Abstract
The objective of this study is to compare the microstructural characteristics of two yttria stabilized zirconia (Y-TZP) after grinding and ressintering. For this study, 70 Y-TZP zirconia bars will be obtained and divided into 2 groups: group L (LAVATM, n=35) and group Z (Zirkonzahn®, n=35). Samples will be obtained at a pre-sintered form (T1) and subjected to sintering (T2), grinding (T3)…
