Feeling Better, No noxious guide

Our supposition at this time Working side guides can be noxious stimuli. These guides may provoke grinding, bruxing movements. These movements are stressful to the muscles of mastication and the face. The movements eccentrically load teeth and dental restorations. These movements can accelerate the failure of teeth or dental restorations.

Our supposition at this time Centrum loading results in the most balanced and concentric muscle effort. There is a diminished tendency to grind or brux when balanced centrums are available to clench. The Most Stable Occlusion for Restoration is Centrum Based
