Short-term effectiveness of a prefabricated occlusal appliance in patients with myofascial pain.

Aims: To compare the short-term effectiveness of a stabilization appliance with a prefabricated occlusal appliance in myofascial pain patients in a randomized controlled trial.

Methods: Sixty-five patients at 2 centers were assigned to a stabilization appliance group (S group, n = 33) or a prefabricated appliance (Relax) group (R group, n = 32). The patients had been suffering from temporomandibular disorder (TMD) pain for 3 months to 40 years.
