Subject. Resorption of the micellar processes of the temporomandibular joint as a result of complications during long-term orthodontic treatment. Objectives. Analysis of the patient's treatment tactics after the detection of micellar processes of the temporomandibular joint resorption. Methodology. The work was carried out at the Department of Pediatric Dentistry and Orthodontics of UGMU. The analysis of the clinical situation of the patient, whose treatment took place in an outside medical institution, was carried out. The study highlights the relevance of this problem, since resorption can lead to functional and aesthetic disorders affecting the quality of life of patients, this condition is a complex clinical problem requiring an integrated approach to diagnosis and treatment planning. The aim of the work is to analyze effective treatment tactics based on the collected data on clinical manifestations, instrumental studies and the results of conservative and surgical treatment methods. Attention is paid to diagnostic methods. The findings emphasize the importance of an individual approach to each patient and the basic principles of treatment aimed at restoring TMJ function and improving patients' lives. Accurate diagnosis and timely correction of treatment are key factors for successful therapy in cases of micellar process resorption. Conclusions. Based on the analysis of the clinical case and the literature review, the following conclusions can be drawn regarding the treatment of condylar process resorption of the temporomandibular joint (TMJ): condylar process resorption is a multifactorial disease that requires careful diagnosis to determine the etiology and degree of progression. Treatment tactics should be individualized and based on clinical manifestations, imaging data, and the general condition of the patient. Long-term monitoring of patients with condylar process resorption is necessary to assess the stability of treatment results and timely correction of emerging complications.
