Sažetak
The aim of this study was to evaluate the effect of gradual isometric bite force on electromyogram of the temporal and masseter muscles during determined functional movements, such as biting at different clenching levels i.e. maximal (EMG-1), middle (EMG-2) and minimal (EMG-3), and during speech movements such as reading aloud an unfamiliar text (EMG-4). Symmetry was examined, as it is generally accepted that in a functionally normal and balanced occlusion bilaterally symmetrical EMG activity should occur. Very high values of asimmetry indices were obtained in this study (-65.04% to +67.72%), which was associated to the very strong influence of visual feedback except in the EMG-4, where asimmetry indices were lower than 20%.
