双阻板磁力矫治器矫治早期AngleⅢ类错He

目的 探讨双阻板磁力功能矫治器对早期ＡｎｇｌｅⅢ类错Ｈｅ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Ｈｅ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Ｈｅ位不调得到纠正,颌面形态得到改建,疗效满意。和功能矫治方法对早期ＡｎｇｌｅⅢ类错Ｈｅ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。

The effects of twin-block magnetic appliance on the early skeletal Class III malocclusion]

OBJECTIVE: The aim of this study was to evaluate the effect of magnetic functional and orthopedic approach on treatment of early skeletal class III malocclusion. METHODS: A new type of magnetic twin-block appliance (TMA) was developed and used on 32 growing subjects with skeletal class III malocclusion. RESULTS: The class III dentofacial profile significantly improved and class III molar relationship was corrected in most cases. CONCLUSION: The Nd2-Fe14-B TMA could be used as effective orthopedic approach in treating class III malocclusion, which had many advantages, such as force prediction, well-controlled anchorage, small and comfortable design of appliance and good cooperation from patients.
