摘　　要：目的:探讨骨皮质切开术辅助治疗轻度骨性Ⅱ类错牙合正畸的效果。方法:对7名骨皮质切开术辅助治疗的轻度骨性Ⅱ类1分类错牙合成人患者矫治前后的CBCT进行三维测量分析。结果:骨皮质切开的患者前牙内收时间为3.2个月;上中切牙明显内收,上颌牙槽骨也有内收,随着上颌切牙的内收上唇内收明显。结论:骨皮质切开术辅助矫治骨性Ⅱ类错牙合成人患者能够加速牙齿移动,并尽可能地实现前牙的整体内收,改善了患者软组织侧貌。Objective： To investigate the effects of corticotomy assisted orthodontic treatment for mild skeletal Class Ⅱ malocclusion.Methods： 7 adult patients with mild skeletal Class Ⅱ division 1 malocclusion were included and underwent corticotomy assisted orthodontic treatments. 3D measurements and analysis of CBCT data before and after treatment were conducted. Results： The average duration of upper anterior teeth retraction was 3. 2 months. After treatment,obvious retraction of up incisiors with the retraction of maxillary alveolar bone and the upper lip backward and downward movement were observed. Conclusion： Corticotomy assisted orthodontic treatment is effective in the treatment of mild skeletal Class Ⅱ malocclusion by the retraction of uper anterior teeth,alveolarar bone and softtissue profile improvement.
