All Zirconia is not alike!

Not all Zirconia is a like. Yes, Zirconia can be chemically similar, but once processed the mechanical and optical properties can be significantly different. Lava™ Zirconia has now been commerically available for 10 years.

Studies and science

Material Strength

3-point bending test in water

Material strength was determined on polish bars in a 3-point bending test in water.

In this study the higher strength of the Lava™ Zirconia could be related to less intrinsic flaws.

This is a direct outcome of 3M ESPE's Lava™ Zirconia material processing expertise.

Marginal Fit

This study evaluated the vertical marginal gap of zirconium-oxide copings from contemporary CAD/CAM systems.

Zirconium-oxide copings were milled using various systems and compared to control cast Copings (n=10). Ninety polyvinylsiloxane impressions were made of a master metal die exhibiting a 1mm heavy chamfer preparation finish-line. TypeIV stone dies were scanned, finish line detected, and copings with 50µm cement space 1mm from finish line were fabricated. Control copings were fabricated using the lost wax technique. Standardized digital photographs of each coping were taken on the metal master die and measured with ImageProExpress to obtain the mean vertical marginal gap in microns.

 

Translucency

Photo Radiometer Measurement

The purpose of this in vitro study was to evaluate the translucency of Zirconia copings for single crowns fabricated using different CAD/CAM systems. High translucency requires a dense, homogeneous material. Translucency also depends on the wall thickness: Lava™ offers the strength and precision that allows to go down to 0.3 mm wall thickness in the anterior region. 0.3 mm Zirconia copings showed the highest translucency.
