he problem of choosing a method of examination in the pathology of the temporomandibular joint (TMJ) is one of the most difficult issues in modern radiology and maxillofacial surgery. In particular, the question of radiology methods usage in the study of the TMJ state after orthodontic treatment remains unexplored. When examining patients with suspected TMJ pathology, a wide range of methods are used: from ultrasound to high-tech methods -computed and magnetic resonance imaging, however, the lack of a single examination algorithm and the ambiguity in the choice of treatment for patients after orthodontic treatment indicates the high relevance of this problem.A review of the literature on radiology of the TMJ after orthodontic treatment is presented, the advantages and limitations of various methods are identified, indicating the features of the research technique. Information on functional methods of TMJ research is also presented.
