矫正牙齿要找有正畸资质的医生当面检查、按时复诊，别网购牙套自己在家戴
Professional care costs more and requires follow-up visits over the treatment period.
Chinese device guidance calls for an orthodontist's supervision and regular review. The US FDA says it has not authorized clear aligners sold directly without a prescription and dental supervision.
C
Move “Use an orthodontist for an in-person exam and follow-up; do not self-treat with mail-order aligners” to Future Me's calendar
The excuse
Future Me has a clearer calendar, more patience, and apparently the same responsibilities.
What feels good now
Today I keep a little money, a few minutes, a bit of persistence and avoid interrupting my default routine.

9. 矫正牙齿要找有正畸资质的医生当面检查、按时复诊，别网购牙套自己在家戴
成本: 比网购多出挂号和复诊的钱，每隔一段时间要去一趟诊所。难在疗程常常一两年，要坚持复诊。
说人话: 透明牙套在国内是二类医疗器械，说明书要求在有正畸资质的医生指导下戴、定期复诊。美国药监部门说没批准过不经牙医开方就直接卖给个人的牙套。没人当面检查，可能咬合变歪、牙齿移错位置、疼痛，甚至掉牙。
收益: 国家药监局医疗器械技术审评中心 2022 年的《无托槽矫治器注册审查指导原则》说，这种牙套「管理类别为Ⅱ类」。它要求说明书写明「治疗过程中需在具有口腔正畸专业资质医师的指导下进行佩戴」，还要写「进食、刷牙及定期复诊的要求」。产品名称「不建议含有“隐形”等虚无、假设的概念性名称」。美国食品药品监督管理局（FDA）的说法是：「The FDA has not authorized clear aligners that are sold directly to consumers without a prescription and supervision by a dentist or orthodontist」，意思是不经牙医开方和监督、直接卖给个人的透明牙套，它一个都没批准过。FDA 还说：「In-person examination by a dentist or orthodontist can help lower the risks of uneven bite, unintended tooth movement, pain, and tooth loss」，也就是牙医当面检查能降低咬合不齐、牙齿移位、疼痛和掉牙的风险。开始戴以后定期当面复诊，才能确认牙在按计划安全移动。这两份都是监管文件，没有给出出事的比例

备注: 收益量级定为小，因为没找到出事比例，只能凭后果判断。国内药监和卫健部门针对「网购牙套在家自己戴」的风险提示没有找到，所以本条主要靠注册要求和 FDA 的说法。正畸属于医疗行为，做医疗美容性质的牙齿矫正，机构许可证要有对应科目，动手的医生要有资质，查法见本节第 2 条（机构许可证、主诊医师）。四部门 2023 年的口腔医疗通知也点名要严惩无证机构和聘用非卫生技术人员看牙。正畸医保不报，见第 24 节第 12 条（种牙之前先问清包干价）
