In terms of scientific research, especially in the enhancement and application of new technologies of subjective quality assessment methods of prosthetics is not enough, therefore, the most objective and informative electromyography recognized the essence of which consists in registration of biopotentials of the masticatory muscles. No complaints on the pain while chewing even enough solid food, good fixation and stabilization of prostheses, phonetics recovery suggest the establishment of a new functional level of dental system, the development of a consistent pattern of chewing. Objective electromyographic evaluation of the quality of prosthetics has confirmed the validity of subjective tests. The purpose of the study to establish the extent of functional disorders before and after prosthetic. In electromyographical studies of the nature of the recovery of mastication function can be traced to a pronounced tendency for normalization. It is to increase the amplitude of the currents during the period from the date of imposition of the prosthesis, after 1 month and a year after prosthetic treatment (from 350 to 500 and 560 mV). The characteristic feature of the perfect regulation of muscular activity is the dissection of the structure of the records, that is, alternating bursts of activity with periods of rest, and reflex change sides chewing for one of the chewing period. Most revealing is the ratio of excitatory and inhibitory processes - the coefficient "K". The obtained data objectively confirm the validity of the assessment of the quality of prosthetics using subjective tests used in massive prosthetics.
