  • F1｜来源#1｜confidence: high（对「此议题有争议」此一叙述）｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 正畸的理想治疗时机依现存异常的类型与严重程度而有争议地被讨论，特别是在效率、病人负担与治疗投入面向。｜span: "Ideal treatment timing in orthodontics is controversially discussed depending on the type and extent of the dysgnathia and malocclusion present, especially with regard to efficiency, patient burden and treatment efforts"｜caveat: 出自指引摘要之目的段落；本站仅取回 PubMed 摘要（PMID 35713671），指引正文未取回，不对全文作逐字引用。
  • F2｜来源#1｜confidence: high（对方法学规模此一事实）｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 该指引自超过 11,000 笔筛选来源中纳入 309 篇研究并逐篇评读，由 21 个德国学术团体与组织的代表以名义共识程序达成 19 条实证陈述与建议。｜span: "A total of 309 studies of over 11,000 sources screened were identified to be eligible for inclusion and critically appraised for study quality and risk-of-bias."／"Elected delegates of in total 21 German scientific societies and organizations agreed upon a total of 19 evidence-based statements and recommendations based on a nominal consensus process."｜caveat: 为德国学会制定之国家级指引，其共识程序反映德国专业社群立场；本文引用其实证陈述，不主张其对任一国家具法规效力。
  • F3｜来源#1｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 多数错颌畸形在早期混合齿列、晚期混合齿列与恒牙列时期皆可被有效治疗。｜span: "most malocclusions can be effectively treated both in the early, late mixed, and permanent dentition"｜caveat: 原句前有 Although 之让步结构，后接依分类而异的例外建议（见 F4、F5、F6），不可单独解读为「时机不重要」。
  • F4｜来源#1｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 明显的骨性或齿性第 II 类异常可及早开始治疗以降低前牙外伤风险；中度第 II 类异常则宜于青春期生长高峰之前或期间进行。｜span: "therapy of a pronounced skeletal or dental class II anomaly can be started early to reduce the risk of dental anterior tooth trauma, whereas in a moderate class II anomaly, therapy can preferably be carried out before or during the pubertal growth peak"｜caveat: 原文措辞为 can be／can preferably be，属建议而非强制；严重度分级（pronounced／moderate）须由临床判定。
  • F5｜来源#1｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 骨性或齿性第 III 类异常应及早开始治疗，因为这同时降低日后为正畸此异常而需要手术的机会。｜span: "Therapy of a skeletal or dental class III anomaly should be started early, as this also reduces the need for later surgery to correct the anomaly."｜caveat: 原句为降低「需要」（need）之措辞，非「不会需要」；本文据此仅陈述手术是部分个案路径中存在的选项，未推估任何比例。
  • F6｜来源#1｜confidence: high｜basis: clinical_guideline｜geo: universal｜period: 2022-07｜claim: 明显的骨性或齿性横向异常应及早于上颌开始治疗，以利用年轻病人上颌结构的高度适应性。｜span: "The treatment of a pronounced skeletal or dental transverse anomaly should be started early in the upper jaw in order to utilize the high adaptivity of the maxillary structures in young patients."｜caveat: 适用对象为明显（pronounced）之横向异常；本文未由此推导任何装置品牌或具体疗程长度。
  • F7｜来源#2｜confidence: medium（点估计 high、外推 low）｜basis: peer_reviewed｜geo: universal｜period: 2020｜claim: 全球儿童与青少年错颌畸形的汇总患病率为 56%（95% 置信区间 11 至 99），未见性别差异；非洲 81%、欧洲 72%、美洲 53%、亚洲 48%。｜span: "77 studies were included in this review."／"The worldwide prevalence of malocclusion was 56% (95% CI: 11-99), without differences in gender. The highest prevalence was in Africa (81%) and Europe (72%), followed by America (53%) and Asia (48%)."｜caveat: 纳入 77 篇研究、对象为儿童与青少年；置信区间宽达 11 至 99 显示研究间异质性极大，不得当作任一地区或任一个人的风险估计，亦不代表这些人都需要治疗。
