Abstract

Despite the use of Yttria Tetragonal Zirconia Polycrystal (3Y-TZP) in several technical and biomedical applications, the possibility that this material can aged infunction, a phenomenon known as low temperature degradation (LTD), remains a subject under discussion...The aim of this in vitro research was to compare de marginal adaptation of veneered zirconia (Z- CAD HD, Metoxit AG, Tayngen, Switzerland; E-max, IvoclarVivadent), monolithic zirconia (Z-CAD HTL, Metoxit AG, Tayngen, Switzerland), andmetal ceramic CAD/CAM crowns, and to analyse the influence of cementation (Rely XU200, 3M Espe) on the fit of the restorations. It was also analyzed the influence of aging on the marginal fit of zirconia based crowns...
