摘　　要：目的探讨高位头帽式肌激动器(HGAC)矫正骨性安氏II类错牙合的作用机理和疗效。方法采用HGAC对17例骨性安氏II类错牙合患者进行矫治,应用Pancherz分析法结合一些常用测量项目对治疗前后X线头影片进行对比分析。结果HGAC对上颌骨的生长发育有抑制作用,尤其体现在垂直方向上;对促进下颌骨的前后向生长、改善下颌后缩有明显作用,同时还避免了下颌顺时针旋转的负面作用;牙齿牙槽方面对上前牙有舌倾和压入效果,对下前牙的位置控制良好。结论HGAC对骨性安氏II类错牙合矫治的疗效确切,尤其适用于上牙槽发育过度以及高角型病例。Objective To evaluate the treatment effect of skeletal class II malocclusion with HGAC.Methods Seventeen skeletal Class II cases were selected and treated with HGAC,pre-treatment and post-treatment cephalometric radiographs were analyzed by Pancherz analysis. Results Maxillary growth was inhibitied by HGAC, especially in vertical direction. Mandibular retrognathism was improved significantly in horizontal direction. Meanwhile , the upper incisors were retruded and intruded. Conclutions HGAC was effective in the correction of skeletal class II malocclusion.
