【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㩳0.01]、下颌第一磨牙区[WMD=0.564,95%CI(0.219,0.909);PL㩳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]:Objective: to evaluate the changes of arch width between self-locking brackets and traditional brackets in non-extraction orthodontics. Methods: to search the Cochrane Library Science Direct PubMedCBI, Weip full-text database, Wanfang database and Google literature search, to find out the clinical study of the effects of self-locking brackets and traditional brackets on the shape of non-extraction dental arch. The retrieval time was from the construction of the database to May 2013. The quality of the study was evaluated by two researchers and the data were extracted. Meta analysis was carried out with Sata10.0 software. Results: a total of 364 patients. Meta-analysis results showed that there were significant differences between the self-locking group and the traditional group before and after treatment in the maxillary first premolar region [WMD-0.72495CI0.288CI0.2881.160], and the mandibular first molar area [WMD0.56495CI0.2190.909PLP0.01]. Conclusion: the available clinical evidence shows that in the treatment of mild and moderate crowding and non-extraction, the effect of self-locking brackets on the expansion of maxillary first premolar and mandibular first molar region is superior to that of traditional brackets, and the inclination of anterior teeth can be better controlled. But more high-quality clinical studies are needed.
