BackgroundThere are different total TMJ prostheses on the market today but no comparison of the efficacy. The purpose of this meta-analysis was to evaluate the effectiveness of different temporomandibular joint replacement (TJR) systems.MethodsA systematic review and meta-analysis was performed using the Pubmed, Embase, Medline and Cochrane Library search engines in May 2017 to identify qualified studies. The outcome measures were the changes between the pre- and postoperative maximal incisal opening (MIO), the level of pain relief, diet limitations and function deficiencies. Analyses of heterogeneity, sensitivity and publication bias were performed. A fixed-effects model was used in the meta-analysis of pooled weighted mean difference (WMD) in the MIO pre- and post-operation, pain changes, diet changes and functional improvement.ResultTwenty studies with 1262 patients were included into the meta-analysis. There was no real difference in the comparison of MIO and pain, diet, function changes pre- and post-operation of three different brands of TJR systems. The MIO and function efficiency decreased gradually with time, but the effectiveness of pain relief and improvements in diet limitation were stable with no significant differences over the follow-up period. In the comparison of the custom and stock devices, both types of prostheses performed similarly in MIO, pain, function and diet changes between pre- and post-operation.ConclusionThe analysis showed that there was no significant difference in treatment outcomes among the different brands of TJR systems.
