【摘要】：目的:应用同行评估等级(peer assessment rating,PAR)指数评价Tip-edge plus差动直丝弓矫治器和Smart Clip自锁托槽矫治器的治疗效果。方法:选取南京医科大学附属口腔医院正畸科2007~2013年采用Tip-edge plus差动直丝弓技术和Smart Clip自锁托槽矫治技术完成治疗的患者,以治疗前相同的PAR总分值将患者进行配对,分为Tip-edge plus差动直丝弓矫治组和Smart Clip自锁托槽矫治组,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,对两组患者的测量数据进行统计学检验。结果:治疗后Tip-edge plus差动直丝弓矫治组前牙排列的PAR分值高于Smart Clip自锁托槽矫治组(P0.01),前牙排列效果较Smart Clip自锁托槽矫治组略差,而治疗后覆牙合的PAR分值Tip-edge plus差动直丝弓矫治组低于Smart Clip自锁托槽矫治组(P0.01),控制覆牙合效果较Smart Clip自锁托槽矫治组略好。2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(P0.05)。结论:2种矫治技术各有所长,均能取得较好的治疗效果。
[Abstract]:Objective: to evaluate the efficacy of Tip-edge plus differential wire appliance and Smart Clip self-locking bracket appliance by peer evaluation grade assessment rating index. Methods: the patients of orthodontic department of Department of Orthodontics, affiliated Stomatology Hospital of Nanjing Medical University, who were treated with Tip-edge plus differential wire arch technique and Smart Clip self-locking bracket correction technique from 2007 to 2013, were matched according to the same PAR total score before treatment. The patients were divided into Tip-edge plus differential straight wire appliance group and Smart Clip self-locking bracket correction group. The model was measured with PAR index before and after treatment. The PAR scores and their differences were recorded before and after treatment. The measured data of the two groups were statistically tested. Results: after treatment, the PAR score of anterior teeth in Tip-edge plus differential straight wire appliance group was higher than that in Smart Clip self-locking bracket group (P 0.01), and the effect of anterior tooth arrangement was a little worse than that in Smart Clip self-locking bracket correction group. However, the PAR score of overbite after treatment in Tip-edge plus differential straight wire appliance group was lower than that in Smart Clip self-locking bracket correction group (P0.01). The effect of overbite control was slightly better than that of Smart Clip self-locking bracket correction group. 2. 2 group had better PAR scores after treatment and before treatment. There was no significant difference in PAR difference between the two groups (P 0.05). Conclusion the two kinds of correction techniques have their own strong points and can achieve better therapeutic effect.
