Over the last few years, the use of self-ligating brackets in orthodontics has progressed considerably. These systems have been the subject of numerous studies with good levels of evidence making it possible to evaluate their efficacy and efficiency compared to conventional brackets. The aim of this study was to evaluate the therapeutic efficacy of self-ligating brackets by means of a systematic review of the scientific literature.
A systematic study was undertaken in the form of a recent search of the electronic Pubmed database, oriented by the use of several keywords combined by Boolean operators relating to the therapeutic efficacy of self-ligating brackets through the study of tooth alignment, space closure, expansion, treatment duration and degree of discomfort. The search was limited to randomized controlled studies, and two independent readers identified studies corresponding to the selection criteria.
The chosen articles comprised 20 randomized controlled trials. The studies analyzed revealed the absence of significant differences between the two types of system on the basis of the clinical criteria adopted, thereby refuting the hypothesis of the superiority of self-ligating brackets over conventional systems.
在过去几年中，正畸领域自锁托槽的使用有了显著进展。这些系统已成为众多研究的主题，有充分的证据水平，使得能够与传统托槽相比评估其疗效和效率。本研究的目的是通过对科学文献的系统评价来评估自锁托槽的治疗效果。
以近期检索电子PubMed数据库的形式进行了一项系统研究，通过使用布尔运算符组合的几个关键词来定向搜索，这些关键词与自锁托槽通过牙齿排齐、间隙关闭、扩弓、治疗持续时间和不适程度的研究的治疗效果相关。检索限于随机对照研究，两名独立的读者识别符合选择标准的研究。
所选文章包括20项随机对照试验。分析的研究表明，根据所采用的临床标准，两种类型的系统之间没有显著差异，从而反驳了自锁托槽优于传统系统的假设。
