This study investigated the effect of stabilization splints on masticatory muscle pain and sleep bruxism. Sixteen patients with masticatory muscle pain and sleep bruxism participated in this study. Electromyographic activities of the masseter muscle during sleep were recorded at baseline, immediately after, and 1, 4, and 6 weeks after insertion of the stabilization splint. Muscle palpation pain and Oral Health Impact Profile 49 scores tended to improve in the stabilization splint group compared with controls. The number of sleep bruxism events tended to decreased immediately after wearing the stabilization splint, but gradually returned to baseline.
