摘　　要：目的 探讨扩弓和多曲方丝弓技术在安氏Ⅲ类错(牙合)伴下颌偏斜矫治中的作用机理。方法 选择安氏Ⅲ类错(牙合)伴下颌偏斜患者8例,均采用上颌扩弓技术矫治单侧上颌后牙反(牙合),多曲方丝弓技术不同程度地直立后牙,调整后牙在三维方向的位置,并解除前牙的反(牙合),调整下颌中线。结果 8例Ⅲ类错耠伴下颌偏斜患者均取得良好的矫治效果,矫治后磨牙为中性关系,前牙覆(牙合)覆盖正常。结论 轻度及中度安氏Ⅲ类错(牙合)伴下颌偏斜畸形患者通过上颌的扩弓及多曲方丝弓矫治技术可有效地矫正磨牙关系及下颌偏斜。Objective The purpose of this study is to evaluate the methods of treatment on Class Ⅲ malocclusion with mandib-ular deviations, and clarify the principles of expansion and multiloop edgewise arch wire technique. Methods 8 skeletal class Ⅲ with mandibular deviations patients were selected (male 3,female 5, aged12-18). They were all corrected with maxillary expansion and multiloop edgewise arch wire technique. Results In all cases, molar relationships were class I, the overbite and the overjet were normal, and the upper and lower midline were harmony. Conclusion Mild and moderate skeletal class Ⅲ with mandibular deviation can be corrected successfully by maxillary expansion and multiloop edgewise arch wire technique.
