Abstract

Management of severe rotation poses a great challenge for the orthodontist, especially when cortical anchorage occurs. The conventional methods require excessive treatment time, rely on patient compliance, and can cause root resorption. A groundbreaking new procedure developed by Wilcko et al, which is actually a modification of the conventional corticotomy procedure, amalgamates the orthodontic mechanics, alveolar decortications, and augmentation procedure to make treatment time three to four times faster than conventional orthodontic techniques. This procedure uses the dynamics of bone physiology and redirects the emphasis in tooth movement to the manner in which supporting bone responds to orthodontic forces applied to the tooth. This article includes a case report in which the technique is used on a patient who has a severely rotated mandibular left canine.

摘要

严重扭转牙的矫治对正畸医生来说是一项巨大挑战,尤其是在出现皮质骨支抗的情况下。传统方法需要过长的治疗时间,依赖患者的配合,并且可能导致牙根吸收。Wilcko等人开发的一项开创性新程序,实际上是对传统皮质切开术的改良,它将正畸力学、牙槽骨去皮质术和植骨程序相结合,使治疗时间比传统正畸技术快三到四倍。该程序利用骨生理学的动态变化,将牙齿移动的重点重新转向支持骨对施加在牙齿上的正畸力的反应方式。本文包括一个病例报告,其中该技术应用于一名患有严重扭转的下颌左侧尖牙的患者。
