Abstract:

Objective The aim of this studywas to observe the effects ofTip-Edge Differential Straight-ArchTechnique in treat- ing AngleⅡ1malocclusion.Methods 13 adults with AngleⅡ1malocclusion 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 differen- tial mechanics.
