摘要/Abstract

摘要： 随着无托槽隐形矫治技术的创新与发展,其在复杂拔牙病例中的临床应用日益增多。然而,受隐形矫治器材料特性以及治疗方案设计等因素的影响,在内收前牙关闭间隙过程中容易出现“过山车效应”(roller-coaster effect,RCE)。因此在使用无托槽隐形矫治器时,如何减少过山车效应的发生是临床医生关注的重点和难点。本文将对无托槽隐形矫治技术在前磨牙拔除病例中产生“过山车效应”的生物力学机制及其临床应用进展进行综述。

Abstract: With the innovation and development of clear aligner therapy, its application in treating complex extraction cases was increased in clinical settings. However, due to the material properties of clear aligners and issues in treatment plan design, the "roller-coaster effect" often occurs during the retraction of anterior teeth and space closure. Thus, reducing the roller-coaster effect when using clear aligners has become a key focus and challenge for clinicians. This paper explores the biomechanical mechanisms of the roller-coaster effect in clear aligner therapy for premolar extraction cases and reviews the progress in its application.
