title: Effects of occlusal splint therapy on TMJ dysfunction.
abstract: A study was conducted to ascertain what happens to dysfunction symptoms followed only by occlusal splint therapy. Four hundred eighty-six pantograms were made on 15 experimental patients over a period of 5 months to 1 year. Five control patients were monitored over this same period but received no occlusal therapy. The experimental patients with TMJ dysfunction were treated with occlusal splint therapy. The occlusal splints were worn until the dysfunction symptoms were reduced and the pantographic PRI scores were reproducible. The occlusal splints were than removed without occlusal adjustments and the patients were monitored pantographically. A statistical analysis was performed on the PRI scores to determine the relationship between experimental and control patients. Experimental patients had an average drop of 21.7 points during occlusal splint therapy as compared to 3.8 points for control patients. All experimental patients had an increase in the PRI score levels following the removal of the occlusal splints.
