The objectives of this study were (1) to evaluate the bond strength of four resin materials with various chemical compositions following the manufacturers’ instructions only and (2) to test their durability in dry and thermal aged conditions when they were bonded to zirconia ceramic. Four types of resin materials namely, Panavia F 2.0, Multilink, SuperBond and Quadrant Posterior Dense, were attached to the disc-shaped zirconia ceramics (LAVA, 3M ESPE) using polyethylene molds and polymerized accordingly after the ceramics were wet ground finished and ultrasonically cleaned. The specimens were randomly divided into two groups for ageing conditions. While the dry groups were tested immediately after attachment of the resin cement, the other specimens were subjected to thermocycling (×6,000, 5–55°C). Bond strength results were significantly affected by the storage condition (p < 0.001) and type of resin (p < 0.001; analysis of variance). Panavia F 2.0 showed the highest bond strength results under dry conditions (9.6 ± 4.1 MPa). When manufacturers’ instructions of the resin cements were followed, no adhesion (0 MPa) was achieved on the zirconia after 6,000 thermal cyclings including Panavia F 2.0.
