目的探讨替牙期骨性Ⅲ类错合的矫治效果。方法临床观察选取2011年1月-2012年12月之间收治的22例替牙期骨性Ⅲ类错合患者为研究对象,所有患者均接受上颌前方牵引矫治,回顾性分析患者矫治前后各项指标变化情况。结果所有患者经过矫治,各项X线指标均显著改善,且临床治疗前后各项指标对比统计学差异明显(P<0.05)。结论替牙期骨性Ⅲ类错合患者接受上颌前方牵引矫治,能够显著降低患者正颌手术的发生率,有助于生长改良,因而临床应用价值较高。
Objective To investigate the effect of orthodontic treatment on skeletal Class Ⅲ malocclusion. Methods Clinical observation Twenty-two patients with occluded stage Ⅲ malocclusion were selected from January 2011 to December 2012. All the patients underwent maxillary traction treatment. The clinical data of all patients before and after the treatment were retrospectively analyzed Indicator changes. Results All the patients underwent orthodontic treatment, and the X-ray indexes of all patients were significantly improved. There was significant statistical difference between before and after treatment (P <0.05). Conclusion Patients with skeletal class Ⅲ malocclusion during orthodontic treatment of maxillary anterior traction can significantly reduce the incidence of orthognathic surgery in patients with orthopedic surgery, which is conducive to the improvement of growth. Therefore, its clinical value is high.
