7 Electromyographic study on the effect of relining removable partial dentures

Abstract

We used electromyography to evaluate the effect of relining removable partial dentures. Electromyograms (EMG) of the bilateral anterior temporalis and masseter muscles were recorded on eight patients together with mandibular kinesiograph (MKG) motions during mastication, tapping and clenching before relining and for two weeks after. The coefficient of variance (CV) for the EMG parameters decreased after relining while EMG bursts during clenching and mastication increased. The results showed that the effectiveness of denture relining was confirmed by electromyography.
