Abstract
Because of the equivalent or higher bending strength, hardness, and toughness compared with yttria partiallystabilized zirconia, Ce-TZP/Al2O3 nano-composites (NANOZR) have been developed and are commercially available for frame and abutment materials. In this study, using four types of adhesive resin cement, we evaluated the bond strength and adhesive durability between titanium and two types of NANOZR. The two types of NANOZR (medium- and pre-sinter) were made by sintering the materials with low density after cutting to a higher density at different temperatures. Sand-blast treatment of the adhered surface of the medium- and pre-sinter specimens was performed using alumina particles of 50 μm in diameter at a pressure of 0.2 MPa, and ceramic or zirconia primer treatment was performed. Sand-blast treatment of the titanium surface was performed at a pressure of 0.4 MPa, and metal primer treatment was performed. Thereafter, they were adhered using each type of adhesive resin cement. For the shear bond strength test, some specimens were left in air at 37°C for 24 hours (NANOZRNANOZR, titanium-titanium, titanium-NANOZR specimens), and the others underwent 10,000 thermal cycles of repetitive immersion in distilled water at 4°C and 60°C for one minute (titanium-NANOZR specimens only). The values obtained were statistically tested (ANOVA, Fisher’s PLSD test, α=0.05). The bond strength between titanium and C-Pro NANOZR using resin cement, considering the bond strengths of NANOZR-NANOZR and titanium-titanium, was influenced by the bond strength between the resin cement and titanium. Pre-sinter specimens showed a significantly higher value than medium-sinter specimens, and excellent adhesive durability. Furthermore, resin cement containing phosphoric ester monomers showed a significantly higher value.
