摘要/Abstract

摘要： 目的:系统评价自锁托槽与传统托槽在非拔牙矫治中牙弓宽度的变化。方法:检索Cochrane Library、ScienceDirect、PubMed、CBM、CNKI、维普全文数据库、万方数据库及Google文献检索,查找自锁托槽与传统托槽对非拔牙矫治牙弓形态影响的临床研究,检索时限从建库截至2013年5月。由2名研究者独立评价纳入研究的质量并提取资料,采用Sata10.0软件对纳入的研究进行meta分析。结果:纳入8项研究,共364例患者。Meta分析结果显示,自锁组与传统组相比,矫治前、后在上颌第一前磨牙区[WMD=0.724,95%CI(0.288,1.160);PU﹤0.01]、下颌第一磨牙区[WMD=0.564,95%CI(0.219,0.909);PL﹤0.01]宽度增加量和上前牙倾斜度增加量有显著差异。结论:现有的临床证据表明,在轻中度拥挤非拔牙矫治中,自锁托槽对上颌第一前磨牙和下颌第一磨牙区的扩弓效果优于传统托槽,且能更好地控制上前牙的倾斜度,但仍需更多高质量的临床研究予以验证。

Abstract: PURPOSE: To evaluate the influence of self-ligating and conventional brackets on dental arch width in non-extraction treatment. METHODS: Cochrane library, ScienceDirect, PubMed, CBM, CNKI, VIP, Wanfang Database and Google scholar were searched from the date of their establishment to May.2013,to find clinical trials about dental arch form changes in non-extraction treatment with self-ligating and conventional brackets. The quality of the included studies was assessed by two reviewers independently, and Meta analysis was performed using Sata10.0 software package. RESULTS: Finally’ 8 studies including 364 patients were identified. The results of meta analysis showed there were significant difference between self-ligating and conventional brackets in the upper first premolar width change [WMD=0.724,95%CI(0.288,1.160);PU﹤0.01], lower first molar width change [WMD=0.564,95%CI(0.219,0.909);PL﹤0.01] and upper incisors inclination changes. CONCLUSIONS: Current clinical evidence suggests that there is more increment of the dental width in upper first premolars and the lower first molars using self-ligating brackets than conventional brackets, and self-ligating brackets can superiorly control upper incisor inclination. The results need to be verified via larger and higher quality trial.
