  6. So, what is a centrum? A central point of contact surrounded by a fully balanced area of function. Look at the white dot, not the ink!!!

  10. Balancing Guides Are Protective Balancing guide maintains mutual contact. Working guide progressively isolates inclines and “rocks” the teeth. All the same radius

  11. OA to soften the guide

  12. PGA in service

  13. Feeling Better, No noxious guide

  14. 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.

  15. 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

  16. Thanks for your Interest!! Centrums Really Work!!! Ron Presswood, DDS