  • F8｜来源#2｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2020｜claim: 错颌畸形的整体患病率自乳牙列到恒牙列未改变（同为 54%）；交叉咬合与齿间缝于恒牙列时期下降，剪刀咬与齿列拥挤则上升。｜span: "The malocclusion prevalence score did not change from primary to permanent dentition with a common score of 54%."／"traits such as cross-bite and diastema reduced their prevalence during permanent dentition, while scissor-bite and dental crowding increased their scores"｜caveat: 为跨研究汇总的人群层级变化，非个人牙列变化的预测；本文未由此推导任何个别治疗时机。
  • F9｜来源#3｜confidence: low（原文为可能性措辞）｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 儿童前牙错咬若未治疗，可能导致咬合功能障碍、颅颜生长受影响，以及长期的牙周或颞下颌并发症。｜span: "Anterior crossbite in children is a common malocclusion that, if left untreated, may lead to occlusal dysfunction, impaired craniofacial growth, and long-term periodontal or temporomandibular complications"｜caveat: 出自该研究背景段落之可能性陈述（may lead），非其统计结果；本文不得以此构成任何急迫性诉求。
  • F10｜来源#3｜confidence: high（对纳入规模与分层此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 该荟萃分析纳入 21 篇随机对照试验、854 名 6 至 12 岁儿童，其中 18 篇针对骨性、2 篇针对功能性、1 篇针对齿性前牙错咬。｜span: "Only randomized controlled clinical trials (RCTs) focusing on children aged 6-12 years who received orthodontic treatment for anterior crossbite correction were considered eligible."／"A total of 21 RCTs involving 854 participants were included, comprising 18 studies on skeletal, two on functional, and one on dental anterior crossbite."｜caveat: 对象限 6 至 12 岁儿童；齿性与功能性各仅 1 至 2 篇，该两类的证据基础明显薄于骨性。
  • F11｜来源#3｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 口内非骨锚式装置适用于齿性与功能性错咬及轻度骨性差异；真骨性前牙错咬则以口外牵引罩合并快速上颌扩张（FM-RME）为达成显著骨骼正畸较可靠的方式，其汇总估计为 ANB 增加 3.54 度、SNA 增加 1.37 度、SNB 减少 2.14 度。｜span: "Intraoral appliances are appropriate for dental and functional crossbites and mild skeletal discrepancies, whereas FM-RME remains the most reliable modality for achieving significant skeletal correction in true skeletal anterior crossbite cases."／"pooled estimates showing significant increases in ANB (MD = 3.54°) and SNA (MD = 1.37°), along with a reduction in SNB (MD = -2.14°), although substantial heterogeneity was observed across studies"｜caveat: 研究间异质性大；此为人群层级的角度变化，非个人可预期之结果，亦不构成装置推荐。
  • F12｜来源#3｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 骨锚式牵引罩相较传统牙支撑式牵引罩，在整体矢状向正畸上未显示临床上有意义的优势（ANB 平均差 0.07 度），仅在上颌前移上有小幅额外改善（SNA 平均差 0.59 度）。｜span: "Skeletally anchored facemask therapy did not demonstrate a clinically meaningful advantage in overall sagittal correction compared with conventional tooth-borne facemask therapy (ANB MD = 0.07°), although a small additional improvement in maxillary advancement was noted (SNA MD = 0.59°)."｜caveat: 适用情境限前牙错咬之牵引罩治疗；不可外推为「所有骨锚式装置皆无额外效益」。
  • F13｜来源#3｜confidence: high（对作者自评此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 该分析的整体证据确定性自极低到中等，且各试验在装置设计、治疗流程、随访长度与结果评估方法上差异相当大。｜span: "The overall certainty of evidence ranged from very low to moderate."／"Considerable variability existed across trials in terms of appliance design, treatment protocols, follow-up duration, and outcome assessment methods."｜caveat: 本条用于标示证据强度，不用于支持任何治疗方式的优劣结论。本站以 efetch retmode=xml 实查该篇 PublicationType 为 Journal Article／Review，未被 PubMed 索引为 Systematic Review 或 Meta-Analysis；本文转述其自述之研究设计（系统综述与荟萃分析）时一并揭露此差异，读者宜据此降权。
