摘要: 目的: 探讨微种植体支抗下安氏Ⅱ1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Ⅱ1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Ⅱ1类高角患者后,后牙合平面倾斜度减小,下颌骨逆时针旋转。

Abstract: Objective: To evaluate the posterior occlusion plane change of the adults with Angle classⅡ division 1 hyperdivergent malocclusion treated by mini-implant anchorage. Methods: 44 patients (aged 18-35 years) with Angle class Ⅱ division 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 classⅡ division 1 hyperdivergent malocclusion treated by mini-implant anchorage decreases, and the mandible rotates counterclockwise.
