摘要
目的探讨正畸联合正颌治疗对骨性Ⅲ类错颌畸形伴偏颌患者侧貌改善及咬合功能的影响。方法选择接受正畸联合正颌治疗患者27例。比较正颌手术前后患者软组织的不对称率,评价患者外貌改善情况;同时比较正颌手术前后患者正中咬紧时不同肌束的表面募集电位和肌不对称指数,评价患者咬合功能。结果正颌手术后3个月患者两侧上唇偏斜量和两侧下唇偏斜量的Q值较治疗前1个月降低,而两侧下颌偏斜量的Q值较治疗前1个月升高(P<0.05);治疗后3个月右侧咬肌募集电位、左右两侧的二腹肌募集电位低于治疗前1个月,治疗后6个月的左右颞肌募集电位、左右咬肌募集电位和左右二腹肌募集电位明显高于治疗前1个月和治疗后3个月,差异有统计学意义(P<0.05);治疗后3个月患者的颞肌不对称指数、咬肌不对称指数和二腹肌不对称指数较治疗前1个月明显升高,治疗后6个月颞肌不对称指数、咬肌不对称指数和二腹肌不对称指数均较治疗前1个月和治疗后3个月明显降低,差异有统计学意义(P<0.05)。结论对骨性Ⅲ类错颌畸形伴偏颌患者采用正畸联合正颌治疗,疗效显著且稳定,可以同时满足患者对美容和咬合功能恢复的要求,值得临床推广。
Objective To investigate the effect of combined orthodontic and orthognathic treatment on profile improved and occlusal function of the patients with skeletal Ⅲ malocclusion and mandibular shifting.Methods The clinical data of 27 patients were analyzed.All patients received orthodontic treatment combined with orthodontic treatment.We compare the rate of soft tissue asymmetry before and after surgery to evaluate the improvement of the appearance of the patients.We compare muscle surface raise potential and muscle asymmetry index before and after surgery to evaluate occlusal function.Results The Q value of the upper and lower lip deviation 3 months after orthognathic surgery was lower than that of one month before treatment, while the Q value of the bilateral mandibular deviation was higher than that of one month before treatment（P〈0.05）.Three months after treatment, the right masseter muscle recruitment potential, the left and right sides of the abdominal muscle recruitment potential were lower than those of one month before treatment.After 6 months of treatment, the recruitment potential of the left and right temporal muscles, the right and left masseter muscle recruitment potential and the right and left sides of the abdominal muscle of the two groups were significantly higher than those of one month before treatment and three monthes after treatment（P〈0.05）.Three months after treatment, the asymmetry index of the temporal muscle, the asymmetry index of the masseter muscle and the asymmetry index of the two abdominal muscles were significantly increased, but those were decreased at six monthes after treatment when compared with a month before the treatment and three monthes after the treatment（P〈0.05）.Conclusion The orthodontic treatment combined with orthognathic treatment is very effective.The curative effect is remarkable and stable, and it can meet the requirements of the patients to restore the beauty and the occlusal function.It is worthy of clinical promotion.