  • F14｜来源#4｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 用于正畸骨性第 III 类错颌畸形的口外装置体积大、美观不佳且高度依赖病人配合度，因而口内替代方案受到关注。｜span: "Extra-oral appliances used for correcting skeletal Class III malocclusion are often bulky, unaesthetic, and heavily reliant on patient compliance, which can negatively affect treatment outcomes, particularly in growing patients."｜caveat: 出自该回顾背景段落之临床脉络陈述，非其统计结果。
  • F15｜来源#4｜confidence: low（作者自评证据低至极低，见 F16）｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 该回顾纳入 8 篇随机对照试验、336 名生长期病人，其中仅 2 篇适合量化合并；在评估的口内非骨锚式装置中，下颌清透板式颌间牵引（LCP-IMT）与反式 Twin Block 于矢状向的骨骼改善表现较明显。｜span: "A total of eight RCTs involving 336 growing patients met the inclusion criteria, although only two studies were suitable for quantitative meta-analysis."／"LCP-IMT and reverse twin block (RTB) appliances demonstrated the most favorable skeletal improvements in the sagittal dimension."｜caveat: 8 篇中仅 2 篇进入荟萃分析，其余为叙述性汇整；不可读为装置排名或推荐。
  • F16｜来源#4｜confidence: high（对作者自评此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026-06｜claim: 该回顾的整体证据强度介于低与极低之间，原因为方法学限制、样本数小与纳入研究间的异质性。｜span: "the overall strength of evidence was between low and very low due to methodological limitations, small sample sizes, and heterogeneity among the included studies, highlighting the need for further high-quality research"｜caveat: 本条用于标示证据强度，不用于支持任何装置的优劣结论。本站以 efetch retmode=xml 实查该篇 PublicationType 为 Journal Article／Review，未被 PubMed 索引为 Systematic Review 或 Meta-Analysis；本文转述其自述之研究设计（系统综述与荟萃分析）时一并揭露此差异，读者宜据此降权。
  • F17｜来源#5｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-05｜claim: 因下颌后缩造成的第 II 类错颌畸形常以功能性矫治器处置，但可移除式与固定式之间的比较效果仍不确定。｜span: "Class II malocclusion due to mandibular retrusion is commonly managed with functional appliances, yet the comparative effectiveness of removable and fixed modalities remains uncertain."｜caveat: 出自背景段落；第 II 类错颌畸形并非皆因下颌后缩，本文未将两者等同。
  • F18｜来源#5｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-05｜claim: 该回顾纳入 9 篇比较性临床研究、共 377 位参与者（188 位使用 Forsus 疲劳阻抗装置、189 位使用 Twin Block），两类装置皆能改善覆盖、覆咬与臼齿关系；Twin Block 的骨骼贡献较强，Forsus 则主要透过牙槽层面的代偿（下颌门齿唇倾）达成。｜span: "The included studies comprised predominantly nonrandomized designs and together represented 377 participants, with 188 treated using FFRD and 189 using TB."／"TB provides a stronger skeletal effect, whereas FFRD achieves correction predominantly through dental adaptation"｜caveat: 纳入研究以非随机设计为主；为质性综合（qualitative synthesis），未做荟萃分析；气道相关结果仅少数研究报告且不一致，本文未引用。本站以 efetch retmode=xml 实查该篇 PublicationType 为 Journal Article／Review，未被 PubMed 索引为 Systematic Review 或 Meta-Analysis；本文转述其自述之研究设计（系统综述与荟萃分析）时一并揭露此差异，读者宜据此降权。
  • F19｜来源#6｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-04-01｜claim: 清透矫治器合并下颌前导（CAMA）作为正畸第 II 类错颌畸形的美观替代方案，其相较传统功能性矫治器的效果仍有争论。｜span: "Clear Aligner Mandibular Advancement (CAMA) has emerged as an esthetic alternative for correcting Class II malocclusion, yet its efficacy compared to traditional functional appliances remains debated."｜caveat: 出自背景段落之议题陈述。
