目的对两种牵引尖牙方法应用于口腔正畸排齐整平阶段的价值进行比较。方法选取我院2012年1月~2014年1月收治的口腔正畸患者66例作为研究对象,根据牵引尖牙方式的不同将其分为观察组与对照组,各33例。观察组采用轻弹力牵引法,对照组采用Lace-back牵引法,并对两组患者排齐后的尖牙旋转度、尖牙间宽度进行比较。结果治疗后,观察组的尖牙旋转度、尖牙间宽度均明显优于对照组,差异有统计学意义(P<0.05)。结论以轻弹力牵引法对口腔正畸患者进行排齐整平,对于患者牙列改善情况更为有利,值得临床推广。
Objective To compare the value of two kinds of traction canines applied to orthodontics. Methods Sixty-six orthodontic patients admitted from January 2012 to January 2014 in our hospital were selected as study objects. According to the different ways of traction canines, they were divided into observation group and control group, with 33 cases in each group. The observation group used light stretch traction method, the control group used Lace-back traction method, and the two groups of patients aligned canine rotation, canine width between. Results After treatment, the degree of canine rotation and canine intervertebral width in the observation group were significantly better than those in the control group (P <0.05). Conclusion The method of light stretch traction orthodontics patients alignment and leveling for the dentition patients to improve the situation is more favorable and worthy of clinical promotion.
