The  zirconia core allows a much more vital result by eliminating the opacity of a metal substructure.

The core is thin, translucent, and very strong. It can be covered with a layer of opaque for more versatility and control in shade matching.

 

Basic Prepping Guidelines for Lava Restorations

Here a few of the basics for proper Lava prep design considerations:

* A full 360-degree chamfer at a horizontal angle of appr. 5°.

* No undercuts,  retention grooves, or sharp edges.

* 1.5 - 2.0 mm of occlusal clearance.
