Electromyographic studies of patient adaptation to dentures

Abstract

Using electromyograpy, I evaluated the adaptation of patients to recently placed dentures. Electromyograms (EMG) of the bilateral anterior temporal and masseter muscles were recorded in five patients together with mandibular kinesiograph (MKG) motions during mastication at the time of insertion of new dentures and for four weeks thereafter. The same recordings were made for patients who had dentures that had been in use for some time. EMG bursts during mastication were recorded before and after tooth contact, and duration and integrated values were measured. The results suggested that EMG time parameters and burst activities were effective factors in evaluating patient adaption to dentures.
