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!!!

Not Feeling too well.

Balancing Guides Are Protective

Balancing guide maintains mutualcontact.

Working guide progressively isolates inclines and “rocks” the teeth.

All the same radius

OA to soften the guide

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

Thanks for your Interest!!

Centrums Really
