目的：观察掩饰性正畸治疗成人高角骨性Ⅱ类错牙合畸形的临床疗效。方法：采用直丝弓矫治技术，对15例成人高角骨性Ⅱ类患者进行代偿性治疗，并对其治疗前后头颅定位侧位片进行测量分析。结果：治疗前后U1／SN减小（11．80±10．72）°，L1／MP减小（9．33±6．47）°，（P＜0．01）；L6／MP增加（4．67±7．40）°，（P＜0．05）；SN／MP减小（1．80±3．14）°，OP／SN减小（4．20±4．20）°，（P＜0．05）；U1－PP增加（1．07±4．18）mm，（P＞0．05）；L1－MP增加（0．27±5．60）mm，（P＞0．05）；U6－PP增加（0．33±4．51）mm（P＞0．05）；L6－MP增加（0．67±1．27）mm，（P＞0．05）。结论：高角骨性Ⅱ类错牙合畸形通过掩饰性治疗后，牙合平面、下颌平面逆时针旋转，上下颌切牙明显内收，磨牙及切牙垂直高度得到较好控制。

Objective:The aim of this study was to evaluate the treatment effects of camouflaged orthodontic tech-nique in the treatment of skeletal Class Ⅱ high-angle malocclusions in adult. Method:15 skeletal classⅡhigh-angle pa-tients were chosen based on the criteria included into this study and treated by straight wire appliance technology. The cephalometric X-ray films were measured. Result:Cephalometric analysis showed that U1/SN decreased by (11.80 ± 10.72)° and L1/MP decreased by (9.33±6.47)°(P<0.01). L6/MP increased by (4.67±7.40)°(P<0.05)、SN/MP de-creased by(1.80±3.14)°、OP/SN decreased by(4.20±4.20)°(P <0.01)、U1-PP increased by(1.07±4.18)mm(P >0.05)、L1-MP increased by(0.27±5.60)mm(P >0.05)、U6-PP increased by(0.33±4.51)mm(P >0.05) and L6-MP increased by (0.67 ±1.27)mm (P >0.05). Conclusion:After treatment of camouflaged orthodontic technique in the treatment of skeletal ClassⅡhigh-angle malocclusions in adult、occlusal plane rotated anti-clockward,upper and lower anterior tooth was retract-ed obviously and the vertical height of molar and incisor showed no significant changes.
