摘要/Abstract

摘要： 目的采用传动直丝弓技术治疗青少年AngleII1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AngleII1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AngleII1类错牙合。

Abstract: Objective To observe the effects of transmission straight wire technique on treating adolescents with Class Ⅱ division 1 malocclusion 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.

Key words: transmission straight wire appliance, Angle class Ⅱ division 1 malocclusion, cephalometric
