A comparative study of common orthodontic retainers

正畸治疗结束后仍有很多因素容易导致错畸形的复发,所以保持器的佩戴是必须的。临床上常用的保持器有:压膜保持器及其改良式、Hawley保持器和舌侧固定保持器。本文从保持效果、患者接受度及依从性、保持器对牙周组织的影响这三个方面对各个类型的保持器做一对比,期望对医师临床选择保持器有指导意义。

After orthodontic treatment,there are still many factors leading to the recurrence of the malocclusion,so wearing retainers is necessary.

This article compared the three different types of retainers from three aspects,including retention effects,patients＇ acceptability and compliance,and the influence of retainers on periodontal tissues,hoping to be helpful to orthodontists to select appropriate retainers.
