The aim of the study was to assess the efficacy of audiodiagnostics in dysfunctional TMJ disorders. Thirty-four patients were included in the study. The analysis of phonograms revealed correlation of adverse sound effects with varying degrees of internal TMJ-disorder seen by MRI imaging. The study results confirm the advantages of electronic registration of TMJ sound phenomena.
To date, there is no consolidated opinion regarding the terminology and classification of bruxism. The following terms are used for determination of unconscious strong compression teeth: “effect Karolyi”, “stridor dentium”, occlusal neurosis, odonterizm, “bruksomaniya”, “parafunctional activity of masticatory muscles”. Because of the disease nature the polyethiologic symptom group is develops that complicates the disease representation. The authors are recommend the usage “bruxism” term in everyday practice and as the most well-established and popular in the medical practice. The primary point of our study was identification of the pathognomonic parameters on electroencephalogram in patients with bruxism. As result of the study it was identified that the border type of EEG was registered statistically higher in pa-tients with parafunctional activity of masticatory muscles than in control group. The results are consistent with global trends, in respect that neuroscientists are systematize bruxism to “parasomnias”, (according to ICD 10) which are characterized by minor changes in the basic rhythm which were identical to findings that we revealed in the study group.
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.
Aim of the present study was to evaluate the effectiveness of prosthodontic methods of treatment based of functional diagnostic of patients with increased dental attrition Methods. We have examined 35 patients at the Smolensk State Medical University Hospital: 20 patients with increased dental attrition and 15 patients who didn’t have any sign of functional disorders of dentoalveolar and musculoskeletal system. The main group was divided into two subgroups. In the group 1 (11 patients) required a prosthodontic therapy included individual wax-up of future prosthetic construction based on data of functional diagnostic. An electromyographic study was conducted before and one month after treatment for determination of the effectiveness of treatment methods. Results. Analyzing and comparing the data of the electromyographic study 1 month before and after treatment of patients of the 1 group have shown 93,1 % effectiveness of the treatment and the control group. The results of the study show that such occlusion is optimal for the muscles and temporomandibular joint. Conclusion. Dental treatment of increased attrition of teeth based on functional diagnostic contributes to the normalization of muscles activity. Moreover it allows to protect teeth from attrition and providing effective rehabilitation of patients.
