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。
Adduction anterior teeth in Class Ⅱ malocclusion (maxillary protrusion) and bidentata patients orthodontic treatment is an indispensable step. The key to adducing the anterior teeth is to move the teeth efficiently while minimizing damage to the teeth and their supporting tissues. However, the clinical phenomenon of alveolar bone resorption, root resorption and gingival recession is common in these patients, Sometimes even affect the overall effect of orthodontic treatment. This article summarizes the adverse remodeling of tooth and periodontal tissue caused by anterior adduction and its possible causes.