  • F20｜来源#6｜confidence: low（作者自评证据以回溯性为主，见 F21）｜basis: peer_reviewed｜geo: universal｜period: 2026-04-01｜claim: 该荟萃分析纳入 9 篇研究（1 篇随机试验、8 篇非随机研究）、465 位参与者，对象为生长期之骨性第 II 类病人；CAMA 与传统 Twin Block 在骨骼角度与垂直向无统计显著差异，覆盖减少量的差异达统计显著但临床上极小（平均差 -0.46 公厘），下颌门齿唇倾则明显较少（平均差 -0.90 度）。｜span: "in growing patients with skeletal Class II malocclusion"／"Nine studies (1 RCT, 8 NRSIs) comprising 465 participants were included."／"the CAMA group demonstrated a statistically significant, though clinically minimal, greater overjet reduction compared to TB (MD = -0.46 mm, P = 0.03)"／"CAMA exhibited significantly less lower incisor proclination compared to TB (MD = -0.90°, P = 0.0002)"｜caveat: 对象限生长期第 II 类病人；差异虽具统计显著性，原文自评临床意义极小，不可转述为疗效优势。
  • F21｜来源#6｜confidence: high（对作者自评此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026-04-01｜claim: 该研究指出现有证据以回溯性研究为主，其发现应审慎解读，并需未来严谨的随机对照试验确认。｜span: "Based on the currently available evidence, which is predominantly retrospective"／"these findings should be interpreted with caution and confirmed by future rigorous randomized controlled trials"｜caveat: 本条用于标示证据强度。
  • F22｜来源#7｜confidence: high（对纳入规模与偏倚评估此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026｜claim: 该系统综述自 196 篇初筛、55 篇全文评读中纳入 15 篇，其中 13 篇为非随机研究、2 篇为随机试验；以 ROBINS-I 评估为 3 篇低、3 篇中、7 篇高偏倚风险，2 篇随机试验以 RoB-2 评为低风险。｜span: "for relevant studies published between January 2015 and March 2025"／"The search identified 196 studies, of which 55 underwent full-text review, and 15 met the inclusion criteria. Thirteen were non-randomized studies and two randomized."／"three studies showed low, three moderate, and seven high risk of bias (RoB), while both RCTs had low risk according to RoB-2"｜caveat: 检索期间为 2015 年 1 月至 2025 年 3 月；本条为证据强度标示，须与 F23 之结论并读。本站以 efetch retmode=xml 实查该篇（PMID 42434488）PublicationType 为 Journal Article／Review，未被 PubMed 索引为 Systematic Review 或 Meta-Analysis；本文转述其自述之研究设计（系统综述）时一并揭露此差异，读者宜据此降权——此降权与 F13、F16、F18 采同一标准。
  • F23｜来源#7｜confidence: low（结论措辞含 potential，且证据设计以非随机为主）｜basis: peer_reviewed｜geo: universal｜period: 2026｜claim: 清透矫治器相较传统固定矫治器，在牙齿美观与牙周健康上表现较佳，并在疗程长度与病人舒适度上具有潜在效益。｜span: "Clear aligners enhance dental aesthetics and periodontal health relative to conventional fixed appliances, offering potential benefits in treatment length and patient comfort."｜caveat: 原文为 potential benefits（潜在效益），不得改写为疗程一定较短或一定较舒适；证据基础见 F22、F24。
  • F24｜来源#7｜confidence: high（对研究设计组成此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026｜claim: 纳入的 15 篇中，有 6 篇为无对照组的长期随访，3 篇与 Twin Block 比较，1 篇与未治疗组比较，6 篇与固定矫治器比较。｜span: "Six examined long-term aligner outcomes without comparison, three compared aligners with twin block appliances, one with an untreated group, and six with fixed appliances."｜caveat: 各比较的研究篇数少，任一比较皆不宜单独解读。
  • span: "The search identified 196 studies, of which 55 underwent full-text review, and 15 met the inclusion criteria."
