摘　　要：目的采用传动直丝弓技术治疗青少年Angle Ⅱ1类错牙合,通过头影测量分析评价患者的矫治效果。方法选择40例(女24例,男16例)传动直丝弓技术矫治的Angle Ⅱ1类错牙合患者,平均年龄13.2岁。经X线头影测量分析,比较治疗前后软硬组织变化,对所得数据采用SPSS 19.0统计软件进行统计学处理。结果患者平均治疗时间12个月,治疗后均获得良好的覆牙合、覆盖及中性磨牙关系,侧貌也得到明显的改善。头影测量显示,U1-SN角、ANB角、U1-RL距、U6-RL距变小,L1-MP角、L1-RL距、L6-RL距变大,其他无显著变化。结论传动直丝弓矫治器利用口内支抗结合细丝轻力,快速倾斜移动牙齿,后期控制转矩并正轴,可快速有效矫治Angle Ⅱ1类错牙合。Objective To observe the effects of transmission straight wire technique on treating adolescents with Class Ⅱ division 1malocclusion by cephalometric analysis. Methods 40（ 24 females,16 males） subjects treated with transmission straight wire appliance were selected,whose mean age was 13. 2 years old. By analyzing the cephalograms of all subjects,soft and hard tissues before and after treatment were compared. All data were statistically analyzed by SPSS 19. 0. Results After a mean treatment time of 12 months,the molar relationship and facial profile were obviously improved. According to cephalograms,U1-SN,ANB,U1-RL,U6-RL were decreased,but L1-MP,L1-RL,L6-RL were increased. There was no significant change in other items. Conclusion The transmission straight wire appliance has a good effect on patients with class Ⅱ division 1 malocclusion,and it can also take advantage of intraoral anchorage and light-wire to move teeth quickly and obtain correct torque efficiently.
