Lava™ Zirconia Crowns and Bridges by 3M ESPE combine superior

strength and durability coupled with excellent esthetics to meet

the demands of your patients. Now the Lava™ system is available in 8

shades for natural shade matching. Lava™ zirconia crowns and bridges

utilize an innovative CAD/CAM technology to produce all-ceramic

crowns and bridges on a zirconium-oxide glass-free polycrystalline

base that result in high-strength, reliable restorations with excellent

esthetics and an outstanding marginal fit. Preparations require minimal

removal of tooth structure and conventional cementation techniques.

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 around a 5° horizontal angle.

* No undercuts,  retention grooves, or sharp edges.

* 1.5 - 2.0 mm of occlusal clearance.
