The Effectiveness of Different Therapeutic Jaw Position Determining Methods in Repositioning Splint Therapy for Temporomandibular Joint Disk Displacement Without Reduction：A Randomized Controlled Clinical Trial

The goal of this clinical trial is to learn if different therapeutic jaw position determining methods influence the efficacy of repositioning splint therapy for temporomandibular joint disk displacement without reduction. The main questions it aims to answer are: Does different therapeutic jaw position determining methods influence the efficacy of repositioning splint therapy for temporomandibular joint disk displacement without reduction? Researchers will compare the efficacy of repositioning splint therapy made with different therapeutic jaw position determining methods for temporomandibular joint disk displacement without reduction. Participants will: Take repositioning splint made with different therapeutic jaw position determining methods every day for 3-6 months. Visit the clinic once every 3 weeks for checkups and tests.
