Обзор

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.

Процедура Repositioning splint therapy with jaw position determined by mechanical articulator
The therapeutic jaw position will be determined by the following steps: 1. Pre-treatment Jaw Position Recording Participants were seated upright with relaxed posture, eyes facing forward, and the Frankfort plane parallel to the floor. Intercuspal position (ICP) was recorded using silicone registration material. Edge-to-edge position of central incisors was recorded for protrusive position. Left/right lateral positions were recorded with opposing canines aligned. 2. Transfer of Jaw Positions Fol
Процедура Repositioning splint therapy with jaw position determined by ai-assisted virtual articulator
The jaw position was determined by the following steps: 1. AI-Based Segmentation and Reconstruction of Jaw Models CBCT DICOM data was imported into an ai-based craniomaxillofacial bone segmentation system to reconstruct 3D models of the jaws and dentition. The mandibular/maxillary bone models and dental arches were exported as .ply files. These .ply files were then imported into Exocad software. 2. Virtual Transfer of Jaw Positions Bilateral AI-segmented medial pole points of the condyles and t
Процедура Repositioning splint therapy with jaw position determined by ai-assisted virtual patient
The jaw position was determined by the following steps: 1. AI-Based Segmentation and Reconstruction of Virtual Patients: CBCT DICOM data was imported into an ai-based craniomaxillofacial bone segmentation system to reconstruct 3D models of the jaws and dentition. The trajectory of mandibular movement was recorded by an electronic facebow. 2. Virtual Transfer of Jaw Positions Bilateral AI-segmented medial pole points of the condyles and the right infraorbital point were annotated in cross-se
