| 摘 要： | 【目的】探讨上颌后牙牙合垫联合前方牵引治疗替牙期骨性Ⅲ类错牙合高角病例的效果及矫治机理。【方法】对9例患者采用上颌后牙牙合垫式矫治器联合前方牵引进行治疗，并作治疗前后X线头影测量分析。【结果】上颌骨及上前牙前移，前牙覆盖增加4.18mm（P<0.001）；前面高、前下面高及后面高增加，上下颌骨无明显旋转，面部软组织侧貌有一定改善。【结论】上颌后牙牙合垫联合前方牵引能有效矫正替牙期骨性Ⅲ类错牙合高角病例的矢状关系，对垂直向无明显不利影响，但不能改变患者的垂直骨面型。

| Abstract: | 【Objective】To evaluate the treatment effect of maxillary protraction on skeletal class Ⅲ high angle cases in mixed dentition.【Methods】Nine patients were treated with combined posterior occlusal acrylic and maxillary protraction.The cephalometric radiographs were analyzed before and after the treatment.【Results】The maxilla and maxillary dentitions moved forward.Overjet increased by 4.18mm (P<0.001).The anterior and posterior total face height increased.The maxilla and mandible showed no significant rotation.Profiles were improved to some extent.【Conclusion】A combined posterior occlusal acrylic and maxillary protraction can correct the sagittal maxillo-madibular interrelationships,with no unfavourable influence on facial vertical dimension.But the treatment does not change the vertical skeletal pattern. |
