正畸正颌联合治疗骨性牙颌畸形25例临床观察

Clinical observation of orthodontic and orthognathic methods in treatment of 25 patients with skeletal malocclusion

摘要: 目的:探讨骨性牙颌畸形的治疗方法,为临床治疗提供参考。方法:25例骨性牙颌畸形患者经正畸科、正颌外科等相关医师共同制定出治疗方案,先行去除牙代偿,调整牙颌曲线等术前正畸,再通过正颌手术纠正上、下颌骨不调,最后再由正畸科医师对患者牙列进行调整和保持。结果:25例患者的面形均有明显改善,获得了良好的咬合关系。患者术前、术后SNB角、ANB角头影测量差异均有统计学意义(P0.05和P0.01)。结论:正畸正颌联合方法是治疗成人骨性牙颌畸形一种较好的临床方法。

Abstract: Objective:To explore the treatment method for skeletal malocclusion and provide references for clinic.Methods:Twenty-five patients with skeletal malocclusion were treated with orthodontic and orthognathic means.The first step,the therapeutic schedules were formulated.The compensation of teeth was removed for adjusting dentural defect curve,then orthognathic surgery was performed for all cases.Finally the dentitions were adjusted by orthodontic treatment for 2 months.Results:The facial contour of 25 cases were significantly improved,and occludingrelation was good.The angles of SNB and ANB were greatly changed,and there was significant difference before and after the treatment(P0.05 and P0.01).Conclusions:Combination of orthodontic and orthognathic treatment is a good clinical method for skeletal malocclusion.
