| Research Abstract |
Two complete dentures with different vertical dimensions (normal and 3 mm decrease) were prepared. Bite force and electroencephalogram (EEG) were evaluated using two dentures. Significant reduction of occlusal force was observed between normal to 3mm decreased dentures. Emotional indexes were divided into the negative (stress and depression) and positive indices (joy and relax). By the change of vertical dimension, the negative index was significantly increased and the positive index was significantly decreased after gum chewing (p<0.05). Brain activity were increased after gum chewing, but no significant difference was observed (p> 0.05). This study indicated that vertical dimension of denture was suggested strongly influence to brain activity and emotion.
