Abstract

OBJECTIVE

The aim of this study was to observe the effects of Tip-Edge Differential Straight-Arch Technique in treating Angle II (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.

摘要

目的

本研究旨在观察Tip-Edge差动直丝弓技术治疗安氏II类1分类错牙合的效果。

方法

对13例安氏II类1分类错牙合成人患者采用Tip-Edge矫治器进行治疗。对治疗前后的头影测量结果进行统计学分析。

结果

平均治疗时间为16.2个月。头影测量结果显示，上前牙切缘至翼上颌裂距离（UIC-AP）减小3.72 mm（P<0.01），下前牙切缘至翼上颌裂距离（LIC-AP）减小1.03 mm（P<0.01），下前牙切缘至下颌平面距离（LIC-MP）减小1.59 mm（P<0.01），下颌第一恒磨牙至下颌平面距离（L6-MP）增加0.99 mm（P<0.05），覆盖减小3.73 mm（P<0.01）。
