（2026-08-06 efetch，HTTP:200）：PubMed 对本篇登录的 PublicationType 为 `['Journal Article', 'Review']`——未登录 Systematic Review 或 Meta-Analysis（对照：S10／PMID 32591710 登录为 `['Journal Article', 'Meta-Analysis', 'Systematic Review']`；S5／PMID 41077306 登录为 `['Journal Article', 'Systematic Review', 'Meta-Analysis']`）。 caveat：I² 约 99% 属极高异质性，作者自述解读受此限制，且 funnel plot 显示可能存在小研究效应。效应量尺度限定：本条主要合并终点以均差（MD −0.12）合并，与 S10 以风险比（RR 0.47）合并种植体失败属不同尺度，两数字不可互换算、不可直接比大小。文献型别限定：与 S10 并列时须揭露上述 PublicationType 差异，不得迳称两者为同层级的「两派」。引用本条时三项限定不得省略：(a) 介入含局部抗菌剂（个别试验包含 chlorhexidine 漱口水），不可简称为「口服抗生素无效」；(b) 终点含菌血症代理指标，与「种植体失败」不是同一件事；(c) 终点跨处置类型合并，非种植牙专属结论。与种植牙专属回顾（S10）的差异来自处置范围／介入定义／终点，不是年份演进，不可写成「新研究推翻旧研究」。

F19｜S9｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 同 F18 微生物学证据显示单剂预防性用药可造成短期生态扰动与口腔抗药性菌丛的选汰。 span：「microbiological evidence indicates that single-dose prophylaxis can promote short-term ecological disturbance and selection of resistant oral flora.」 caveat：来自实验性研究的推论，非临床结果指标。

F20｜S10｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2020-06 发表，检索至 2018-02，14 篇文献 预防性抗生素与种植体失败风险降低相关。介入定义（原文）＝「种植体手术前给予，以及术前给予并持续至术后即刻（PIFS）」的预防性抗生素；纳入的种植体中 5,334 支使用术前抗生素、82 支使用 PIFS、3,862 支未使用抗生素。整体风险比 RR 0.47（95% CI 0.39–0.58），NNT 35（95% CI 26.3–48.2）；作者结论写为「给予预防性抗生素降低了种植体失败风险」，并指出仍需建立标准化用药疗程。 span：「To assess the literature on the efficacy of prophylactic antibiotics prescribed prior to and immediately following implant surgery (PIFS).」／「Fourteen publications were collected」／「5,334 implants were placed with pre-operative antibiotics, 82 implants with antibiotics PIFS and 3,862 placed with no antibiotics」／「The overall risk ratio (RR) was 0.47 (95% CI 0.39-0.58)」／「The number needed to treat (NNT) was 35 (95% CI 26.3-48.2).」／「Administering prophylactic antibiotics reduced the risk of implant failures.」／「Further investigations are recommended to establish a standardised protocol for the proper use of antibiotic regimen.」 caveat：与 F18 结论方向不同，年份、纳入条件与终点定义皆不同，需并列呈现而非择一。介入定义限定：RR 0.47 为含 PIFS 臂在内的 overall RR，原文 AIM 与 CONCLUSION 均未把介入窄化为「仅术前」——不得写成「术前给予的 RR」；正确写法为「术前给予以及术前给予并持续至术后即刻（PIFS）」。PIFS 臂仅 82 支种植体，占比小，但既属合并范围即须揭露。效应量尺度限定：本条为风险比（RR），与 F18 的均差（MD）不同尺度，不可互换算或直接比大小。metadata 实测（2026-08-06 efetch，HTTP:200）：PublicationType＝`['Journal Article', 'Meta-Analysis', 'Systematic Review']`。

F21｜S1｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2015 EAO 第 4 届共识会议 EAO 第 4 届共识会议工作组将抗生素预防在种植牙手术中的角色、种植体周围炎、病人回报结果（PROMs）与健康经济列为种植牙病人的关键议题，并指出抗生素预防属长期存在对立意见的领域。 span：「This included areas where conflicting opinions exists since long or recently has been expressed, like the role of antibiotic prophylaxis in dental implant surgery and peri-implantitis.」／「Also areas with growing interest and concern such as patient-reported outcome measures (PROMs) and health-economy was included in this review.」 caveat：2015 年共识，后续证据已更新（见 F18、F20）。

