Abstract
Masticatory function of 10 telescope denture wearers in the Kennedy class II mandible patients was evaluated with electromyography.
Electromyographic activity during mastication with kamaboko and peeled raw carrot was recorded from bilateral masseter and the anterior part of temporal muscles at each interval: Before treatment, immediately after denture insertion and 2, 4, 6, 8 weeks after respectively. Mean of duration, interval and cycle of EMG activities, coefficient of variation andaverage variation were calculated.
The results were as follows:
1. Means of duration and cycle timesd ecreased immediately to 2 weeks after denture insertion.
2. EMG activities during raw carrot chewing became regular immediately to 2 weeks after denture insertion, and within 4 weeks in kamaboko chewing.
These results suggest that telescope dentures would be adapted to stomatognathic system within short period after denture insertion.
