What is canine guidance occlusion?

In canine guidance, the canines act as the primary guidance mechanism during any lateral jaw movement. As the mandible shifts left or right, the canine on the working side contacts and lifts the posterior teeth out of occlusion within fractions of a millimeter. That immediate posterior disocclusion reduces lateral stress on the molar and premolar restorations you are placing, which matters when those restorations are zirconia or PFM crowns carrying full occlusal load.

For restorative dentists and prosthodontists planning crown and bridge cases, canine guidance only works as designed when the lab receives accurate records. Facebow transfer, a properly mounted articulator, and a clear prescription stating the target occlusal scheme are the baseline. Without them, the lab technician is guessing at guidance angles. Dani Dental fabricates restorations from fully mounted cases, and every crown-and-bridge prescription includes a field for occlusal scheme so the technician on your case builds to a stated target, not an assumption.

Distinguish canine guidance from group function: group function distributes lateral contacts across multiple posterior teeth on the working side, which suits some clinical situations but is a different prescription. Submitting cases with an ambiguous scheme leads to remakes. Specifying canine guidance explicitly in your Rx, and confirming the canine rise on your mounted model, eliminates that variable before the case ships.
