摘　　要：目的:分析直丝弓技术治疗安氏Ⅱ类2分类患者后骨性、软组织侧貌的变化。方法:回顾性分析10例青少年安氏Ⅱ类2分类错牙合患者治疗前后的影像资料,采用头影测量软件对10例患者的头颅侧围定位片进行测量,并对测量结果进行统计分析。结果:与矫治前相比,矫治后U1-SN增大了(11.19±15.80)mm,SNA减小了(9.72±5.72)°,ANB角减小了(4.56±1.07)°,上唇凸度减小了(1.2±0.92)mm,下唇凸度增加了(0.61±2.50)mm,患者侧貌明显改善。结论:直丝弓矫治可以有效治疗安氏Ⅱ类2分类错牙合,改善患者侧貌。AIM To study the profile changes of bone and soft tissue in the addescets with class II division2 malocclusion before and after treatments with strait - archwire appliance. METHODS： Cephalometric analysis of 10 addescents with class Ⅱ division 2 was done before and after treatment with strait - archwire appliance. The data was statistically analyzed. RESULTS： After treatment U1 - SN increased by （ 11. 19 ± 15. 80） mm,SNA angle decreased by （9. 72 ±5. 72） 0 ,AJNB angle decreased by（4. 56 ± 1.07） 0,upper lip convexity decreased by （ 1.2 ± 0. 92） mm, lower lip convexity increased by （0. 61 ± 2. 50） mm. The patients ’ facial profile improved significantly. CONCLU-SION： Strait - archwire appliance is effective in the treatment of class Ⅱ division 2 malocclusion and in the improve-ment of ficial profil.
