Abstract

The purpose of this study was to evaluate the effects of stabilization occlusal splint by using a simplified condylar path recorder and a dental sound checker. For this study, 11 subjects (10 men and 1 woman) with TMJ disorder were selected from students at Chosun University, School of Dentistry. And they were treated with the stabilization occlusal splint. The condylar movement and the TMJ sound of each subject were recorded and analyzed by using a simplified condylar path recorder and a dental sound checker. The obtained results were as follows: 1. No statistically significant reduction of reduced PRI scores occurred before and immediately after wearing of stabilization occlusal splint. 2. The reduced PRI scores after wearing of stabilization occlusal splint showed statistically significant reduction with the lapse of time. 3. After stabilization occlusal splint therapy, Fisher angle and Bennett angle had almost no change. 4. TMJ sound disappeared in 4 out of 11 subjects.
