Sander Ⅲ矫治器和Frankel Ⅲ矫治器的临床对比研究

Sander Ⅲ and Frankel Ⅲ correctional implement clinical efficacy comparative study

目的:比较SanderⅢ矫治器和FrankelⅢ矫治器矫治AngleⅢ类反牙合畸形的矫治疗效。方法:从西安交通大学口腔医院2013年-2015年正畸科门诊随机抽取24例AngleⅢ类反牙合患者,分两组:实验组:12例配戴SanderⅢ矫治器10个月;对照组:12例配戴FrankleⅢ矫治器12个月,将治疗前后患者的头颅定位侧位片用Steiner和Tweed分析法测量,再用Spss18.0统计软件进行配对t检验。结果:两组分别配戴SanderⅢ矫治器和FrankelⅢ矫治器,临床结果显示AngleⅢ牙性、功能性和轻度骨性患者的反牙合畸形纠正,两组比较统计数据有非常显著统计学意义(P<0.01)的有:SNA(°)、ANB(°)、UI-LI(°)、面突角(°)。结论:实验组和对照组均对矫治AngleⅢ类牙性、功能性和轻度骨性患者有矫治效果,实验组和对照组比较下颌相对颅底、面突角和上颌前牙前倾改变明显,面型改变明显,矫治轻度骨性效果良好。

Objective Compare the efficacy of Sander III and Frankel Ⅲ correctional implement correct Class III malocclusion.Methods From xi ＇an jiaotong university stomatological hospital in 2013-2015,random drawing 24 cases of class III dental patients in orthodontic department outpatient,The patients are divided into two groups：experimental group consists of 12 people wearing Sander Ⅲ correctional implement 10 months,control group includes 12 people wearing Frankel Ⅲ correctional implement 12 months.Compare the Pretreatment and posttreatment cephalometric measurement results using Steiner and Tweed analysis method,reoccupy Spss18.0 statistical software matching t test.Results In two groups,one wearing Sander Ⅲ and the other wearing Frankel Ⅲ correctional implement,clinical results show that two groups of Class III malocclusion（teeth,functional and synostosis Class III malocclusion） have been corrected,to compare the statistics,we found a significant statistical significance（P〈0.01） with SNA（°）,ANB（°）,UI-LI（°）,Surface coign（°）.Conclusion Both of the experimental group and the control group in the efficacy of correcting Class Ⅲ malocclusion are highly effective;Comparing two grops find that SL distance,face Angle and maxillary anterior teeth forward change obviously,surface type change obviously,and the effect of correcting synostosis Class III malocclusion is good.
