A literature review was carried out on an actual, but little studied problem of dentistry — dysfunction of the temporomandibular joint with changes in the musculoskeletal system and an individual typological feature of habitual motor activity in young people. Purpose of the study. Basing on a review of modern scientific literature since 2014, it is necessary to reveal the problems of disorders of the temporomandibular joint, including psychophysiological status in young people, its relationship with changes in the musculoskeletal system and the influence of habitual motor activity on its functioning. Methodology. The data of special literature were studied using scientific search library databases: PubMed Central, Elibrary. The search for original scientific publications was carried out by keywords. This review includes an analysis of 45 scientific sources. Results and conclusions. The literature review systematizes modern scientific data on disorders in the functioning of the temporomandibular joint from a young age, the identification of preclinical and clinical manifestations in students, the influence of stress as a trigger in the development of TMJ pathology, the determination of the habitual motor activity of students and its impact on the work of the TMJ, the influence of posture on the positioning of the articular heads, as well as, with the existing pathology of the TMJ, the effect on the musculoskeletal system, as a manifestation of the defense mechanism. The review also presents current data on the study of temporomandibular joint dysfunction after orthodontic treatment. The review made it possible to identify a number of significant factors contributing to the development of TMJ dysfunction, to substantiate the practical significance of the problem, which is associated with the need for a thorough examination of the TMJ, starting from a young age. This will prevent the development of a complex of dental diseases, the development of pathologies from the musculoskeletal system, as well as the development of disorders in the work of adjacent areas of the head and neck, which will improve the quality of life of the individual and the population as a whole. Prospects for further research are formulated, which can be the basis for predicting the risk of developing TMJ pathology and the development of a complex of dental and diseases.

Subject. The study of the osseous tissue state in the dental implants setting, their functioning after the orthopedic treatment according to the climatic and geographical location. Aim of the study is to estimate the osseous tissue state in the dental implants setting, their functioning after the orthopedic treatment according to the climatic and geographical location. Methodology. The study regarding the estimation of the osseous tissue state after dental implants setting and subsequent orthopedic treatment taking them into consideration was carried out. The analysis of the medical documentation of 180 patients divided into 6 groups according to climatic and geographical location was made. The study was carried out using KBKT through definite control points to reveal the regularity of the region where the patients live, life conditions and the osseous tissue state. Results. The analysis of the received data showed that the patients living in Tyumen had the better osseous tissue state, the level of implants osseointegration and stability of the orthopedic constructions than the persons living in the north of Tyumen region. Conclusion. The level of the osseous tissue state after dental implants setting is different in the groups living in various climatic and geographical conditions including ones of the same region.

Subject. The study of the results of the examination of the patients with the temporomandibular joint dysfunction depending on the habitual physical activity type. The aim of the study is to estimate the results of the examination of the patients with the temporomandibular joint dysfunction depending on the habitual physical activity type. Methodology. 105 patients (18 male patients and 87 female patients) aged 20-35 with the occlusive temporomandibular joint dysfunction (K07.6 Diseases of temporomandibular joint) living in Tyumen and in Tyumen region were examined. The study was carried out at “the Regional stomatological polyclinic” in Tyumen. Results. The study of the peculiarities of temporomandibular joint dysfunction depending on the habitual physical activity type was carried out. The clinical results of the dynamic observation and complex functional study in 105 patients aged 20-35 having occlusive temporomandibular joint dysfunction were given. Conclusion. The results showed that there was a direct connection between the changes in dentomandibular system and the physical activity level in 105 patients aged 20-35 with occlusive temporomandibular joint dysfunction living in Tyumen and Tyumen region. In the studied subjects, with a a low level of habitual motor activi 8.43% more defects in the dentition were found in comparison with a high level of habitual motor activity, and by 6.02% more than in comparison with an average level of habitual motor activity, the pathological abrasion of the teeth was almost 2 times higher compared with a high level of habitual motor activity. An additional examination method based on computed tomography showed a violation of the articular relationship in 67.3% of cases, signs of TMJ hypermobility one and two-sided in 28.2%, changes in the position of the condyles in the joint in 33.33% of cases, in the group with a low level of habitual motor activity.
