Zirconia Tips and Tricks - Biting Force and Occlusal Thickness

The location of a restoration, and consequently the biting force, is critical to determining the required strength level of a zirconia material.

To avoid fractures, the occlusal thickness must be adjusted to compensate for the strength of the selected zirconia material.
