Математическое обоснование сбалансированности жевательных мышц по результатам электромиографических исследований

Abstract

The main function of dentogingival protective capsules in contact sports is: good protection of teeth, soft tissues, temporomandibular joint and reduction of the likelihood of brain concussion; besides, they should provide optimal fixation in the oral cavity and maximum comfort of the athlete. However, today more and more researchers are studying the improvement of their quality due to additional opportunities. The aim of the study was to develop and investigate the technology of balancing the optimal state of chewing muscles by means of an individual relaxation device for determining the height of the lower facial part. For the study, we conducted electromyographic studies of 10 athletes who were engaged in boxing at the age of 17 to 22 years. Each of them was made a relaxation device in the form of an individual spoon on the upper and lower jaws, connected together by a spring mechanism (an application for an invention was filed). With the help of chewing movements of the jaw, the patient led the relaxation device for 5,10 and 15 minutes. The main parameters of the study are the activity time [ms], the filling time [Hz] and the activity period (the number of amplitudes], the maximum and minimum values (pV). The results of the research showed that the period of influence of the relaxation device on muscle tone, at which their maximum relaxation in the set of parameters is observed, can be considered as the most favorable (optimal) for the manufacture of a tooth-drop.
