Structural features of the temporomandibular joint in patients with gnathic mesial occlusion

Abstract

The aim of the study was to evaluate the structural features of the temporomandibular joint in patients with a gnatic form of mesial occlusion of the dentition. Materials and methods. In studying the structural features of the facial skull in patients with gnatic mesial occlusion, the height of the condylar process was separately evaluated in the course of the study in order to avoid the incorrect measurement of the branch height in cases of degenerative changes in the condylar process. Results. The structural features of the temporomandibular joint were determined in 50 adult patients (aged 18–44 years old) using cone-beam computed tomography.
Сonclusion. Patients with gnathic mesial occlusion of the asymmetric group showed identical articular spaces (anterior and posterior) in the sagittal direction on both the deviating and non-deviating sides, suggesting that the bilateral relationship between the head and fossa may be as symmetrical as in patients with symmetry. However, the axial condylar angle had a bilateral difference only among patients in the asymmetric group; namely, it was significantly greater on the side of the deviating condyle.
