稳定咬合板治疗慢性颞下颌关节盘不可复性移位的临床随机对照试验的系统评价

ObjectiveThis study aims to assess the efficacy of stabilization splint(SS) treatment on patients with chronic temporomandibular joint disk displacement without reduction(DDwoR) through systematic review of relevant randomized controlled trials.MethodsAn electronic search strategy was performed on Cochrane Central, Medline, EMBASE(Ovid), Chinese Biomedical Database, and China National Knowledge Infrastructure until July 2015. A manual search covering 19 dental journals in Chinese was performed as well. Data extraction of included studies and risk of bias assessment with the recommended tool of Cochrane Collaboration was then performed. Meta-analysis was processed by Rveman 5.3.5.ResultsFour studies of unclear risk of bias and two studies of high-risk bias were included. Compared with other conservative therapies, SS did not show a significant advantage(P>0.05) on pain relief and maximal mouth opening of DDwoR patients in the short term. However, SS may have increased the success rate(P<0 .01) in the long term.ConclusionHigh-quality randomized controlled trials are necessary for the evaluation of the long-term efficacy of SS treatment on chronic DDwoR.
