Objective. To describe the basic predictors of developing dysfunction of temporomandibular joint (TMJ) in patients with maxillary dental anomalies. Materials and methods. An open, prospective, controlled clinical experimental study was carried out; 250 patients aged 18 to 35 (mean age 23.5 2.6 years) with maxillary dental anomalies including 134 persons with temporomandibular joint dysfunction and 116 with normal articular function were examined. Results. A multidimensional disperse analysis permitted to conclude that an extremely high (95100 %) probability of occurring temporomandibular joint dysfunction is determined with the presence of combination of two and more functional disorders with a complex of other (occlusive and cephalometric) preclinical markers of dysfunction; a high (7595 %) probability of development when one functional disorder is associated with a gnathic form of dentition occlusion anomaly; a medium degree (4575 %) of probability of occurring dysfunction with the presence of gnathic form of dentition occlusion anomaly with roentgenological changes in TMJ and the absence of functional signs; a low (1545 %) probability when detecting a dentoalveolar form of occlusion anomaly or dentition anomaly combined with roengenological changes in the joint and the absence of functional disorders; a very low (015 %) probability of dysfunction development with the presence of congested position of incisors, anomalies of separate teeth position in the sagittal plane in the frontal part and the absence of functional disorders. Conclusions. The knowledge of the above-mentioned predisposing factors (signs) of the disturbance of the joint function can be used as an instrument for prediction of the probability of developing the temporomandibular joint dysfunction in patients with maxillary dental anomalies.

Aim of the present study was to evaluate the parameters of computer stabilometry of patients with increased dental attrition. Methods. We have examined 50 patients with increased dental attrition, 45 patients who didn’t have any sign of functional disorders were the control group. The stabilometric examination was carried out using the system for diagnosis and rehabilitation of the musculoskeletal system and the balance function “MBN-Stabilometer” (MBN, Moscow). Inclusion criteria were presence of increased dental attrition 2,3 Bushan’s rate, normal occlusion (Angle’s occlusion classification), age of 35 to 54 years. Exclusion criteria were oral mucosal diseases, periodontitis, temporomandibular joint dysfunction, dental-anomalies and deformities, taking medicine that affect muscle tone; somatic diseases in the acute stage. Results. Analyzing and comparing of the data of the stabilometric study of patients of the main group and the control group showed statistically significant differences in the parameters were obtained. Conclusion. Utilization of computer stabilometry should reveal functional disorders of postural systems, as well as determine the most rational tactics of complex treatment of patients with increased dental attrition.

Research background. The imbalance between the jaw and neck muscle activity occurs as a compensatory mechanism in order to stabilize the jaw and neck structural parts in temporomandibular joint (TMJ) disorders (Ries et al., 2008). Changes occur in posture control system if any biomechanical unit varies (Ritzel et al., 2007). One system compensates the unusually active other body system in upper cross syndrome (UCS) (Tharcher et al., 2011). This syndrome is characterized by shortened upper trapezius, pectoralis major and romboids and week middle and lower trapezius, serratus anterior and deep neck flexors (Moore, 2004; Tharcher et al., 2011). Thus, it is believed that there may be a direct link between the upper cross syndrome and temporomandibular joint dysfunction. Purpose. Explore relationship between temporomandibular joint dysfunction and upper crossed syndrome in women. Methods. Thirty female volunteers participated in the study, and they were divided into groups according to trigger points in the shoulder and neck muscles: group 1 – painful shoulder and neck muscles (32.65 ± 12.34 years), group 2 – painless shoulder and neck muscles (34.5 ± 10.95 years). Survey was carried out assessing TMJ function during observation, palpation, evaluation of the sagittal craniovertebral angle, the neck and shoulder muscle length, strength, pain and deep neck muscle endurance was examined. Results. It was found that TMJ function was strongly associated with the UCS: trapezius pain as well as upper trapezius and scalenus length. TMJ disorders were associated with headache in both groups. Weak connection between deep neck muscle endurance and TMJ dysfunction was identifed. Conclusions. TMJ mobility is partly related to UCS, and TMJ functional disorders related to headache and sagittal craniovertebral angle. UCS specifc changes, such as pectoralis muscle length changes and impaired deep neck muscle endurance are not related to TMJ dysfunction.Keywords: temporomandibular joint, the upper crossed syndrome, muscle length, headache.

