Why use Centric Relation (CR)? I like to call CR the eighth wonder of the world as described by my good buddy, Lenny Hess.
Centric Relation represents the only stable jaw-to-jaw relationship.
CR also gives us the opportunity to provide the only truly interference-free occlusion. If there’s a CR-MI slide from a stable joint-seated position, we can also provide an occlusal scheme at an infinite number of VDO’s. So, why use CR? You should use CR if you want to maintain your predictability.