  • F25｜来源#8｜confidence: high（对「常见并发症」此一叙述）｜basis: peer_reviewed｜geo: universal｜period: 2026-03｜claim: 正畸引发的发炎性牙根吸收（OIIRR）是正畸治疗常见的并发症。｜span: "Orthodontically induced inflammatory root resorption (OIIRR) is a common complication of orthodontic treatment."｜caveat: 出自背景段落，未附发生率数字；本文未推估任何个人风险。
  • F26｜来源#8｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-03｜claim: 该荟萃分析纳入 4 篇高质量队列研究、共 1,204 颗前牙，清透矫治器组的牙根吸收显著少于固定矫治器组（加权平均差 -0.47 公厘，95% 置信区间 -0.55 至 -0.40；对比 -0.54 公厘，95% 置信区间 -0.75 至 -0.33）。｜span: "Four high-quality cohort studies, comprising a total of 1,204 anterior teeth, met the inclusion criteria. Root resorption was significantly lower in the CA group than in the FA group (WMD: -0.47 mm; 95% CI: -0.55 to -0.40 vs. WMD: -0.54 mm; 95% CI: -0.75 to -0.33; p < 0.01)."｜caveat: 纳入为队列研究非随机试验；测量对象为前牙，不涵盖后牙；差异于非拔牙之上颌正中门齿较为明显。读法边界（本站标示）：原文并列的 -0.47 与 -0.54 两个加权平均差是两组各自的牙根吸收量，非组间差；两者 95% 置信区间大幅重叠（-0.55 至 -0.40 与 -0.75 至 -0.33），来源未将两者差值报为效应量，该两数字本身不足以自证组间差异之统计显著性。「significantly lower」与 p < 0.01 为该来源自身之叙述，本站原样转述并标示此边界，未代为重算或背书。
  • F27｜来源#8｜confidence: high（对适用边界此一声明）｜basis: peer_reviewed｜geo: universal｜period: 2026-03｜claim: 该分析的绝对差异幅度不大，作者认为清透矫治器可能是牙根吸收风险较高者的一个有利选项；其纳入对象限 14 岁以上、前牙牙根已发育完成者。｜span: "Although the absolute difference is modest, CA may represent a favorable treatment option for patients at increased risk of OIIRR."／"Studies were eligible if they included patients older than 14 years with fully developed anterior roots"｜caveat: 适用人群限 14 岁以上牙根发育完成者，不得外推至牙根未发育完成的儿童。
  • F28｜来源#9｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2026-07-30｜claim: 迷你骨钉辅助快速颌骨扩张（MARPE）在矢状向使 SNA 增加 0.79 度、ANB 增加 1.18 度并达统计显著；垂直向指标相对稳定，未达统计显著。｜span: "MARPE led to significant increments in SNA (mean: 0.79°; 95% CI: 0.08-1.5; P = .03) and ANB (mean: 1.18°; 95% CI: 0.49-1.87; P = .0008). In contrast, the vertical dimensions remained relatively stable, with SN-MP (1.28°; P = .10) and MP-FH (1.09°; P = .44) failing to reach statistical significance."｜caveat: 对象为青少年后期与成人；统计显著不等于临床有意义，须与 F29 并读。
  • F29｜来源#9｜confidence: high（对作者自评此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2026-07-30｜claim: 该分析纳入 11 篇研究、其中 7 篇提供荟萃分析资料；作者评估这些变化的幅度相对小，对上颌后缩与下颌前突的影响在临床上是轻微的。｜span: "Eleven studies were included, seven of which provided data for the meta-analysis."／"the magnitude of these changes is relatively small, suggesting a clinically modest impact on maxillary retrusion and mandibular protrusion"｜caveat: 作者同时指出资料量有限，垂直向影响尚无定论，需高质量前瞻长期试验。本站以 efetch retmode=xml 实查该篇（PMID 42531969）PublicationType 仅为 Journal Article，未被索引为 Systematic Review 或 Meta-Analysis，且 MedlineCitation Status="Publisher"、PublicationStatus 为 aheadofprint（线上先行出版、尚未完成 MEDLINE 索引）；本文转述其自述之研究设计时一并揭露此差异，读者宜据此降权——此降权与 F13、F16、F18、F22 采同一标准。