F22｜S11｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 检索 2014-01 至 2024-05，纳入 5 篇 对象限无牙上颌（edentulous maxilla）病人、比较即刻／早期／延迟负重的前瞻研究系统综述（纳入 5 篇，排除颧骨种植体）中，临床端结果指标（ClinROs）无标准化做法，造成报告结果高度异质。 span：「comparing immediate, early, and delayed implant loading protocols in edentulous maxilla patients receiving implant-supported prostheses」／「Zygomatic implants were excluded.」／「Five studies were included, of which four compared immediate versus delayed loading and one study compared immediate versus early loading.」／「ClinROs showed no standardized approach, creating significant heterogeneity in the reported outcomes.」 caveat：仅纳入 5 篇研究，对象限无牙上颌，排除颧骨种植体。人群限定不得删：引用本条时必须同时写出「无牙上颌」，不得写成「比较不同负重时机的前瞻研究」这种通称，否则会被读成整个负重时机领域的通则（与 F23 人群限定同一处理标准）。本条属研究方法学层级（各研究「用什么指标测」不统一），不等于临床上「疗程时程没有标准」；即刻／早期／延迟负重本身在文献中有既定的分类定义，不得以本条推论成「多久没有标准答案」。

F23｜S12｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2021-10 发表，40 篇文章／35 个队列研究 就以种植体支持的单颗或短跨距重建、以及覆盖义齿而言，无强证据支持种植体植入或负重的时机会影响病人的不适感、对功能或美观的满意度，或整体治疗满意度。 span：「finally 40 articles, representing 35 cohort studies, were included.」／「There is no strong evidence to support that the time for implant placement or loading of implant-supported single or short-span reconstructions or overdentures influence patients´ discomfort, satisfaction with function or esthetics or overall satisfaction with the implant treatment.」 caveat：多数纳入研究质量评估有疑虑（some concerns）。人群限定不得删：本条只涵盖单颗／短跨距重建与覆盖义齿，不是对所有种植牙治疗的全称否定；全牙弓固定式重建的方向不同，见 F24。本条亦为「病人感受」结论，不得改写成「疗程长度／时程没有标准」。

F24｜S12｜confidence: low｜basis: peer_reviewed｜geo: universal｜period: 同 F23 无牙病人以种植体支持全牙弓固定式重建者，短期内对即刻负重的满意度较高，但该差异在治疗后一年时不明显。 span：「There is some evidence that studies including edentulous patients rehabilitated with implant-supported full-arch FDPs demonstrate more satisfied patients with immediate than for the early or delayed loaded implant reconstructions after short time, but the difference is not clear one year after treatment.」 caveat：原文自述为「some evidence」，证据强度低。

F25｜S13｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 检索至 2023-07，纳入 12 篇 在重度牙周病（无望或预后可疑牙齿）情境下，种植体维护成本加上并发症处置成本，似乎超过治疗与维护牙周条件受损牙齿的成本。该回顾纳入 12 篇，其中 9 篇谈保留牙齿的成本效益、3 篇谈以种植体取代牙周条件受损牙齿。 span：「Twelve articles were included, of which nine articles discussed the cost-effectiveness of preserving teeth in severe periodontal disease and three articles discussed the effectiveness of implants that replaced the periodontally compromised teeth.」／「implant maintenance cost as well as the cost associated with treating implant complications should be considered. This cost seems to surpass the cost of treatment and maintenance of periodontally compromised teeth.」 caveat：限重度牙周病情境；为相对成本结论，未涉任何金额或币别，不可外推至其他缺牙情境。研究设计限定：9 篇＋3 篇为两组互不对照文献的间接并置，不是同一批病人的头对头比较，引用时不得写成「比较了 A 与 B」。适用性限定：成本效益结论高度依赖各国医疗体系与收费结构，本篇 geo_scope 为 global，不得用来回答任一地的实际费用或划算与否。

F26｜S13｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 同 F25 种植体为有效的缺牙替代选项，但会出现并发症、需要严格维护，并非装上后即不需再处理。 span：「Implants are an effective choice to replace missing teeth; however, these are not permanent, present complications, and require strict maintenance.」 caveat：为回顾作者之总结陈述。来源情境限定（与 F25 同一篇 S13）：该回顾的对象为重度牙周病（无望或预后可疑牙齿）患者，主题为成本效益；本条是它 CONCLUSIONS 的开场总结，不是一份针对全体种植牙病人的预后研究。引用于 TL;DR 或 FAQ 等高抽取率位置时，须同时揭露其来源情境，并以 F1（≥20 年前瞻研究荟萃分析、GRADE 中等）作为长期结果的主锚；本条只作佐证，不得单独承载对全体种植牙病人的预后宣告。

