摘要/Abstract

摘要： 双颌前突是临床常见的牙颌面畸形,主要表现为上下唇在面部侧貌中的前突状态。根据病因学特征,该畸形可分为单纯牙性和复杂骨性两类,前者主要由切牙过度唇倾所致,后者则多伴有颌骨发育异常。对于此类患者临床上常采用代偿性治疗,即通过拔除第一前磨牙实现前牙大量内收以达到改善侧貌美观的目的。然而,现有临床研究表明,在前牙回收过程中可能伴随牙槽骨缺损和牙根吸收等医源性并发症,与多种因素密切相关,包括矫治力的大小、作用时间以及患者的个体差异等。为深入探讨这一问题,本文系统综述了正畸治疗中影响牙槽骨改建和牙根吸收的关键因素,旨在为临床实践提供科学依据和治疗指导,促进治疗方案优化和疗效提升。

Abstract: Bimaxillary protrusion, a prevalent dentofacial deformity, is characterized by excessive lip protrusion in the lateral profile. It originates from either dental causes (proclined incisors) or skeletal factors (jaw abnormalities). The standard treatment involves premolar extractions followed by anterior retraction. However, this approach carries risks of alveolar bone loss and root resorption, which vary according to force magnitude/duration and individual patient factors. This review examines the critical determinants of these complications during retraction and provides evidence-based clinical recommendations.

Key words: bimaxillary protrusion, alveolar bone remodeling, root resorption