  • F30｜来源#10｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2017｜claim: 上颌扩张后的维持期长度，在该回顾纳入的 6 篇研究中介于 4 周到 16 个月之间；维持使用固定式（压克力板、Haas、Hyrax、四角螺旋）或活动式（Hawley 与含扩张器之 Hawley）装置。｜span: "6 articles were selected and assessed for their methodological quality."／"The retention period after maxillary expansion ranged between 4 weeks and 16 months. Fixed (acrylic plate, Haas, Hyrax and quad-helix) or removable (Hawley and Hawley expander) appliances were used for retention."｜caveat: 诚实揭露一处来源内部不一致：该文英文摘要写 4 周至 16 个月，葡萄牙文摘要同段落写「4 semanas e 6 meses」（4 周至 6 个月）。本文采英文摘要之数值并标示此差异；读者若需引用，宜回查全文。对象限生长期之后牙错咬病人（原文纳入条件为 growing subjects with posterior crossbite）。推论边界（本站标示）：4 周至 16 个月为该 6 篇研究各自采用之维持方案设定范围，该回顾未论证此落差之成因，亦未主张维持长度应依个案而定；本站不由此区间推导任何临床决策原则或个人配戴指示。
  • F31｜来源#10｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2017｜claim: 该回顾作者认为，以固定式或活动式装置维持 6 个月，看来足以避免复发，或使短期随访中的变化维持在极小的程度。｜span: "Six months of retention with either fixed or removable appliances seem to be enough to avoid relapse or to guarantee minimal changes in a short-term follow-up."｜caveat: 原文措辞为 seem to be（看来），且限定于短期随访；纳入仅 6 篇研究，检索截至 2016 年 1 月；不得转述为任何个人的配戴指示。
  • F32｜来源#11｜confidence: high（对此一机制叙述）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 在成功的正畸治疗之后若没有维持期，牙齿倾向复发、回到原本的位置；维持是借由装设固定式或活动式维持器达成，以提供牙齿稳定度并避免伤害牙齿与牙龈。｜span: "Without a phase of retention after successful orthodontic treatment, teeth tend to 'relapse', that is, to return to their initial position. Retention is achieved by fitting fixed or removable retainers to provide stability to the teeth while avoiding damage to teeth and gums."｜caveat: Cochrane CD002283.pub5 之背景叙述；未指定任何个人所需的维持期长度。
  • F33｜来源#11｜confidence: high（对纳入规模与偏倚评估此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 该回顾纳入 47 篇研究、共 4377 位参与者；其中 28 篇被评为高偏倚风险、11 篇低风险、8 篇不明；多数比较与结果仅有一篇高偏倚风险研究支持，且多数研究的随访未满一年。｜span: "We included 47 studies, with 4377 participants."／"We judged 28 studies to have high risk of bias, 11 to have low risk, and eight studies as unclear."／"Most comparisons and outcomes were evaluated in only one study at high risk of bias, and most studies measured outcomes after less than a year."｜caveat: 本条为证据强度标示，须与 F34 之结论并读。
  • F34｜来源#11｜confidence: high（对「无法下明确结论」此结论）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 证据为低到极低确定性，因此无法对任何一种维持方式相对于另一种下明确结论。｜span: "The evidence is low to very low certainty, so we cannot draw firm conclusions about any one approach to retention over another."｜caveat: 作者呼吁需要随访至少两年、并测量维持器寿命、病人满意度与副作用的高质量研究。
  • F35｜来源#11｜confidence: high（对纳入条件此一事实）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 该回顾明确排除使用隐形矫治器的研究。｜span: "We excluded studies with aligners."｜caveat: 因此该回顾的维持期结论不自动适用于隐形正畸疗程结束后的情境——这是本文诚实标示的证据缺口，非该回顾的缺陷。
