摘要
目的比较两种关闭拔牙间隙方法在正畸治疗中的临床效果。方法选择2011年2月～2011年12月在我院治疗的68例正畸治疗患者,随机分为两组,对照组患者应用标准方丝弓关闭拔牙间隙,实验组患者应用滑动直丝弓关闭拔牙间隙,比较两组患者的治疗效果、耐受度及并发症情况。结果实验组患者的中切牙伸长距离及转矩均明显短于对照组,治疗疗程及复诊时间亦明显短于对照组,患者的耐受度及并发症发生率亦明显少于对照组,两组间差异均有显著性（均P〈0.05）。结论滑动直丝弓在正畸治疗中关闭拔牙间隙治疗效果较好,可明显提高疗效,并降低并发症发生率,具有临床应用推广价值。
Objective To compare the clinical effect of two methods of extraction space closed in orthodontic treatment.Methods 68 patients of orthodontic therapy were randomly divided into two groups including the control group of patients with standard edgewise and the experimental group with a sliding closure gap straight wire.The therapeutic effect,tolerance and complications were observed.Results The incisor extrusion distance and the torque of the experimental group were significantly shorter than that of the control group（P〈0.05）.The course of treatment and follow-up time of patients in experimental group were significantly shorter than that of the control group（P〈0.05）.Tolerance and the incidence of complications of patients in experimental group were significantly less than that of the control group（P〈0.05）.Conclusion Sliding straight wire appliance in orthodontic treatment to close extraction space can significantly improve the therapeutic effect and reduce the incidence of complications.
