摘要
目的:探讨微种植体支抗下安氏Ⅱ^1类高角患者拔牙矫治后[牙合]平面的变化。方法:选取44例拔除上颌第一前磨牙和下颌第二前磨牙矫治的安氏Ⅱ^1类高角患者,年龄18~35岁;微种植体组(A组)和单纯拔牙治疗组(B组)各22例,测量并分析治疗前后的头颅侧位片。结果:A组矫治后OP-diff增大,SNA、ANB、SN-MP、FH-AOP、FH-POP、U1-PP减小(P<0.05)。B组矫治后SN-MP、FH-AOP、FH-POP、OP-diff、U1-PP、U6-PP、L6-MP增大,SNA、SNB、L1-MP减小(P<0.05)。其余差异无统计学意义(P>0.05)。结论:微种植体支抗矫治成人安氏Ⅱ^1类高角患者后,后[牙合]平面倾斜度减小,下颌骨逆时针旋转。
Objective:To evaluate the posterior occlusion plane change of the adults with Angle classⅡdivision 1 hyperdivergent malocclusion treated by mini-implant anchorage.Methods:44 patients(aged 18-35 years)with Angle classⅡdivision 1 hyperdivergent malocclusion who had extracted the upper 1st premolars and lower 2st premolars were treated with mini-implant anchorage(Group A,n=22)and non-anchorage(Group B,n=22),respectively.Pre-treatment and post-treatment cephalograms were measured and analyzed.Results:After treatment,in group A:OP-diff increased(P<0.05),while SNA,ANB,SN-MP,FH-AOP,FH-POP,and U1-PP decreased(P<0.05).In group B:SN-MP,FH-AOP,FH-POP,OP-diff,U1-PP,U6-PP,and L6-MP increased(P<0.05),while SNA,SNB,and L1-MP decreased(P<0.05).The changes of other indexes were not statistically different(P>0.05).Conclusion:The posterior occlusion plane angle in the adults with Angle classⅡdivision 1 hyperdivergent malocclusion treated by mini-implant anchorage decreases,and the mandible rotates counterclockwise.
