Clear aligner treatment (CAT) has been cited as a safe and comfortable orthodontic procedure for adult patients. However, the available evidence is scarce.
To perform a systematic review of the existing literature in order to assess periodontal health during CAT.
Pubmed, Pubmed Central, National Library of Medicine's Medline, Embase, Cochrane Central Register of Controlled Clinical trials, Web of Knowledge, Scopus, Google Scholar, and LILACS were searched from January 1945 to September 2014 to identify all peer-reviewed papers potentially relevant to the review.
After duplicate selection and extraction procedures, the risk of bias was assessed according to the Centre for Reviews and Dissemination criteria, and a 3-point grading system, as described by the Swedish Council on Technology Assessment in Health Care (SBU), was used to rate the methodological quality of the selected papers. A PICOS table was used for data extraction.
Five relevant articles were selected from the 1247 identified articles. The level of evidence was moderate for all the studies. A significant improvement of the periodontal health indexes was revealed, in particular when CAT was compared to fixed appliances. No periodontal CAT adverse effects were observed in the selected studies.
Periodontal health indexes were significantly improved during CAT. The results of this review should be interpreted with some caution because of the number, quality, and heterogeneity of the included studies.
对于成年患者而言，透明矫治器治疗（CAT）被认为是一种安全且舒适的正畸治疗方法。然而，现有证据并不充分。
对现有文献进行系统综述，以评估透明矫治器治疗期间的牙周健康状况。
检索了1945年1月至2014年9月期间的PubMed、PubMed Central、美国国立医学图书馆的Medline、Embase、Cochrane临床对照试验中心注册库、Web of Knowledge、Scopus、谷歌学术以及拉丁美洲和加勒比卫生科学数据库（LILACS），以识别所有可能与该综述相关的同行评审论文。
经过重复筛选和提取程序后，根据综述与传播中心的标准评估偏倚风险，并采用瑞典卫生保健技术评估委员会（SBU）描述的3分制评分系统对所选论文的方法学质量进行评分。使用PICOS表格进行数据提取。
从1247篇已识别的文章中筛选出5篇相关文章。所有研究的证据水平均为中等。牙周健康指数有显著改善，尤其是与固定矫治器相比时。在所选研究中未观察到透明矫治器治疗的牙周不良反应。
在透明矫治器治疗期间，牙周健康指数有显著改善。由于纳入研究的数量、质量和异质性，本综述的结果应谨慎解读。
