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!!!

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
![Page 24: Stable Centrums](https://reader035.vdocuments.net/reader035/viewer/2022062500/56815209550346895dc04a79/html5/thumbnails/24.jpg)
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
