The 3M™ ESPE™ Lava™ Crowns and Bridges system is an innovative CAD/CAM technology using a zirconium oxide base. The durability and esthetics of Lava restorations represent the optimum in all-ceramic systems. Preparations require removal of less tooth structure and cementation can be accomplished using proven, conventional techniques. Colorable frameworks that are thin and translucent ensure a natural and vital appearance. Available for crowns and up to six-unit bridges that offer strength, stability and outstanding marginal fit.

Patented substructure shading system available in 8 shades Zirconia provides proven high strength performance Precision CAD/CAM system for outstanding fit Indicated for anterior and posterior crowns and bridges Five years of clinical history and proven results Natural translucency and unmatched esthetics More than 25 years of zirconia research and technology

"Our research showed that the marginal fit of Lava bridges was as good as
metal-ceramic bridges. The zirconia substructure does not distort when
firing the veneering porcelain, unlike metal substructures."