The prevalence of dysfunction of the temporomandibular joint, especially in people aged 18-60 years, reached 95-98 % among all dental applications. The course of the pathology is usually hidden, with periodic recurrences and has a long nature, which is accompanied by a decrease in overall quality of life. Treatment of this pathology of the temporomandibular joint is a set of complex therapeutic, orthopedic and psychological measures. The literature describes many ways to treat temporomandibular joint dysfunction, one of the modem ones is the use of occlusal splints, which allow to change the position of the mandible, diagnose and eliminate musculoskeletal dysfunction of the temporomandibular joint. The aim of the study was to determine the effectiveness of treatment of musculoskeletal dysfunction of the temporomandibular joint with occlusal splints according to axiography. 274 patients aged 18 to 65 years were diagnosed with temporomandibular joint pain syndrome before and after treatment. All patients with signs of temporomandibular joint dysfunction before treatment had a violation of the trajectory of the mandible (deviation is 68.7 %, dyslexia is 31.3 %). When opening and closing the mouth, asymmetrical shifts of the lower jaw to the sides of more than 2 mm (deviation from the midline is more than 2 mm) were observed. After treatment with occlusal splints there was an improvement in the trajectory of opening and closing the mouth: the number of patients with a violation of the trajectory decreased by 89.1 %, and the displacement of the mandible during opening and closing the mouth in 92.4 % of patients decreased on average to 0.9 mm. When analyzing the movements of the mandible in the sagittal plane in 79 % of cases, deviations of the trajectory of the mandible were detected. After treatment with occlusive muscle relaxation splints, elimination of violations of the trajectory of the mandible in the transverse plane was noted in 93.4 % of cases, reduction of displacement to 0.9 mm in 78.1 % of patients. The trajectory of the mandible in the sagittal plane improved in 80.1 % of patients, normalization of the position of the mandible relative to the neuromuscular trajectory was achieved in 93.4 % of clinical cases. According to the analysis of parameters, such treatment should be considered effective.

Subject. The relevance of the study is associated with the widespread prevalence of diseases of the temporomandibular joint and masticatory muscles. The large amount and inconsistency of literature data, the lack of generally accepted terminology and diagnostic criteria, and the variety of treatment methods proposed by various authors lead to difficulties in the choice of treatment tactics encountered by the dentist in everyday practice in treating patients with temporomandibular joint pathology. The goal is to study the available literature data on the prevalence and structure of clinical manifestations of functional disorders of the temporomandibular joint. Methodology. The study was conducted on the basis of a search and study of scientific publications on the epidemiology of clinical manifestations of functional disorders of the temporomandibular joint in the databases PubMed, eLibrary, Scopus, Web of Sciens, Medline. The selection of materials was carried out by keywords. Results. The review presents the scientific data of various authors on the epidemiology of the clinical manifestations of dysfunctional disorders of the temporomandibular joint. The most characteristic objective signs of the temporomandibular joint dysfunction syndrome are: “noise” phenomena in the joint during movements of the lower jaw, pain during palpation of the masticatory muscles, restriction of opening of the mouth, deviation during opening of the mouth, bruxomania, displaced position of the lower jaw relative to the upper (transverse, medial distal), the presence of otological symptoms (pain and / or a feeling of stuffiness in the ears), a burning sensation, tingling, tingling, or pain in the tongue. Conclusions. A study of the literature over the past 15 years has revealed a wide variation in the prevalence of clinical manifestations of functional disorders of the temporomandibular joint, which does not allow an unambiguous conclusion about the epidemiology of its dysfunction.
