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.
对15名佩戴全口义齿的患者和8名天然牙列的成年受试者的咬肌和颞肌前束的积分肌电图（IEMG）活动进行了分析。在正中牙合位进行最大自主紧咬和吞咽唾液时，使用双极表面电极记录IEMG。佩戴全口义齿的患者在最大自主紧咬时，两块肌肉的IEMG活动明显低于天然牙列的受试者。在吞咽唾液时，两组中两块肌肉的活动相似。这对于全口义齿佩戴者口腔颌面部系统不同结构功能状态的维持可能具有重要的临床意义，因为吞咽过程是一种每天重复约600 - 2400次的24小时功能。
