Method of Analysis of the Temporomandibular Joint Parameters According to Magnetic Resonance Imaging

Abstract

Background. The existing variety of approaches to the treatment of temporomandibular joint (TMJ) dysfunction corresponds to the variety of methods for its diagnosing. The absence of a universal technique of updating a particular diagnostic method data makes it impossible to evaluate the effectiveness of treatment.Objective: to evaluate the universality of magnetic resonance imaging (MRI) in the diagnosis and determination of tactics for the treatment of TMJ pathologies.Material and methods. One hundred patients of different age groups and genders with and without TMJ pathology were divided into groups according to Angle’s classification: Class 1 – 27 persons, Class 2 – 41, Class 3 – 32. The studies were carried out using Green 18 computer tomograph (Vatech, South Korea), Optima MR450W magnetic resonance tomograph (General Electric, USA), Dentograph digital Roshchin axiograph (Prosystom, Russia), SAM 2PX articulator (SAM Praezisionstechnik GmbH, Germany). The RadiAnt Viewer software was used.Results. We conducted a comparative analysis of the indicators of articular structures mutual disposition obtained using various methods of TMJ diagnosis. A technique for estimating TMJ parameters using the analysis of MRI data was proposed. A correlation was revealed between the indications obtained using various diagnostic methods.Conclusion. The developed method of TMJ structures analysis has high accuracy and is applicable in practice.
