Assessment of the bioelectric activity of the masticatory muscles in orthopedic treatment with partial removable plate prostheses

Relevance. According to a number of authors, it is known that full adaptation to complete removable dentures occurs within 3 months [3-5, 9]. The main criterion for patients getting used to removable dentures is the synchronization of the work of the masticatory muscles and, as a consequence, the normalization of the chewing function. The aim of the study was to evaluate the bioelectrical activity of the masticatory muscles in patients using the CSPP.Materials and methods. In patients of the control (n = 23) and main (n = 63) groups, electromyographic examination was performed using the electroneuromyographic system "Synapsis" (Neurotechnology, Russia). Registration of the bioelectric activity of the chewing muscles was carried out directly on the day of applying the prostheses, after 1 and 3 months, respectively.Results and discussion. The electromyographic indices of the masticatory muscles in the patients of the control group decreased within one month after the treatment and amounted to 231 ± 18.2 μV for the right and 229 ± 16.1 μV for the left proper chewing muscles. The values were also reduced for the right and left temporal muscles - 228 ± 15.2 μV and 225 ± 24.1 μV (p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
