[Use of biological feedback in persons with complete new dental prostheses during the initial period of functional adaptation].
Adductor muscles muscular tone of new complete denture wearers in the period of initial functional adaptation was investigated as well as the use of visual feedback with EMG method for more efficient use of dentures. Thirteen persons of 63 years average were investigated. Action potential of masseter muscle surface layers and pterigoid muscles anterior layers on both sides were registered. Subjects were instructed how to adjust the mandible from the rest position to the full contact with upper denture teeth and to keep it that way for 5 minutes, 3 times a day. Intensity of measured muscle activity was controlled immediately after denture insertion as well as 7, 14 and 21 days after insertion. The greatest amplitude values of all of four examined muscles were registered after denture insertion. Expected changes due to the use of visual feedback had favorable effect on muscular tone lowering during the following period. Maximal therapeutic tone was reestablished.
