Abstract

A network meta-analysis (NMA) of randomized controlled trials (RCTs) was performed to assess the effectiveness of various types of occlusal splint in the management of temporomandibular disorders (TMDs) and to rank them according to their effectiveness. An electronic search was undertaken to identify RCTs published until August 2019. Predictor variables were control, non-occluding splint, hard stabilization splint (HSS), soft stabilization splint (SSS), prefabricated splint, mini-anterior splint, anterior repositioning splint (ARS), and counselling therapy (CT) with or without HSS. Outcome variables were pain improvement, post-treatment pain intensity, improvement in mouth opening, and disappearance of temporomandibular joint (TMJ) sounds. Forty-eight RCTs were included. There was a significant decrease in post-treatment pain intensity in arthrogenous TMDs after ARS (low quality evidence), CT+HSS (moderate quality evidence), mini-anterior splints (very low quality evidence), and HSS alone (low quality evidence), when compared to the control. There was a significant decrease in post-treatment pain intensity in myogenous TMDs with mini-anterior splints (very low quality evidence), SSS (very low quality evidence), CT alone (moderate quality evidence), CT+HSS (moderate quality evidence), and HSS alone (moderate quality evidence), when compared to control. ARS and CT were superior in decreasing TMJ clicking than control and HSS alone. The three highest-ranked treatments for post-treatment pain reduction in arthrogenous TMDs were ARS (92%, very low quality evidence), CT+HSS (67.3%, low quality evidence), and HSS alone (52.9%, moderate quality evidence). For myogenous TMDs, they were mini-anterior splints (86.8%, low quality evidence), CT+HSS (61.2%, very low quality evidence), and HSS alone (59.7%, moderate quality evidence). Based on this NMA of 48 RCTs, there is moderate to very low quality evidence confirming the effectiveness of occlusal splint therapy in the treatment of TMDs. Multimodal therapy consisting of CT+HSS may produce the maximum improvement for TMD patients.
