In the past 10 years, self-ligating brackets have captured the interest of many clinicians and enjoyed increasing popularity. These brackets have been developed to overcome the disadvantages of stainless steel or elastomeric ligatures in terms of ergonomics, efficiency, deformation, discoloration, plaque accumulation, and friction. A self-ligating bracket does not require any type of ligature because it is has a mechanical device that opens and closes the edgewise slot. Secure archwire engagement may be accomplished by a built-in clip. Depending on the interaction between the bracket and archwire, self-ligating brackets can be active and passive. The aim of this article is to describe a new active self-ligating bracket system designed to noticeably reduce the amount of friction that normally originates from archwire-slot interaction, particularly during the correction of horizontal and vertical discrepancies.
在过去10年里，自锁托槽吸引了众多临床医生的关注，并越来越受欢迎。开发这些托槽是为了克服不锈钢或弹性结扎丝在人体工程学、效率、变形、变色、菌斑积聚和摩擦力方面的缺点。自锁托槽不需要任何类型的结扎丝，因为它有一个打开和关闭槽沟的机械装置。可以通过内置夹子实现弓丝的牢固就位。根据托槽与弓丝之间的相互作用，自锁托槽可分为主动型和被动型。本文的目的是描述一种新型主动自锁托槽系统，该系统旨在显著减少通常源于弓丝-槽沟相互作用的摩擦力，尤其是在矫正水平和垂直差异期间。