  • F36｜来源#11｜confidence: low（单一研究、样本小）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 在一项比较部分时间配戴活动式维持器与固定式维持器的研究中，活动式较易造成不适，但维持器失败较少、牙周健康指标较佳。｜span: "Removable retainers were more likely to cause discomfort (RR 12.22; 95% CI 1.69 to 88.52; 57 participants), but were associated with less retainer failure (RR 0.44, 95% CI 0.20 to 0.98; 57 participants) and better periodontal health (Gingival Index (GI) MD -0.34, 95% CI -0.66 to -0.02; 59 participants)."｜caveat: 为单一研究、参与者仅约 57 至 59 位，且不适之风险比置信区间极宽（1.69 至 88.52）；不得当作通则或任何装置选择的依据。
  • F37｜来源#11｜confidence: low（单一研究、样本小）｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 在一项研究中，部分时间与全时配戴 Hawley 活动式维持器，在稳定度上没有差异的证据。｜span: "There was no evidence of a difference in stability between part-time and full-time use of Hawley retainers (MD 0.20 mm, 95% CI -0.28 to 0.68; 1 study, 52 participants)."｜caveat: 单一研究、52 位参与者；「没有差异的证据」不等于「两者相同」，亦不构成任何配戴指示。
  • F38｜来源#12｜confidence: medium｜basis: peer_reviewed｜geo: universal｜period: 2023｜claim: 在固定正畸治疗的研究中，拆除装置时的白斑病灶患病率介于 12% 到 55%。｜span: "The prevalence of WSLs at debonding varied between 12 and 55%."｜caveat: 为纳入之 7 篇随机试验人群的观察范围（含涂氟与对照组），非任一人群的单一发生率，亦非个人风险预测。

FAQ

Q1. 固定矫治器和隐形矫治器，哪一种比较好？
**文献目前没有给出一面倒的答案。系统综述的结论是清透矫治器相较传统固定矫治器在牙齿美观与牙周健康上较佳，并在疗程长度与舒适度上具有潜在效益 [F23]；但该回顾纳入的 15 篇研究中有 13 篇为非随机设计、7 篇高偏倚风险，且该篇本身未被 PubMed 索引为 Systematic Review，本文据此降权 [F22]。在牙根吸收上，清透矫治器组显著较少，惟绝对差异幅度不大，且该分析纳入对象限 14 岁以上、前牙牙根已发育完成者 [F26][F27]。** 哪一种适合你，取决于分类、成因与个别条件，须由牙医师评估 [F11][F41]。
Q1. マルチブラケット装置とアライナーでは、どちらのほうが良いのですか？ — **文献は現時点で一方に偏った答えを示していません。システマティックレビューの結論は、アライナーは従来のマルチブラケット装置と比べて歯の審美性と歯周の健康において良好であり、治療期間と快適さの面で潜在的な利益をもたらす、というものです [F23]；ただし同レビューが組み入れた 15 件の研究のうち 13 件は非ランダム化デザインで、7 件は高いバイアスリスクであり、さらに同レビュー自体が PubMed で Systematic Review として索引されていないため、本記事はこれに基づいてディスカウントしています [F22]。歯根吸収については、アライナー群のほうが有意に少ないものの、絶対的な差の大きさは大きくなく、またこの分析の組み入れ対象は 14 歳以上で前歯の歯根の発育が完了している者に限られます [F26][F27]。** どちらがご自身に適しているかは分類、成因、個々の条件によって決まり、歯科医師の評価が必要です [F11][F41]。
Q1. Fixed appliances or clear aligners — which is better? — **The literature so far gives no one-sided answer. The conclusion of the systematic review is that, relative to conventional fixed appliances, clear aligners are better on dental aesthetics and periodontal health and carry a potential benefit in treatment length and comfort [F23]; but 13 of the 15 studies that review included were of non-randomised design and 7 were at high risk of bias, and the review itself is not indexed by PubMed as a Systematic Review, so this article downgrades it accordingly [F22]. On root resorption, the clear aligner group was significantly lower, though the absolute difference is modest, and the subjects included in that analysis were limited to patients older than 14 years with fully developed anterior roots [F26][F27].** Which one suits you depends on the classification, the aetiology and your individual conditions, and has to be assessed by a dentist [F11][F41].
