The aim of this study was to observe the effects of Tip-Edge Differential Straight-Arch Technique in treating Angle II (1) malocclusion. 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. 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). Tip-Edge appliance can effectively change the dento-alveolar position by means of the differential mechanics.
