ABSTRACT
CoCr-cylinders were bonded to zirconia plates (20 mm × 10 mm × 2 mm; n = 8 per group) using four self-adhesive resin cements (one capsule, three hand-mixed) and four resin cements, partly in combination with a tribochemical/silane treatment. All cements were auto-polymerizing. The bonding areas were sandblasted using 110 µm Al2O3. The shear bond strength was determined after 24 h, 30 days, 90 days of water storage (37◦C) and after 12 000 thermal cycles. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Bonferroni post hoc test (α = 0.05).
