摘要： 报告1例下颌骨后缩伴上颌牙弓狭窄前突的骨性Ⅱ类错𬌗患者的双期矫治过程,该患者还伴有下颌双侧乳尖牙早失及后牙前移。一期治疗主要纠正患者的上颌牙弓狭窄、上前牙前突、下颌骨后缩及其骨性Ⅱ类错𬌗,二期治疗主要纠正患者的双侧下颌后牙前移及排齐上下颌牙列。双期治疗最终使患者达到良好的牙弓形态、牙排列、骨性面型及软组织侧貌。

Abstract: This article reviewed two-stage orthodontic treatment of a patient with skeletal ClassⅡmalocclusion with mandibular retrusion and maxillary dental arch stenosis. The patient was also accompanied by premature loss of bilateral mandibular deciduous canines and mesialization of mandibular posterior teeth. The first-stage treatment mainly corrected the maxillary dental arch stenosis, maxillary anterior teeth protrusion, mandibular retrusion and skeletal ClassⅡmalocclusion, while the second-stage treatment mainly corrected the mesialization of mandibular posterior teeth and alignment of maxillary and mandibular dentition. The two-stage orthodontic treatment finally enabled the patient to achieve good dental arch shape, tooth alignment, skeletal face pattern and soft tissue profile.

Key words: Mandibular retrusion, Maxillary dental arch stenosis, Skeletal Class Ⅱ malocclusion, Early orthodontics, Two-stage orthodontic treatment
