Abstract

Abstract: Objective: To study the CBCT imaging features of temporomandibular joint in patients with unilateral crossbite and temporomandibular joint disc displacement (DD). Methods: A total of 52 patients with unilateral crossbite and DD were enrolled in the clinical data and CBCT imagings were performed. The condyle-joint socket was reconstructed using Mimics 22.0 software, and the joint depth, joint nodule slope, joint space were measured. Data were analyzed using SPSS22.0 software. Results: The anterior space was increased in the patients with unilateral crossbite and DD. According to the position of the crossbite in the oral cavity (whether the anterior and posterior teeth were crossbite), the anterior and upper spaces in patients whose anterior and posterior teeth were non-crossbite were bigger than those had crossbite (P<0.05). Conclusion: Crossbite can cause imaging changes in the condyle-joint socket, resulting in widening of the anterior space of the affected side. CBCT can better show the changes of the skeletal structure and joint space of the temporomandibular joint.
