目的正颌-正畸联合治疗成人骨性Ⅲ类错患者25例,并对治疗效果进行评价。方法 25例骨性Ⅲ类错成人患者,年龄为18～27岁,年龄平均21.5岁。术前患者均经正畸-正颌手术,术后行正畸手术。通过术前正畸排齐牙列,协调上下牙弓,平整曲线,建立良好的术后咬关系。术后正畸可使牙列进一步排齐,做到精细调整。摄取治疗前、后头颅定位侧位片,SPSS17.0软件包通过t检验对数据进行分析。结果术后25例患者面形均得到改善,形成良好咬关系,上、下牙弓协调。治疗前、后测量数据均有显著差异(P<0.01)。结论采用正畸-正颌联合治疗成人骨性Ⅲ类错患者,能取得美观和功能的满意效果
Objective To investigate the effect of orthognathic-orthodontic treatment on 25 cases of adult skeletal Class Ⅲ malocclusion. Methods Twenty-five patients with skeletal class Ⅲ malformations, aged 18-27 years and mean age 21.5 years old, were enrolled in this study. Preoperative patients were orthodontic - orthognathic surgery, orthodontic surgery. Preoperative orthodontic alignment dentition, coordination of the upper and lower dental arch, the formation of curves, the establishment of a good postoperative bite relationship. Orthodontics after dentition can be further aligned, so fine-tuned. Taken before and after treatment, cranial positioning flaps, SPSS17.0 software package by t test data analysis. Results After operation, the surface shape of 25 patients improved, forming a good bite relationship, coordination of upper and lower dental arch. Before and after treatment, the measured data were significantly different (P <0.01). Conclusion Orthodontic-orthognathic treatment of adult patients with skeletal Class Ⅲ malformations can achieve satisfactory results in appearance and function
