Making yttria-stabilized tetragonal zirconia translucent [PDF]

Dental Materials, 2014
The aim of this study was to provide a design guideline for developing tetragonal yttria-stabilized zirconia with improved translucency.The translucency, the in-line transmission in particular, of 3mol.% yttria-stabilized tetragonal zirconia (3Y-TZP) has been examined using the Rayleigh scattering model.
