3M’s patented color ion shading technology delivers consistent color. Developed specifically for a consistent color match to VITA Classical shades, Lava Plus High Translucency Zirconia Dyeing liquids are available in each VITA Classical shade plus two bleach shades.
In order for Lava™ Plus Zirconia to obtain its desired optical properties it must allow light to pass with a minimal amount of scattering. Scattering occurs when light strikes structural defects inside the sintered Zirconia. This same microstructure that gives Lava Plus Zirconia its high translucency is also responsible for its high strength and fracture toughness which is a measurement of a material's ability to resist fracture. The average grain size of less than 0.5 µm and the material properties found in Lava Plus Zirconia yields a surface that is also kind to opposing dentition.
