Regardless of age, you should take your child to an orthodontist the moment you notice an issue.」｜caveat：美国专业学会对民众之建议，非台湾临床指引、非治疗时机的证据结论；「完成检查」不等于「开始治疗」；该页为消费者卫教页而非指引文件，本卡不以其作为疗效依据。「7 岁」为第一次检查最晚应完成之时间点，非观察等待门槛——来源同段即写明未满 7 岁察觉异常者不需等待，本卡因此在正文与 FAQ 两处都把这一句放在年龄数字之前（防止单独抽取时被读成「等到 7 岁」的等待规则）。

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：作者自陈信心为低；末句显示「儿童期治疗能否避免成年手术」在本回顾完成时仍为未决问题。

怎么找到提供这项服务的院所

本站不列出任何院所名单，也不推荐、不评比、不比较任何医疗机构。

要找提供这项服务的诊所，请用下列法定查询渠道自己查——它们的资料由主管机关维护，比任何名单都新：

>

- 台湾卫生福利部“医事机构查询”：可依县市、乡镇与科别（牙科）查出已完成开业登记的医事机构，

结果会显示机构名称、地址与登记科别。这是确认“这家有没有合法登记”的第一站。

- 台湾中央健康保险署“特约医事机构查询”：可查该院所是不是健保特约。

这关系到哪些项目走健保、哪些自费，直接影响你会拿到什么样的收费说明。

>

两个系统都在各自主管机关的官方网站上，以“医事机构查询”“特约院所查询”为关键词即可找到。

本站不转贴网址，因为网址会变动，请以主管机关当下公告的入口为准。

>

急症不要花时间查名单：影响到呼吸、吞咽、说话，或肿胀正在扩散时，直接就近挂急诊。

• 费用面的 canonical（本卡不重写）：「牙套」要多少钱？先分清楚你问的是矫正牙套还是假牙牙冠（KM-DENTAL-08，草稿）与隐形矫正要花多少钱？这笔钱是怎么算出来的（KM-DENTAL-C03，草稿）。边界：矫正费用的组成、核定收费标准表的读法、健保为何不给付的完整说明归那两张卡；本卡只在需要时一句摘述并指过去，且本卡引用同一份台北市收费标准表时取的是不同节（本卡＝口腔颚面外科节的正颚咨询公告内容＋齿颚矫正科节的中文用语；C03＝齿颚矫正科的项次结构与难度分级的费用意义）。三卡共用的健保法第 51 条第 3 款 span 逐字一致。
• 装置适应症限制的 canonical：隐形矫正有什么缺点？（KM-DENTAL-C07，草稿）。边界：透明矫正装置在各类移动上的可预测性、拔牙个案的落差、儿童骨性第二类的证据，归 C07；本卡处理的是第三类／前牙错咬这一支，两卡的人群与骨骼分类不同，不得互相套用。
