| Research Abstract |
In the present study, brain function activity before and after denture treatment was compared between two groups of subjects of which, one was characterized by the presence of pain and the other, by the absence of pain. Results from such comparison revealed that the removal of pain through denture treatment activates brain function activity. A positive correlation was found between the improved occlusal force attained via complete denture treatment and the activation of Da.
The present study was conducted to identify how changes in the vertical dimension of occlusion affect the sensory perception and activity of the brain in complete denture wearers using an electroencephalogram. Based on their original dentures, two duplicate dentures with different vertical dimension of occlusion (-3 mm and +5 mm) were fabricated. The results suggested that analysis of electroencephalographic data can provide estimates of changes in vertical dimension of occlusion.
