To evaluate the incidence of orthodontic brackets detachment during orthodontic treatment.
Using electronic databases; eligible studies up to January 2018 were retrieved, independently reviewed, and screened. The Coleman Methodology Scoring System (CMS) and Cochrane Collaboration's tool were used to assess quality and risk of bias in the included studies.
Of the seventeen studies included in the final synthesis, thirteen were categorized as randomized clinical trials (RCTs), one prospective cohort and retrospective survey each, whereas two studies could not be categorized. The number of patients in the selected studies ranged between 19 and 153; the mean age was between 10.5 to 38.7 years, and male to female ratio was 353:495. Almost all studies had a high risk of bias, and more than half of the studies had CMS score of 70 or above. The numbers of brackets examined in the studies ranged between 361 and 3336. The incidence of brackets detachment ranged from 0.6 to 28.3%.
The incidence of brackets detachment during orthodontic treatment is high.
评估正畸治疗期间正畸托槽脱落的发生率。
利用电子数据库；检索截至2018年1月符合条件的研究，进行独立评审和筛选。采用科尔曼方法评分系统（CMS）和Cochrane协作网的工具来评估纳入研究的质量和偏倚风险。
在最终纳入的17项研究中，13项被归类为随机临床试验（RCT），1项为前瞻性队列研究，1项为回顾性调查，而2项研究无法归类。所选研究中的患者人数在19至153之间；平均年龄在10.5至38.7岁之间，男女比例为353:495。几乎所有研究都有较高的偏倚风险，超过一半的研究CMS评分为70或以上。研究中检查的托槽数量在361至3336之间。托槽脱落的发生率在0.6%至28.3%之间。
正畸治疗期间托槽脱落的发生率较高。