F27｜S14｜confidence: low｜basis: peer_reviewed｜geo: universal｜period: 2012 发表，质性研究 n=10 质性研究（grounded theory）记录到：治疗前的把关因素包括费用与看牙焦虑；牙医师的意见与建议是决策过程中决定性的部分，对牙医师与团队的信任是接受治疗与整体治疗经验的关键。 span：「Ten informants participated in the study, all of whom were treated with implant-supported fixed dentures during the past year.」／「gatekeeping factors before treatment, such as cost and dental anxiety, were noted. The dentist's opinion and suggestions were the most decisive part of the decision-making process, and trust in the dentist and dental team was crucial in the decision to undergo treatment」 caveat：10 位受访者之质性设计，不可推论比例或代表性。

F28｜S15｜confidence: low｜basis: peer_reviewed｜geo: universal｜period: 2024 发表，随机分组比较 n=32（住院口腔颌面手术病人） 软质混合饮食（SBD）组较全流质饮食（SFD）组有较高的摄食量数值（63.2% vs. 51.0%）；原文在摄食量这一项未报告 p 值（同段的饮食满意度 P<0.0001 有报告）。 span：「Thirty-two patients were randomized into two groups: sixteen received SFD and sixteen received SBD.」／「The SBD group had higher dietary intake (63.2% vs. 51.0%) and greater diet satisfaction (80.6 vs. 48.1, P < 0.0001) compared to SFD group.」 caveat：样本数 32、单一情境（住院口腔颌面手术），非门诊种植牙病人研究，亦非任何饮品（含咖啡）之专门研究；本文仅作背景使用，不外推为种植牙术后饮食指示。统计限定：摄食量差异未报告统计显著性，只能叙述为数值差异，不得写成已证实的组间差异。设计描述限定：PubMed PublicationType 仅标示 `Journal Article`（标题自述 comparative study，摘要 METHODS 写 randomized into two groups），本文因此描述为「随机分组比较研究」而不写 RCT。

F29｜S12｜confidence: high｜basis: peer_reviewed｜geo: universal｜period: 同 F23 种植牙的疗程方案通常包含等待拔牙窝愈合与种植体骨整合的期间。 span：「Protocols for implant dentistry, most frequently include periods until healing of the extraction sockets and osseointegration of the implant.」 caveat：为描述性陈述，未给定任何等待天数。

