3M™ Lava™ Premium Zirconia Crowns
3M™ Lava™ Premium system is based on a unique 3M™ shading technology, meaning that its color is not on the surface but comes from within. This unique technology used in the Lava™ Premium Dyeing Liquids also helps to preserve translucency after shading, without compromising strength.
Lava™ Premium High Translucency All-Zirconia Crown (A2)
Lava™ Premium zirconia is the beautifully durable material of choice.
1. Compared to other shaded zirconias.
2. Data on file.
Single Crown 3-unit bridge
Curved and long-span bridge Anterior adhesive bridge
Primary Crown / telescope Build-up for two-piece abutment
1. Splinted crowns up to 4 units.
2. 5+ unit bridges (up to 48 mm) with a maximum of two pontics next to one another in the posterior area and a maximum of four pontics next to one another in the anterior area.
3. With a maximum of 1 pontics at the position of a premolar or incisor.
4. Tests have proven: Lava™ Zirconia shows a sufficient strength for this indication. However, this type of indication overall can have a higher failure risk due to de-cementation and secondary caries regardless of manufacturer. Please refer to national and regional dental associations for more information.
In a field evaluation, Lava™ Premium High Translucency Zirconia was put to the test with dentists and dental labs alike.
Dental lab reviews showed Lava™ Premium zirconia to have the best overall esthetics, with significantly higher all-zirconia crown translucency than leading competitors without compromising strength. It's the ONLY system that matches the VITA® Classical A1-D4 and bleached shades.
Dentists involved in the evaluation said Lava™ Premium High Translucency Zirconia delivers the best zirconia esthetics ever, with more options for all-zirconia or layered restorations.

* Lava™ Premium is internationally known as Lava™ Plus
Since its introduction in 2001, Lava™ Zirconia has become a huge success story. Millions of restorations have been produced and Lava™ Systems are running in over 40 countries around the globe.
Lava™ Zirconia is one of the best investigated materials on the market with over 100 studies published by researchers worldwide. Lava™ stands for high-strength restorations with outstanding marginal fit and excellent aesthetics. Due to its proven reliability, 3M™ grants for 15 years from the date of placement that copings or substructures made out of Lava™ Zirconia will not break.
If fabricated by an Authorized Lava™ Milling Center or on approved Lava™ Equipment in strict compliance with approved indications and instructions for use for Lava™ Crowns and Bridges. Only approved indications for Lava™ Zirconia are covered and the warranty does not cover any breakage resulting from accidents or misuse. Additional costs such as the cost of preparation and veneering are also not covered.
