Occlusal splint therapy in the treatment of myofascial pain dysfunction syndrome, and associated muscles

ABSTRACT

Three different full coverage types of occlusal devices were used in the present study to evaluate their effects on patients with myofacial dysfunction syndrome [MPD]. It was found that the hard acrylic device had more significant therapeutic effect for relieving pain of TMJ and masticatory muscles compared with soft resilience and combination [hard and soft] devices. On the other hand, no one of these devices had a significant effect on the elimination of TMJ clicking at the end of final evaluation period
