Abstract：
This article reviews and critically analyzes the literature on mini-implants (temporary anchorage devices) for anterior en masse retraction in orthodontics. The search methods used were an E-database search, a secondary computerized search of orthodontics journals, and a reference list of selected studies. Eligibility criteria included individuals who underwent orthodontic treatment for correction of malocclusion with premolar extraction. Data were taken from PubMed and Scopus as well as the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews. Keywords used for searching the article were temporary anchorage devices, premolar extraction, orthodontics, and anterior en masse retraction, Anterior en masse retraction with sliding mechanics in pre-adjusted edgewise appliances was considered for the study. Data collection and analysis involved three different researchers performing three steps of selection. All titles were initially filtered for irrelevant review articles. In the first step, all summaries from the selected studies were reviewed, and in the second, the entire content of the papers was read. The study was then discarded based on qualifying standards. A chart was created using the data from the final chosen research as well as the findings. The following information was evaluated for the final table: author, publication year, research structure, study group, sample size, methods/measures, study findings, and conclusion about frictionless mechanics. Results showed that a meta-analysis was not feasible due to clinical and statistical variability, as well as variations in study design, sample selection, and sample size. Thus, it was concluded that sliding mechanisms are widely employed in orthodontic treatment, but temporary anchorage devices and sliding mechanisms deliver great results. There is a need to raise awareness about these devices and use them with care.
摘要：
本文回顾并严格分析了有关正畸中用于前部整体回缩的微型植入物（临时锚固装置）的文献。使用的搜索方法是电子数据库搜索，对正畸学期刊的二次计算机搜索，和选定研究的参考列表。合格标准包括接受正畸治疗以矫正前磨牙拔除错牙合的个体。数据来自PubMed和Scopus以及Cochrane对照试验中央登记册和Cochrane系统评价数据库。用于搜索文章的关键词是临时锚固装置，前磨牙提取,正畸学,和前部整体缩回，该研究考虑了在预先调整的边缘矫正器中使用滑动力学进行整体收缩。数据收集和分析涉及三个不同的研究人员进行三个选择步骤。所有标题最初都被过滤为不相关的评论文章。第一步,对选定研究的所有摘要进行了审查，在第二个，阅读了论文的全部内容。然后根据合格标准丢弃该研究。使用来自最终选择的研究的数据以及发现创建图表。对最终表格评估了以下信息：作者，出版年份,研究结构，研究组,样本量,方法/措施，研究结果,关于无摩擦力学的结论。结果表明，由于临床和统计学差异，荟萃分析不可行，以及研究设计的变化，样本选择，和样本量。因此，结论是滑动机制在正畸治疗中被广泛使用，但是临时锚固装置和滑动机构提供了很好的效果。有必要提高对这些设备的认识并小心使用它们。
