Electromyographic substantiation of the feasibility of myorelaxing splint in the treatment of tmj dysfunction

Abstract

Our study allowed us to trace and analyze changes in the chewing muscles of patients that occur during the treatment of tempoal-mandibular joint dysfunction (TMJ), and to indicate its effectiveness. In patients with TMJ dysfunction, qualitative and quantitative indicators of electromyography closely correlate with the stages of pathological development and correspond to its clinical manifestations. In this study, for the first time, the relationship between changes in the parameters of the frequency of muscle contractions and the subjective sensation of pain in the area of the specified chewing muscle in patients was analyzed. The purpose of the study is a comparative analysis of the nature and degree of changes in the electromyographic activity of the main and auxilliary chewing muscles in patients with TMJ dysfunction before and after the use of myorelaxing spleen. Materials and methods. A five-year study on patients with TMJ dysfunction (109 people). The general analysis provided 1,024 electromyograms before and during the stages of treatment. The results of the analysis on the effectiveness of the use of myorelaxation tires in the treatment of TMJ dysfunction can improve the quality of treatment of this pathology. The results obtained after 12 months indicate that the effectiveness of treatment in patients with KG I (with the lowest intensity of symptoms of TMJ dysfunction) reached 89.1±1.3%, and in those with KG II – up to 78.3±1.3%, respectively.
