Abstract: Objective: To analyse the efficacy of the stabilization splint in the treatment of anterior disk displacement without reduction. Methods: Thirty-six patients (29 females, 7 males) of anterior disk displacement without reduction were treated with stabilization splint.The period of treatment was 3 months. Visual analog pain scale (VAS) and mouth opening were recorded before and immediately after the insertion of splint. T-test for matched pairs was used to assess the effectiveness of the splint. Results: After 3-month-treatment, VAS reduced from 5.66±1.28 to 1.46±1.14 and mouth opening increased from 26.93±2.64mm to 38.35±2.04mm. Analysis showed a statistically significant difference of P<0.001. However, postinsertion MRI showed no recapture of disks. Conclusion: The stabilization splint is effective in treating anterior disk displacement without reduction ,despite its effect is helping bilaminar zone of temporomandibular joint remodeled to function as a disc, not recapture of disks.
