Abstract

We reported, that a combination of intraoral administration of NSAIDs and mouth opening exercise would be the most appropriate primary treatment for TMJ closed lock without OA. The aim of this study was to evaluate a secondary treatment in patients with TMJ closed lock without OA who had no effect from primary treatment. The subjects were 24 patients who were refractory to primary treatment. We performed arthrocentesis, with a single injection of a steroid and NSAIDs, and mouth opening exercise in the patients. This therapy was continued for a maximum of 12 weeks, until TMJ symptoms improved. Eighty-three percent of the patients showed improvement. The results suggested that this method would be a preferable secondary treatment for disk displacement without reduction with no osseous change, when primary treatment had no effect.
