Effects of Various Chairside Surface Treatments on Zirconia-Resin Cement Bond Strength
Introduction: Various surface treatments have been used to improve the adhesion of resin cement to zirconia restorations. The present study aimed to investigate the effects of different surface treatments on the bond strength of resin cement to zirconia (Y-TZP) in clinical practice. Methods: thirty square Y-TZP samples were classified into three groups of 10, including group SB (50 µm sandblast...
متن کاملEffect of zirconia surface treatments on the shear strength of zirconia/veneering ceramic composites.
Aim of the investigation was to assess the effect of different surface treatments on the bond strength of veneering ceramics to zirconia. In a shear test, the influences of polishing, sandblasting, and silica-coating of the zirconia surface on bonding were assessed with five different veneering ceramics. In addition the effect of liner application was examined. With one veneering ceramic, the i...
متن کاملAssessment of Different Surface Treatments Effect on Surface Roughness of Zirconia and Its Shear Bond Strength to Human Dentin
Aim of the study: The aim of this study was to assess the different surface treatments effect of yttrium oxide partially stabilized tetragonal zirconia polycrystal (Y-TZP) dental ceramic on its surface roughness and shear bond strength to dentin. Surface topography of zirconia was studied with atomic force microscopy AFM. Materials and Methods: A Total of 35 discs of zirconia dental ceramic of ...
