Effect of surface treatments on the bond strength of a zirconia-reinforced ceramic to composite resin Efeito de tratamentos de superfície sobre a resistência de união entre cerâmica reforçada por zircônia e resina composta
The objective of this study was to evaluate the tensile (σt) and shear bond strength (σs) of a glass-infiltrated alumina-based zirconia-reinforced ceramic (IZ Vita In-Ceram Zirconia) to a composite resin, testing the hypothesis that silica coating (SC Cojet, 3M-Espe) produces higher bond strength values than other ceramic surface treatments. Specimens were fabricated and tested according to the...

OBJECTIVE To evaluate the bond stability of resin cements when luted to glass-reinforced alumina and zirconia CAD/CAM dental ceramics. STUDY DESIGN Eighteen glass-infiltrated alumina and eighteen densely sintered zirconia blocks were randomly conditioned as follows: Group 1: No treatment; Group 2: Sandblasting (125 µm Al₂O₃-particles); and Group 3: Silica-coating (50 µm silica-modified Al₂O₃-...

OBJECTIVES This study evaluated the effect of three different surface conditioning methods on the bond strength of a Bis-GMA based luting cement to six commercial dental ceramics. METHODS Six disc shaped ceramic specimens (glass ceramics, glass infiltrated alumina, glass infiltrated zirconium dioxide reinforced alumina) were used for each test group yielding a total number of 216 specimens. T...
متن کاملLifetime of alumina- and zirconia ceramics used for crown and bridge restorations.
The lifetime of a ceramic is dependent on the presence of incidental cracks and their gradual propagation under the conditions of the oral cavity. The objective of this study was to examine the long-term strength of glass-infiltrated alumina- and various zirconia ceramics currently used in CAD/CAM systems to manufacture crown and bridge frameworks. Fracture mechanics were applied to determine c...
