Lava crowns by 3M ESPE is a type of porcelain crowns. It is made from zirconia porcelain that is one of the strongest all ceramics available today. Lava crowns and bridges combine both strength and durability coupled with esthetics that has eight shades choices for natural shade matching.

A zirconium-oxide glass-free polycrystalline base is used in Lava crowns and bridges. This result in high-strength and marginal fits suitable for both anterior and posterior applications. 3M Lava crowns have a unique coping that is made from a precision CAD/CAM milling system. It can withstand stresses many times greater than those in the mouth. 3M Lava zirconia has over 10 years of clinical history with proven results.

Not all zirconia ceramics are however the same. Zirconia itself can be chemically similar, but may be processed different to attain various mechanical and optical properties. Available ranges of Lava zirconia include Lava Premium, Lava Classic, Lava Essential and Lava Esthetics.
