3M™ ESPE™ Lava™ PFZ and fully milled zirconia restorations
LAVA is indicated for anterior or posterior crowns and for 5+ unit bridges (maximum span 48mm) with a maxium 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 and can be cemented with traditional crown and bridge cements.
A special Vita-shading system and control of the processing steps ensures the high quality and brilliant translucency of Lava zirconia frameworks - characteristics that are vital for the aesthetic success of this system versus other brands.
Zirconia materials have varying levels of quality depending on the individual manufacturer's process, although they are chemically similar.
These qualitative differences are based on four basic processing parameters for zirconia, which will affect its performance in the mouth:
-
Differences in the zirconia powder with respect to grain sizes and utilised additives have an impact on the long-term stability as well as translucency of the restoration.
-
The process of pressing can be accomplished by different procedures and under different conditions, influencing marginal fit, strength and translucency.
-
Third, the pre-sintering conditions depend upon an optimised temperature, and are important for the strength of the pre-sintered material and affect its millability.
-
Last but not least, the colouring of the zirconia has an impact on marginal fit, strength and translucency. In the 3M ESPE process, Lava zirconia is coloured by colouring ions which diffuse into the zirconia material and are incorporated in the structure during the final sintering step, a process leading to the high strength of Lava zirconia.
SCDL is now a globally authorised 3M™ ESPE™ Lava™ product provider and restorations are produced in our brand new manufacturing facility in Hong Kong. Each restoration has a certificate of authenticity from 3M ESPE.
