Abstracts
Activity o f anterior and posterior temporal muscles was electromyographically examined in thirty complete denture wearers at
the denture insertion and after a 2 — 5 week period o f denture wear.
Muscle activity was recorded by surface electrodes on a 4 channel poligraphic apparatus during maximum voluntary biting in maximal intercuspal and retruded occlusal positions, as well as in incisal and left and right occlusal positions. Activity o f both, anterior and posterior temporal muscles increased after the 2 - 5 week period o f
denture wear, compared to the insertion stage. The biggest increase o f anterior and posterior temporal muscle activity was in maximal intercuspal and retruded occlusal positions (p < 0.01 for RAT, LA T, LPT, p < 0.05 for R P T in maximal intercuspal position; p < 0.01 for RAT, LA T, RPT, p < 0.05 fo r L P T in retruded occlusal position). This could be attributed to the dominance o f voluntary central command over the pool o f motoneurons o f the V motor nucleus with bilateral distribution o f voluntary muscle efforts in these positions. The increase o f anterior and posterior temporal muscle activity was not o f great significance, or none at all in incisal and left and right occlusal positions (p < 0.05 for R A T and LPT, p > 0.05 for L A T and R P T in incisal position; p < 0.05 for RA T, RPT, LPT, p < 0.01 for L A T in the left occlusal position; p > 0.05 for LA T, RAT, L P T and R P T in the right occlusal position). This could be attributed to the greater involvement o f peripheral sensory receptors and consequent prolonged establishment o f neuromuscular feedback mechanisms. Period o f neuromuscular adaptation to the dentures is prolonged considering incisal and left and right occlusal positions, compared to the maximal intercuspal and retruded occlusal positions .
