应用PAR指数评价不同矫治技术的治疗效果

PAR index in evaluation of the treatment outcome of different techniques

目的应用PAR指数评价Damon、SmartClip自锁托槽矫治技术以及MBT滑动直丝弓矫治技术的临床应用效果。方法选取北京大学深圳医院口腔科2006~2009年采用Damon自锁托槽矫治技术、SmartClip自锁托槽矫治技术以及MBT矫治技术不拔牙矫治完成治疗的错畸形患者,以治疗前相同的PAR总分值将患者进行配对分为3组,每组30例,对治疗前后模型进行PAR指数测量,记录治疗前后PAR分值及其差值以及每组疗程,对两组患者的测量数据进行统计学检验。结果治疗后Damon组前牙排列的PAR分值略高于另外两组,前牙排列效果较其他两组略差。3组患者治疗后其余各项PAR分值及治疗前后PAR差值差异均无统计学意义(P<0.05)。Damon组平均疗程与MBT组比较缩短2.36月,而SmartClip组疗程比MBT组长2.65月。结论3种矫治技术均能取得较好的治疗效果,而疗程略有差异。

Objective To evaluate the effects of the Damon technique,Smart Clip technique and MBT technique in non-extraction samples using the peer assessment rating(PAR) index.Methods 90 cases were selected to assess pre-treatment and post-treatment dental casts.Based on the same pre-treatment PAR score,samples were divided into three groups,each had 30 cases.The data were statistically analyzed.Results The post-treatment PAR score of the anterior tooth alignment in the Damon group was a little bit higher than in the...
