摘　　要：目的观察Tip Edge差动直丝弓矫治技术治疗恒牙早期安氏II类1分类错牙合的临床效果,并对其机制进行探讨。方法对9例平均年龄12.1岁的恒牙早期安氏II类1分类患者采用Tip Edge技术进行拔牙治疗,所有病例均拔除4个第一双尖牙。通过对患者治疗前后相关的头影测量项目进行统计分析,评价其治疗效果。结果9例患者平均疗程为16.1个月,治疗后其覆牙合、覆盖及磨牙关系均为正常范围,侧貌得到明显改善。相关的头影测量项目分析显示:患者治疗后的ANB、U1SN、U1L1的变化有显著差异(P<0.01);SNB、MP SN、Yaxis、U6PP、L6MP、ANS Me、N Me、S Go/N Me也有明显变化(P<0.05)。结论Tip Edge技术能够快速、高效地治疗恒牙早期安氏II类1分类错牙合。Objective To observe the clinical effects of Tip-Edge appliance in treating AngleII 1 malocclusion of early permenant dentition and discuss its mechanics.Methods Nine cases of average-aged 12.1 years old with AngleII 1 Malocclusion of Early Permenant Dentition were treated with Tip-Edge appliance. All those cases were extracted 4 premolars. The results of cephalometric measurements of pretreatment and posttreatment were statistically analysed to evaluate orthodontic effects. Results The average treatment time was 16.1 months. Overbite , overjet and molar relationship were turned to normal and lateral appearances were improved after treatment. The results of cephalometric analysis show that the changes of ANB、U1-SN and U1-L1 were statistically significant(P<0.01) and the changes of SNB、MP-SN、Yaxis、U6-PP、L6-MP、ANS-Me、N-Me、S-Go/ N-Me were notable(P<0.05).Conclusion Tip-Edge appliance can effectively and quickly treat AngleII1 malocclusion of early permenant dentition.
