Relevance. Treatment of the temporo-mandibular joint (TMJ) dysfunctions still stays an urgent issue of modern stomatology. Its significance is predisposed for its high incidence and annual increase in patients’ referrals as well as diversity of it clinical manifestations, complexity of diagnosis and treatment, variability of clinical pattern, which requires a multi-disciplinary approach. According to Ukrainian and foreign authors, the TMJ pathologies take up the third place after caries and parodontal diseases, being diagnosed in 20 % of children and almost 87 % of adults. The share of patients with the TMJ dysfunction increases every year. The 79 % are represented with the intra-capsular disorders of the temporo-mandibular joints. The study was necessitated by the fact that there is still no single agreement in the treatment methods and definite treatment protocols regarding the intracapsular TMJ disorders. Objectives: analysis of efficiency of the TMJ intracapsular disorders patients’ treatment using the pathogenetically rationalized conservative and mini-invasive surgical methods. Methods and materials. The study includes the data of 38 patients with complaints of the TMJ region pain and the TMJ dysfunction. All patients were examined according to the common protocol. According to the disorder stage, the patients were administered either the conservative treatment course using the treatment tray on the mandible or maxilla, with the subsequent orthopedic or prosthetic treatment, or the splint therapy with subsequent surgical intervention. Results. Having analyzed the dynamical pattern of the treatment outcomes within the study, it has been detected that the surgical injection correction of the TMJ disorders was effective in all examined patients. To provide for the long-term steady treatment outcome the prosthetic-orthopedic rehabilitation measures were indicated, aimed at preserving the correct occlusion relation. Conclusion. The method of hyaluronic acid preparations injection into the TMJ cavity as a stage of the TMJ dysfunction therapy has proven its effectiveness in all the examined patients. In order to achieve the long-term steady result, the patients were recommended prosthetic-orthopedic rehabilitation for producing and supporting the occlusion relation.

Annotation. The pathology of the temporomandibular joint (TMJ) is one of the most difficult in the practice of the dentist, so patients go to different doctors. Often, the disease is psychosomatic, so patients have a history of stress, sleep disorders, headaches, chronic fatigue. The aim of the study is to study and comparatively analyze the nature and extent of psychological manifestations in patients with dysfunction of the temporomandibular joint according to the degree of clinical manifestations of the pathology irritability. In total, we examined 834 people with CNS dysfunction who had different etiologic causes, different complaints, and different clinical manifestations. To assess the psychological status of patients used: Gissen somatic complaints questionnaire, Toronto alexithymic scale, the method of studying the type of attitude to the disease Tobol, projective methodology “I am healthy and I am sick”, modified 10-point FPS-R (Bayers-based) subjective pain analysis scale. It was found that in the group of patients with pathology of the TMJ, the main complaint was pain (77.1%), the type of attitude to the disease is mainly alarming (59.5%), and the level of alexithymia is high (78%). Based on the received data on the general condition of the patient, they form a plan of providing comprehensive medical and psychological care, in which during the basic treatment psycho-corrective measures are combined with psychoprophylaxis of secondary disorders of the psychological health of patients.

Currently, titanium plates and screws are widely used to fix bone fragments in maxillofacial surgery. The need for a second operation to remove the metal structure increases the patient's incapacity for work, the economic costs of treatment and the psychoemotional load on the patient associated with anxiety and additional stress. All this has led to the emergence of an alternative method of osteosynthesis using biodegradable plates and screws, which do not have these disadvantages. With all the positive properties of titanium fixators in recent years there has been a large number of publications on the increase in complications after metal osteosynthesis (MOS) using titanium bone plates and screws, which is from 5 to 18 %, therefore, there is a need to remove them after consolidation of bone fragments. The results of the study were the basis for finding ways to obtain the material without metal defect, from which it would be possible to make fixator in the form of plates and screws for the osteosynthesis in maxillofacial region. It was developed biodegradable material of bioactive action (EPU-GAP-LEV) based on polyurethane composition which contains 20 % hydroxyapatite, and 6 % levamisole for osteosynthesis fixator. It was proved effectiveness of EPU-GAP-LEV fixators for osteosynthesis in the treatment of the patients with fractures and deformations of facial skull. Positive results of own clinical researches in early and long terms testified to efficiency and perspective of use of polymeric (including EPU-GAP-LEV) miniplasts in surgical treatment of fractures of facial skull with shift.

the pathology of dental crowding in  mixed dentition period is one of the most common in orthodontic practice. Its prevalence, according to various worldwide scientific sources, reaches 77% and occurs at all stages of the formation of the dentognathic system, sometimes complicating the existing malocclusion. The purpose of our study is to create a rational treatment protocol for patients with dental crowding  according to the facial skeleton growth pattern, as well as to conduct a comparative analysis of the effectiveness of dental crowding treatment according to standard and suggested protocol. A three-year study at NMU O.O. Bogomolets Medical Center  of patients with dental crowding in mixed dentition period(164 people).A total of 328 CBCT slices before and after treatment of patients with crowded teeth were submitted to the overall analysis. The results and conclusions of treatment efficiency analysis were carried out using the proposed treatment protocol with different facial skeleton growth patterns indicate an increase in the quality of treatment of this pathology and a reduction in  treatment terms to achieve the result. The results obtained after 16 months in patients with a horizontal type of growth indicate that the effectiveness of the treatment of CG II patients reached 68.1±1.3%;after 17 months, in patients with a vertical and neutral growth patterns, the effectiveness of treatment of CG III reached 76.7±1.6%, CG I – up to 62.3±0.7%. The algorithm proposed by us allows  to shorten the treatment period by 3-4 months.
