摘　　要：目的　观察Tip_Edge差动直丝弓矫治技术治疗成人安氏Ⅱ类 1分类错的效果。方法　对 13例平均年龄为 2 4 3岁的成年安氏Ⅱ类 1分类患者采用Tip_Edge技术进行治疗。通过对患者治疗前后的头影测量主要数据的统计学分析 ,评价其治疗效果 ,并探讨Tip_Edge差动直丝弓技术治疗安氏Ⅱ类 1分类错的机制。结果　 13例患者经平均疗程为 16 2个月的治疗后 ,均获良好的覆、覆盖及中性磨牙关系 ,侧面形也得到明显的改善。X线头影测量显示 ,患者治疗后的上下中切牙切缘距AP线的距离分别缩短 3 72mm、1 0 3mm ,覆盖减少 3 73mm ,与治疗前比较有显著差异 (P <0 0 1) ;除下中切牙明显压低外 ,下磨牙还出现了一定量的伸长 (P <0 0 5 )。结论　Tip_Edge技术可通过差动机制作用于成人安氏Ⅱ类 1分类错患者的牙及牙槽骨 ,使之在维护牙周健康的同时快速而有效地达到治疗效果。Objective\ The aim of this study was to observe the effects of Tip_Edge Differential Straight_Arch Technique in treating AngleⅡ\+1 malocclusion. Methods\ 13 adults with Angle Ⅱ\+1 malocclusion were treated with Tip_Edge appliance. The results of cephalometric measurements before and after treatment were statistically analyzed. Results\ The average treatment time was 16 2 months. The results of cephalometric measurement showed that UIC_AP decreased by 3 72 mm (P<0 01), LIC_AP decreased by 1 03 mm (P<0 01), LIC_MP decreased by 1 59 mm(P<0 01), L6_MP increased by 0 99 mm (P<0 05), the over jet decreased by 3 73 mm (P<0 01).Conclusion\ Tip_Edge appliance can effectively change the dento_alveolar position by means of the differential mechanics.\;
