  • Title: Comparative electromyographic study of elevator muscles in patients with complete dentures and natural dentition.
    Author: Miralles R, Berger B, Ide W, Manns A, Bull R, Carvajal A.
    Journal: J Oral Rehabil; 1989 May; 16(3):249-55. PubMed ID: 2746412.
    Abstract:
    An analysis of integrated electromyographic (IEMG) activity of masseter and anterior temporal muscles was undertaken in fifteen patients with complete dentures and eight adult subjects with natural dentition. Bipolar surface electrodes were used for IEMG recordings during maximal voluntary clenching and saliva swallowing in the inter-cuspal position. The IEMG activity of both muscles during maximal voluntary clenching was significantly lower in patients with complete dentures than in subjects with natural dentition. During saliva swallowing the activity in both muscles was similar in both groups. This may have a great clinical significance in the maintenance of the functional state of the different structures of the stomatognathic system in complete denture wearers, since the process of swallowing is a 24-h function repeated about 600-2400 times each day.
