To evaluate the torque expression of self ligating (SL) orthodontic brackets and conventionally ligated brackets and the torque expression in active and passive SL brackets.
Our systematic search included MEDLINE, EMBASE, CINAHL, PsychINFO, Scopus, and key journals and review articles; the date of the last search was April 4th 2016. We graded the methodological quality of the studies by means of the Quality Assessment Tool for Quantitative Studies, developed for the Effective Public Health Practice Project (EPHPP).
In total, 87 studies were identified for screening, and 9 studies were eligible. The quality assessment rated one of the study as being of strong quality, 7 (77.78%) of these studies as being of moderate quality. Three out of 7 studies which compared SL and conventionally ligated brackets showed, conventionally ligated brackets with highest torque expression compared to SL brackets. Badawi showed active SL brackets with highest torque expression compared to passive SL brackets. Major and Brauchli showed no significant differences in torque expression of active and passive SL brackets.
Conventionally ligated brackets presented with highest torque expression compared to SL brackets. Minor difference was recorded in a torque expression of active and passive SL brackets. Systematic review, self ligation, torque expression, conventional ligation.
评估自结扎正畸托槽和传统结扎托槽的转矩表达以及主动和被动自结扎托槽的转矩表达。
我们的系统检索包括MEDLINE、EMBASE、CINAHL、PsychINFO、Scopus以及主要期刊和综述文章；最后一次检索日期为2016年4月4日。我们通过为有效公共卫生实践项目（EPHPP）开发的定量研究质量评估工具对研究的方法学质量进行分级。
总共识别出87项研究用于筛选，9项研究符合条件。质量评估将其中1项研究评为高质量，7项（77.78%）研究评为中等质量。在比较自结扎托槽和传统结扎托槽的7项研究中，有3项研究表明，与自结扎托槽相比，传统结扎托槽的转矩表达最高。巴达维表明，与被动自结扎托槽相比，主动自结扎托槽的转矩表达最高。梅杰和布劳赫利表明，主动和被动自结扎托槽的转矩表达没有显著差异。
与自结扎托槽相比，传统结扎托槽的转矩表达最高。主动和被动自结扎托槽的转矩表达存在微小差异。系统评价、自结扎、转矩表达、传统结扎。
