Appropriate torque control of anterior teeth is of great significance to obtain ideal orthodontic treatment outcome. Clear aligners are less effective in torque control of anterior teeth due to their special application mode and material properties. Therefore, it is important to investigate how to improve the torque control of anterior teeth by using clear aligners, with the expectation of providing guidance for clinicians. This article discussed the methods to control the torque of anterior teeth by using traditional fixed appliances, the efficiency of clear aligner in controlling the torque of anterior teeth, the difficult points of clear aligner in controlling the torque of anterior teeth and the therapeutic methods to better control the torque of anterior teeth by using clear aligners.
良好的前牙转矩控制对取得理想的正畸疗效具有重要意义。无托槽隐形矫治器有特殊的施力方式及材料性能，其对前牙转矩的控制有一定局限。因此，探讨如何提高无托槽隐形矫治技术中前牙转矩控制具有重要临床意义。本文阐述传统固定矫治技术对前牙转矩控制的方法，无托槽隐形矫治器对前牙转矩控制的效率、难点以及增强前牙转矩控制的策略，以期为临床治疗提供参考。.
