Regardless of age, you should take your child to an orthodontist the moment you notice an issue.」｜caveat：美國專業學會對民眾之建議，非台灣臨床指引、非治療時機的證據結論；「完成檢查」不等於「開始治療」；該頁為消費者衛教頁而非指引文件，本卡不以其作為療效依據。「7 歲」為第一次檢查最晚應完成之時間點，非觀察等待門檻——來源同段即寫明未滿 7 歲察覺異常者不需等待，本卡因此在正文與 FAQ 兩處都把這一句放在年齡數字之前（防止單獨抽取時被讀成「等到 7 歲」的等待規則）。

We have low confidence in these findings and more studies are required to reach reliable conclusions.」另 span:「should last long enough to evaluate whether orthodontic treatment in childhood avoids the need for jaw surgery in adulthood」｜caveat：作者自陳信心為低；末句顯示「兒童期治療能否避免成年手術」在本回顧完成時仍為未決問題。

• F39｜混合齒列期 2×4 固定矯正裝置不良反應的證據量。｜來源 #16｜confidence=moderate｜basis=peer_reviewed（系統性回顧）｜period=2025-01 發表｜geo: universal｜PMID 40439212｜span:「82 patients with mean-age of 10-year, mostly with pseudo class-III malocclusion, anterior cross-bite and crowding treated using 2 x 4 appliance were found.」另 span:「The literature-based evidence related to the adverse effects of 2 × 4 orthodontic appliances was found to be inadequate in quantity, but majority was of high quality (low risk of bias).」｜caveat：「證據量不足」不等於「沒有風險」；該摘要未列出具體不良反應項目，故本卡不列舉任何項目；納入研究數少、樣本 82 人。
• F40｜咬合不正與兒童青少年疼痛型顳顎關節障礙的關聯與證據等級。｜來源 #17｜confidence=moderate｜basis=peer_reviewed（系統性回顧）｜period=2025-04-03 發表｜geo: universal｜PMID 40248012｜span:「Most of the studies showed that malocclusion may be associated with TMD-pain signs/symptoms in children and adolescents. The most frequent relationship was found between the prevalence of pain-related TMD and posterior crossbite, Class II malocclusion, Class III malocclusion, and anterior open bite.」另 span:「The certainty of evidence was assessed as low, according to the GRADE approach.」另 span:「However, given the limited reliability of existing research and the inconsistencies observed across studies, additional well-structured, long-term investigations are necessary.」｜caveat：關聯不等於因果；GRADE 證據確定性為低；本卡因此不寫任何「地包天會造成顳顎關節障礙」之句子。

• F44｜正畸合併正顎治療前中後的口腔健康相關生活品質。｜來源 #26｜confidence=moderate｜basis=peer_reviewed（系統性回顧與統合分析）｜period=2022-03 發表，檢索至 2020-02-03｜geo: universal｜PMID 35194682｜span:「Two studies (87 participants) were included in a meta-analysis showing improvement of OHRQoL when comparing before and after treatment were compared (mean 14.85 scale points, 95% confidence interval 10.36;19.35).」另 span:「Studies indicate a decrease in OHRQoL during the pre-surgical orthodontic treatment phase but improvement after orthodontic-orthognathic treatment. Data substantiating these results are limited, and the quality of evidence is low.」另 span:「All six studies had a serious risk of bias.」另 span:「Patients should be well informed about the effect facial/esthetic changes may have on their OHRQoL during sequential phases of orthodontic-orthognathic treatment.」｜caveat：量表點數的方向依所使用之問卷（OHIP-14／OQLQ-22）而定，本卡照原文措辭記為改善，未自行換算或解釋方向；納入的 6 篇研究全部具嚴重偏誤風險、僅 2 篇 87 人進入統合、證據品質為低；為族群層級估計，不得推定任何個人的療程體驗。

However, there was lack of evidence on long-term benefits.」｜caveat：本卡不採用本篇的任何統合數值，僅記錄其結論方向與 Cochrane 2024 一致（長期效益證據不足）。理由有二：①其檢索僅至 2016-06，已被檢索至 2023-01 的 Cochrane 更新版在時效上覆蓋；②本篇「面罩 vs 未治療」的 reverse overjet 合成值與 Cochrane 2024 所報「3 年追蹤」的 overjet 值數字完全相同（同為 2.5 mm、95% CI 1.21 至 3.79），其成因未經本站查證（可能源自同一批原始試驗資料），為避免讀者或 AI 把兩者當成互相佐證的獨立數據，本卡一律只採 Cochrane 2024 之數值。

怎麼找到提供這項服務的院所

本站不列出任何院所名單，也不推薦、不評比、不比較任何醫療機構。

要找提供這項服務的診所，請用下列法定查詢管道自己查——它們的資料由主管機關維護，比任何名單都新：

>

- 衛生福利部「醫事機構查詢」：可依縣市、鄉鎮與科別（牙科）查出已完成開業登記的醫事機構，

結果會顯示機構名稱、地址與登記科別。這是確認「這家有沒有合法登記」的第一站。

- 中央健康保險署「特約醫事機構查詢」：可查該院所是不是健保特約。

關係到哪些項目走健保、哪些自費，直接影響你會拿到什麼樣的收費說明。

>

兩個系統都在各自主管機關的官方網站上，以「醫事機構查詢」「特約院所查詢」為關鍵字即可找到。

本站不轉貼網址，因為網址會變動，請以主管機關當下公告的入口為準。

>

急症不要花時間查名單：影響到呼吸、吞嚥、說話，或腫脹正在擴散時，直接就近掛急診。

• 費用面的 canonical（本卡不重寫）：「牙套」要多少錢？先分清楚你問的是矯正牙套還是假牙牙冠（KM-DENTAL-08，草稿）與隱形矯正要花多少錢？這筆錢是怎麼算出來的（KM-DENTAL-C03，草稿）。邊界：矯正費用的組成、核定收費標準表的讀法、健保為何不給付的完整說明歸那兩張卡；本卡只在需要時一句摘述並指過去，且本卡引用同一份臺北市收費標準表時取的是不同節（本卡＝口腔顎面外科節的正顎諮詢公告內容＋齒顎矯正科節的中文用語；C03＝齒顎矯正科的項次結構與難度分級的費用意義）。三卡共用的健保法第 51 條第 3 款 span 逐字一致。
• 裝置適應症限制的 canonical：隱形矯正有什麼缺點？（KM-DENTAL-C07，草稿）。邊界：透明矯正裝置在各類移動上的可預測性、拔牙個案的落差、兒童骨性第二類的證據，歸 C07；本卡處理的是第三類／前牙錯咬這一支，兩卡的族群與骨骼分類不同，不得互相套用。
