摘要：

内收前牙在安氏Ⅱ类错牙合畸形（上颌前突）及双颌前突患者正畸治疗中是不可或缺的步骤。内收前牙的关键在于能够高效移动牙齿的同时将对牙齿及其支持组织的损害减小至最低限度，然而临床上牙槽骨吸收、牙根吸收及牙龈退缩等现象在上述患者中很常见，有时甚至影响到正畸治疗的整体效果。本文对正畸内收前牙所导致牙体及牙周组织的不利改建及可能原因进行综述。

Abstract:

Abstract：In cases of bimaxillary protrusion and Angle Class Ⅱ malocclusion（maxilla hyperplasia），extraction of premolars and orthodontic treatment with retraction of the anterior teeth is a widely used approach. Minimizing the damage to teeth and their supporting tissue when moving teeth efficiently is needed. However many findings have shown that alveolar bone loss，root resorption and gingival recession occur after retracting the anterior teeth. Sometimes it even affects the overall effect of orthodontic treatment. This paper made a review of the adverse reconstruction of teeth and periodontal tissue caused by anterior teeth retraction and its possible risk factors.
