Abstract:

Purpose. To perform complex and informative radiologic assessment of temporomandibular joints (TMJ)

Material and methods. Patients were divided into 2 groups: 1850 children and adolescents with malocclusions (Group 1), and 2150 adults with edentulous spaces or dental prostheses of different types (Group 2). Panoramic zonograhy spiral and conus computed tomography (CT), orthopantomography were performed in all the cases

Results. There were no osteal lesions of TMJ in Group 1. Intra-joint lesions of different types normalized on opening of mouth in the majority of cases, and only 22% of patients in Group 1 presented improper articular heads position. In Group 2 TMJ arthrosis was diagnosed in 29% of patients, and 25% presented uni- and bilateral restriction or uni- and bilateral subluxation.

Conclusions. The data indicates high incidence of muscles dysfunctions and TMJ lesions of muscular origin that demand orthopedic correction.
