摘要/Abstract

摘要： 根尖外吸收是正畸治疗后常见的并发症,其发生率为0%～100%。其由多种因素引起,大致可分为生物学因素和机械因素。生物学因素包括遗传易感性、系统性疾病、性别、药物摄入等,机械因素包括正畸力的大小、类型、持续时间,牙移动的量和类型,牙的超限移动。本文对前牙内收移动与根尖外吸收的关系及其评价方法做一综述。

Abstract: External apical root resorption was a common phenomenon associated with orthodontic treatment. The reported incidence ranged from 0% to 100%. It was caused by several factors, which could be mainly divided into biological and mechanical aspects. Biological factors included genetic susceptibility, systemic diseases, gender and medication intake. Mechanical factors consisted of the magnitude of orthodontic force, force type and duration, types of tooth movement, as well as excessive tooth movement. This review discussed the relationship between the movement type during retracting the anterior teeth and the external apical root resorption and its evaluation methods.

Key words: Retraction of anterior teeth, External apical root resorption, Torque
