A Class III malocclusion associated with dental asymmetry is a complex diagnostic and treatment problem in orthodontics. The goals of maintaining or improving the facial profile and achieving good function are decisive factors when considering whether to plan a surgical or a nonsurgical treatment approach. A fixed appliance in combination with extractions could be considered for nonsurgical management of this type of malocclusion in the permanent dentition. This article presents the results of an orthodontic approach to a Class III subdivision malocclusion in an adult treated with mandibular first molar extractions. The extractions provided the space needed to correct the overjet and overbite and to improve the intercuspation.
安氏 III 类错颌伴有牙列不对称是正畸中一个复杂的诊断和治疗问题。在考虑是否计划手术或非手术治疗方法时，维持或改善面型和实现良好功能的目标是决定性因素。对于恒牙列中这种类型的错颌，固定矫治器结合拔牙可被认为是非手术治疗的选择。本文介绍了一例成人安氏 III 类亚类错颌的正畸治疗方法，该患者采用下颌第一磨牙拔牙获得所需间隙以纠正前牙覆盖和覆颌，并改善尖牙交错关系。
