Lava™ Crowns and Bridges are made from zirconium oxide (zirconia) and are suitable for anterior and posterior applications for up to 4 units in length without any compromise of the lifespan of the restoration. Zirconium oxide combines natural appearance with exceptional strength. The fracture strength of a zirconia crown is many times higher than that of the conventional ceramic materials.

Lava™ Crowns and Bridges from 3M ESPE utilize an innovative CAD/CAM technology for producing all-ceramic crowns and bridges on a zirconium-oxide, glass-free, polycrystalline base, resulting in high-strength, reliable restorations with excellent esthetics and outstanding marginal fit. Preparations require minimal removal of tooth structure, and cementation can be accomplished using proven, conventional techniques.
