摘要:
提要:骨性Ⅱ类错牙合畸形的掩饰性治疗是正畸矫治的难点之一。正畸掩饰性治疗通过不同的拔牙模式,移动上下牙齿,来掩饰上下颌骨间的Ⅱ类不调关系,改善软组织侧貌。其常见的拔牙模式包括:双颌拔除[4 4] 、[4 4] 或[4 4] 、[5 5] ,单颌拔除[4 4] ,或再补充拔除 [1]或 [1]。应根据颌骨畸形程度和生长型、磨牙远中关系程度、牙列拥挤度等畸形特征,具体分析,严格选择。矫治过程中,应结合不同拔牙方案的矫治特点,注意支抗、前牙转矩等的控制,以获得相对理想的治疗效果。

Abstract:
Summary:The camouflage treatment for skeletal Class Ⅱ malocclusion is one of the challenges in orthodontics. To compensate the skeletal Class Ⅱ discrepancy and improve the soft tissue profile,different extraction model is adopted to provide space for repositioning the teeth. The common extraction models are as follows:bimaxillary extraction of four first premolars or upper first and lower second premolars,single maxillary extraction of upper first premolars or one lower incisor added,which should be selected strictly according to a concrete analysis of clinical characteristics such as the severity of skeletal deformity,growth pattern,molar relationship and dental crowding. To achieve the desired effect,we should consider the therapeutic characteristic of different extraction models and pay a lot of attention to the control of anchorage,incisor torque, etc. during the orthodontic treatment.
