摘　　要：目的探讨双阻板磁力功能矫治器（ｔｗｉｎｂｌｏｃｋｍｅｇｎｅｔｉｃａｐｐｌｉａｎｃｅ，ＴＭＡ）对早期ＡｎｇｌｅⅢ类错的矫治效果。方法采用作者自己设计的ＴＭＡ对３２例生长发育期功能性骨性Ⅲ类错患者进行了矫治。通过Ｘ线头影测量、模型及面像分析，观察疗效。结果显示Ⅲ类面型获得明显改善，上下位不调得到纠正，颌面形态得到改建，疗效满意。结论磁力功能矫治方法对早期ＡｎｇｌｅⅢ类错有明显疗效。ＴＭＡ具有制作简单，结构小巧，容易测量和控制矫治力等优点。Objective The aim of this study was to evaluate the effect of magnetic functional and orthopedic approach on treatment of early skeletal class malocclusion. Methods A new type of magnetic twinblock appliance (TMA) was developed and used on 32 growing subjects with skeletal class malocclusion. Results The class dentofacial profile significantly improved and class III molar relationship was corrected in most cases. Conclusion The Nd2Fe14B TMA could be used as effective orthopedic approach in treating class malocclusion, which had many advantages, such as force prediction, wellcontrolled anchorage, small and comfortable design of appliance and good cooperation from patients.
