中文摘要：

自锁托槽系统是近年来正畸医师关注的焦点之一。和传统托槽系统相比,自锁托槽的摩擦力低,能提供持续性轻力,对转矩控制良好。此外,还具有减轻疼痛,缩短椅旁时间,减少就诊次数,利于牙周健康等特点。与此同时,自锁托槽也存在着不利于改正牙齿扭转,没有明显的扩弓优势等问题。本文从临床出发,结合作者的经验,阐述自锁托槽系统的优势与局限性,展望其未来发展趋势,以期为正畸医师的临床应用提供参考。

英文摘要：

In recent years, self-ligating brackets have been one of the concerns of orthodontists. Compared with conventional brackets, self-ligating brackets have lower frictional resistance and can provide persistent low force. Meanwhile, they help with better torque control, pain alleviation, chair time reduction, fewer visits and better periodontal health. However, self-ligating brackets have a problem that they are not in favor of correcting rotation and they have no obvious in terms of arch expansion. Based on clinical application and the authors＇ experience, this article presents the advantages, limitations and development trend of self-ligating brackets, in order to provide reference for its clinical application.
