Abstract
Previous studies showed that posterior teeth intrusion using skeletal anchorage in patients with open bite could improve overbite and retrusive chin profile by counterclockwise mandibular rotation. If the incisor intrusion is also performed, posterior teeth intrusion can be used for profile improvement of retrognathic patients without open bite, and this type of treatment can be called total arch intrusion (TAI). In retrognathic patients with lip incompetency, TAI is a very useful tool to improve the profile and lip strain. This paper shows the considerations, indications, and precautions to be taken when implementing TAI with a treated patient.
以前的研究表明，对开放性咬合患者使用骨骼固定的后牙内陷治疗可以通过下颌逆时针旋转来改善咬合过度和后突的下巴外形。如果同时进行切牙固位，后牙固位可用于改善无开放性咬合的后颏患者的外形，这种治疗方式可称为全牙弓固位（TAI）。对于唇部功能不全的后颌患者，TAI 是一种非常有用的工具，可以改善患者的外形和唇部应变。本文介绍了对接受治疗的患者实施 TAI 时的注意事项、适应症和预防措施。
