目的:总结外科-正畸联合矫治下颌前突Ⅲ类错的疗效观察。方法:2004～2008年按照术前正畸→正颌手术→术后正畸序列,治疗下颌前突Ⅲ类错80例。全组病例中男性44例、女性36例,年龄27～43岁。全部选用了以SSRO为主体的手术方案。结果:80例患者均取得较为满意的面形改善和咬关系重建效果。全组病例中坚持完成矫治程序的占97.3%(75/80)。而由于患者居住地址远离城市和其它原因未能完成术后正畸的占6.3%(5/80)。前者关系稳定性优于后者,防止了复发。结论:从医患两方面仍需加强对外科-正畸联合矫治的认识,坚持做到每一例患者完成术前术后正畸,对提高正颌手术效果具有重要意义。
Objective: To summarize the curative effect of surgical - orthodontic treatment of class Ⅲ malocclusion of mandibular protrusion. Methods: From 2004 to 2008, 80 cases of type Ⅲ malocclusion of mandibular prognathism were treated according to orthodontic surgery, orthognathic surgery and orthodontic sequence.
