However, even if statistically significant, such differences would be negligible in a clinical environment. Therefore, the impact of orthodontic treatment with clear aligners and fixed appliances on periodontal health status should be considered comparable.」｜caveat: 本條的重點是作者自己下的臨床意義結論（差異在臨床環境中可忽略、兩者應視為相當）；引用時不得只取「較健康」半句而略去後半句。同錨亦用於 KM-DENTAL-C03。

- 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。

• 同族 canonical 與分工（必讀）：隱形矯正要花多少錢？這筆錢是怎麼算出來的（KM-DENTAL-C03，草稿）。兩卡的 canonical 邊界：歸 C03 的是——核定收費標準表上的項次結構、官方難度分級判準、材料費另計的意義、數位流程項次、報價單怎麼逐項核對；歸本卡的是——適應症限制、療程過程的負擔、臨床風險與療程中狀況分層。重疊處（適應症範圍 F6、拔牙個案限制 F9、refinement F13、附件 F14、牙根吸收 F17、牙周 F18、維持階段 F23）本卡以本題視角重寫為「限制與風險」面向並補上新文獻（旋轉準確度 F10、成長中病人 F11、去釉 F15、病人經驗 F16、後牙開咬 F19、顳顎關節 F20、材料 F21／F22、未面診服務 F24／F25、吞入與吸入 F26／F27），費用內容未重寫，只以一句摘述指向 C03；共用的英文 span 與條文逐字一致。
• 「牙套」一詞的雙義消歧義：「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）。如果你其實在問的是假牙牙冠那一種「牙套」，先看該卡分流；本卡談的一律是矯正用的透明矯正裝置。
• 牙齦退縮的通用答案：牙齦萎縮還救得回來嗎？（KM-DENTAL-27，草稿）。本卡引用的綜述在短期追蹤中提及牙齦退縮的組間差異[F18]，但牙齦退縮本身的成因、分級與處置屬該卡的 canonical 範圍，本卡未重寫。