FAQ

Q1. 种植牙可以用多久？
在随访 20 年以上的前瞻研究荟萃分析中，20 年种植体存活率为 93.0%（95% CI 91.6–94.1%），合并平均边缘骨丧失 1.11 mm，证据确定性评为中等且异质性高 [F1]。这是群体统计，不能推估个人结果。另一篇以重度牙周病患者为对象的成本效益回顾则总结：种植体并非永久、会出现并发症、需要严格维护 [F26]。
Q1. インプラントはどれくらいもちますか？ — 20 年以上追跡した前向き研究のメタアナリシスでは、20 年のインプラント生存率は 93.0%（95% CI 91.6–94.1%）、統合された平均辺縁骨吸収は 1.11 mm であり、エビデンスの確実性は中等度、異質性は高いと評価されています [F1]。これは集団の統計であって、個人の結果を推定することはできません。また、重度歯周病の患者を対象とした費用対効果のレビューは、インプラントは永久的ではなく、合併症が生じ、厳格なメインテナンスを必要とすると総括しています [F26]。
Q1. How long does an implant last? — In the meta-analysis of prospective studies with more than 20 years of follow-up, the 20-year implant survival rate was 93.0% (95% CI 91.6–94.1%) and the pooled mean marginal bone loss was 1.11 mm, with the certainty of evidence rated moderate and heterogeneity high [F1]. These are population statistics and cannot be used to estimate an individual outcome. A separate cost-effectiveness review, whose subjects were patients with severe periodontal disease, summarises instead that implants are not permanent, present complications and require strict maintenance [F26].
Q2. 骨头不够就不能种植牙吗？
缺牙后的生理性骨吸收常使可用骨量不足，因此才发展出引导骨再生、上颌窦增高与牙槽脊保存等骨增生术式 [F14]；移植材料分四类，文献对何者较优尚无共识 [F13]。骨增生本身带有并发症：一篇聚焦上颌骨增生的回顾量化了上颌窦增高、引导骨再生、onlay 骨移植与混合术式的并发症合并发生率（该回顾未涵盖牙槽脊保存，数字亦不外推至下颌）[F15]。是否适用须由牙医师评估。
Q2. 骨が足りなければインプラントはできないのですか？ — 歯を失った後の生理的な骨吸収により利用できる骨量が不足することが多く、そのため骨誘導再生、上顎洞挙上、歯槽堤保存などの骨造成術式が発展してきました [F14]。移植材料は四種類に分かれ、どれが優れているかについて文献に合意はありません [F13]。骨造成そのものにも合併症があります。上顎の骨造成に焦点を当てたレビューが、上顎洞挙上、骨誘導再生、onlay 骨移植、混合術式の合併症の統合発生率を定量化しています（当該レビューは歯槽堤保存を含まず、数値を下顎に外挿することもできません）[F15]。適用できるかどうかは歯科医師の評価が必要です。
Q2. Does insufficient bone mean an implant is impossible? — The physiological bone resorption that follows tooth loss often leaves the available bone volume insufficient, which is why bone augmentation techniques such as guided bone regeneration, sinus augmentation and alveolar ridge preservation were developed [F14]; graft materials fall into four types and the literature has no consensus on which is superior [F13]. Bone augmentation itself carries complications: a review focused on the maxilla quantified the pooled complication rates of sinus lift, guided bone regeneration, onlay grafting and mixed techniques (that review does not cover alveolar ridge preservation, and its figures are not extrapolated to the mandible) [F15]. Whether it applies in a given case must be assessed by a dentist.
Q3. 种植牙一定要吃抗生素吗？
这是国际文献中长期存在争议的题目 [F21]。两份回顾问的其实不是同一件事：2020 年那篇限于种植体植入手术、终点为种植体失败，其介入为术前给予以及术前给予并持续至术后即刻（PIFS）的预防性抗生素，整体风险比 RR 0.47（NNT 35）[F20]；2026 年那篇涵盖各类侵入性牙科处置，介入定义为全身性抗生素与／或局部抗菌剂（含 chlorhexidine 漱口水），合并终点为早期感染与／或菌血症相关的代理指标，未显示统计上显著的整体降低 [F18]。两者的效应量尺度也不同（前者为风险比 RR、后者为均差 MD），不能直接比大小；PubMed 对后者登录的文献型别亦仅为 `Journal Article, Review` [F18][F20]。后者也提醒单剂预防用药可能扰动口腔菌相与选汰抗药性菌株 [F19]。用药以主治牙医师处方为准。
Q3. インプラントでは必ず抗菌薬を飲まなければいけませんか？ — これは国際的な文献の中で長く議論が続いているテーマです [F21]。二つのレビューが問うているのは、実は同じことではありません。2020 年の論文はインプラント埋入手術に限られ、エンドポイントはインプラントの失敗で、その介入は術前投与および術前投与に加えて術直後まで継続する投与（PIFS）の予防的抗菌薬であり、全体のリスク比は RR 0.47（NNT 35）です [F20]。2026 年の論文は各種の侵襲的な歯科処置を対象とし、介入の定義は全身性の抗菌薬および／または局所の抗菌薬（chlorhexidine の洗口液を含む）で、統合エンドポイントは早期感染および／または菌血症関連の代替指標であり、統計学的に有意な全体的低下は示されていません [F18]。両者の効果量の尺度も異なり（前者はリスク比 RR、後者は平均差 MD）、そのまま大小を比べることはできません。PubMed が後者に登録した文献タイプも `Journal Article, Review` のみです [F18][F20]。後者は、単回投与の予防投与が口腔細菌叢を攪乱し耐性菌を選択しうることも注意喚起しています [F19]。薬の使用は主治の歯科医師の処方によります。
Q3. Do antibiotics always have to be taken for an implant? — This is a long-standing point of controversy in the international literature [F21]. The two reviews are not in fact asking the same question: the 2020 one is limited to implant placement surgery with implant failure as its endpoint, its intervention being prophylactic antibiotics given pre-operatively and given pre-operatively with continuation immediately post-operatively (PIFS), with an overall risk ratio of RR 0.47 (NNT 35) [F20]; the 2026 one covers invasive dental procedures of all kinds, defines its intervention as systemic antibiotics and/or local antiseptics (including chlorhexidine mouthwash), and pools a surrogate endpoint of early infection and/or bacteremia, showing no statistically significant overall reduction [F18]. The two also use different effect-size scales (a risk ratio RR for the former, a mean difference MD for the latter) and cannot be compared directly for magnitude; PubMed also registers the latter's publication type merely as `Journal Article, Review` [F18][F20]. The latter further cautions that single-dose prophylaxis may disturb the oral flora and select for resistant strains [F19]. Medication follows the prescription of the treating dentist.