Q2. 小孩要不要早期治疗？几岁该评估？
**依分类而定，不是依年龄一刀切。指引写的是：多数错颌畸形在早期混合齿列、晚期混合齿列与恒牙列都能被有效治疗 [F3]；但明显第 II 类可及早开始以降低前牙外伤风险、中度第 II 类宜于青春期生长高峰前或期间 [F4]，第 III 类应及早开始 [F5]，明显横向异常应及早于上颌进行 [F6]。** 儿童前牙错咬的荟萃分析也显示，早期治疗有效，但结果受病因与装置类型影响 [F11]。
Q2. 子どもに早期治療は必要ですか？何歳で評価を受けるべきですか？ — **分類によって決まるのであって、年齢で一律に線を引くものではありません。ガイドラインが書いているのは次のことです：大部分の不正咬合は混合歯列前期、混合歯列後期、永久歯列のいずれの時期でも有効に治療できます [F3]；ただし顕著な II 級は前歯部外傷のリスクを下げるために早期に開始でき、中等度の II 級は思春期の成長のピークの前または最中が望ましく [F4]、III 級は早期に開始すべきで [F5]、顕著な横方向の異常は上顎において早期に行うべきです [F6]。** 小児の前歯部反対咬合のメタアナリシスも、早期治療は有効であるが、その結果は病因と装置の種類に左右されることを示しています [F11]。
Q2. Should a child be treated early, and at what age should an assessment be made? — **It depends on the classification, not on a single cut-off by age. What the guideline writes is that most malocclusions can be effectively treated in the early mixed, the late mixed and the permanent dentition alike [F3]; but a pronounced class II anomaly can be started on early in order to reduce the risk of anterior tooth trauma, while a moderate class II one is preferably handled before or during the pubertal growth peak [F4]; a class III anomaly should be started early [F5]; and a pronounced transverse anomaly should be started on early in the upper jaw [F6].** The meta-analysis on anterior crossbite in children likewise shows that early treatment is effective, but that the outcome is influenced by aetiology and by the type of appliance [F11].
Q3. 成人还能正畸吗？骨头还会动吗？
**针对青少年后期与成人的迷你骨钉辅助快速颌骨扩张分析显示，矢状向虽有统计显著变化（SNA 增加 0.79 度、ANB 增加 1.18 度），但作者评为临床上轻微；垂直向未达统计显著 [F28][F29]。该篇为线上先行出版、尚未被 PubMed 索引为 Systematic Review 或 Meta-Analysis，本文据此降权 [F29]。** 成人个案能达成什么，需由牙医师依影像与临床条件评估 [F41]。
Q3. 大人でも矯正できますか？骨はまだ動きますか？ — **青年期後期と成人を対象としたミニスクリュー併用急速口蓋拡大の分析によれば、矢状方向には統計学的に有意な変化があったものの（SNA が 0.79 度増加、ANB が 1.18 度増加）、著者は臨床的には軽微と評価しており；垂直方向は統計学的有意に至りませんでした [F28][F29]。同論文はオンライン先行公開であり、PubMed で Systematic Review または Meta-Analysis として索引されていないため、本記事はこれに基づいてディスカウントしています [F29]。** 成人の症例が何を達成できるかは、歯科医師が画像と臨床条件に基づいて評価する必要があります [F41]。
Q3. Can adults still have orthodontic treatment — can bone still move? — **The analysis of miniscrew-assisted rapid palatal expansion in late adolescents and adults shows that, although the sagittal changes were statistically significant (SNA increased by 0.79 degrees, ANB by 1.18 degrees), the authors assess them as clinically modest; the vertical changes did not reach statistical significance [F28][F29]. That paper is an ahead-of-print online publication and is not yet indexed by PubMed as a Systematic Review or Meta-Analysis, so this article downgrades it accordingly [F29].** What an individual adult case can achieve has to be assessed by a dentist against the imaging and the clinical conditions [F41].
