Abstract
The aim of this study is to evaluate the effect of annealing after grinding on the surface properties, crystalline phases and on the flexural strength of two different zirconia Y-TZP (yttria partially stabilized tetragonal polycrystalline zirconia) systems. Y-TZP bars for core (Group Z) and for full contour (monolithic, Group MZ) will be distributed in 6 subgroups (n = 18) according to th…
