Excellent shade match for all-zirconia
Lava™ Plus High Translucency Zirconia
Lava™ Plus High Translucency Zirconia system offers all-zirconia restorations that exhibit accurate color match without compromising translucency or strength, so that you can achieve your esthetic demands. Lava zirconia is well-known for its outstanding reliability, precision and beauty for crown and bridge restorations. With extensive studies and millions of restorations placed since 2001, Lava Zirconia has been clinically proven.
Predictable Color Match – An A2 is an A2
3M's patented color ion shading technology delivers consistent color. The Lava Plus zirconia shading system provides an excellent color match to VITA® classical shades and a direct conversion to the VITA SYSTEM 3D-MASTER® shades—so the results will match what you prescribe.

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. The high quality processing of Lava™ Zirconia minimizes these effects. Lava™ Plus Zirconia will sinter to a highly dense polycrystalline microstructure with an average grain size of below 0.5µm.
This allows Lava Plus Zirconia to match the translucency of e.max when milled to the minimum thickness (PDF, 34 KB).
Lava™ Plus may be used anywhere, for any indication. The material allows a 0.5 mm minimum wall thickness, requiring 3X less occlusal preparation than lithium disilicate glass ceramic because of its 3X greater strength.*
* Data on file
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.
Lava™ Plus Zirconia's unique microstructure and chemical formulation also resists degradation that can be observed in zirconia ceramics when they are exposed to elevated temperatures in humid environments.
The higher the aging stability, the lower the monoclinic phase content at the surface of a zirconia after hydrothermal treatment (PDF, 112 KB).
If minor intra-oral adjustments are necessary, use a fine diamond bur with water-cooling and continue with a standard rubber polisher set for ceramic dental materials. To achieve a high-shine finish, use a diamond polishing paste and a suitable polishing brush.
RelyX™ Unicem 2 Cement has the best shear-bond strength to dentin and excellent shear-bond strength to enamel, providing a long-lasting and secure restoration.
