Interaction of zirconia primers with yttria-stabilized zirconia surfaces

Dental Materials, 2016
Recently several zirconia primers have been introduced to mediate bonding of dimethacrylate resins to yttria-stabilized zirconia frameworks (Y-TZP). The aim of the study was to evaluate the changes in surface chemistry of Y-TZP frameworks induced by zirconia primer treatments.Polished Y-TZP discs (Lava, 3M ESPE), ultrasonicated for 10min in ethanol ...
