摘　　要：目的:研究成人严重骨性Ⅲ类错畸形在正颌外科治疗的术前与术后正畸的特点及难点。方法:成人严重骨性Ⅲ类错病例35例,对该类畸形的临床特点、正颌手术前后正畸治疗方法和注意事项进行分析研究。结果:术前正畸治疗必须完成个别牙齿错位的调整,纠正牙弓形态与宽度的不调和牙齿代偿的去除;术后正畸的主要目的是牙弓内残留间隙的关闭和咬合关系的进一步精细调整。结论:只有完善的术前、术后正畸治疗与正颌外科手术相互配合,才能较好地完成成人严重骨性Ⅲ类错的临床治疗。Objective： To discuss the characteristics and difficulties of orthodontic treatment of skeletal class Ⅲ malocclusion before and after orthognathic surgery .Method： 35 patrents with skeletal class Ⅲ malocclusion which treated by combined orthodontic-orthonganthic surgery treatments were reviewed to find out the specialties of this kind of therapy.
