CONE-BEAM COMPUTED TOMOGRAPHY AND ULTRASOUND IMAGING IN A COMPREHENSIVE ASSESSMENT OF THE ANATOMICAL AND FUNCTIONAL STATE OF THE TEMPOROMANDIBULAR JOINT
To optimize the analysis of the anatomical and functional state of the temporomandibular joint (TMJ) in patients with dento-alveolar anterior occlusive by a comprehensive evaluation of the TMJ images obtained by cone-beam computed tomography (CBCT) and ultrasound. Initially, at the time of treatment of the patient, made a clinical assessment of dentoalveolar and facial system method of a dental panoramic x-ray with subsequent cephalometric analysis lateral teleroentgenogram in the program Dolphin Imaging. Then, on the obtained image of TMJ using the CBCT method, the anatomical and functional ratio of its elements was determined by the method of automated craniometry of computer tomograms developed by us. The obtained data of TMJ CBCT were compared with the results of the ultrasound examination. The TMJ CBCT method allowed to determine the change in the position and shape of the lower jaw heads on both sides, and the ultrasound revealed the destruction of the cartilage of the articulation surface of the head, the initial signs of osteoarthritis, hypermobility of the lower jaw heads on both sides. The proposed optimization plan of examination of patients with dento-alveolar anterior occlusive can improve the quality and accessibility of comprehensive evaluation of bone and soft tissue elements of the TMJ. Based on the obtained data, recommendations for the use of this method in the planning of treatment of maxillofacial anomalies have been developed.
