CAD/CAM resin composite crowns are inexpensive tooth-colored prostheses that have been widely used. However, bonding between CAD/CAM resin composites and resin cements could be difficult since the resin composite is highly cross-linked. There is limited existing data on the resin cements’ bond strength with different monomers to CAD/CAM resin composites. In this study, CAD/CAM resin composite was bonded to an SUS rod with three different resin cements following treatment of the bonding surface using the manufacturer's recommended primer. After storing the specimens in water at 37 °C for 24 h, half of them were tested immediately and half were thermocycled for 10,000 cycles in water for a dwell time of 20 s at 5 and 55 °C. The means of the tensile bond strength and standard deviations were determined for each resin cement and testing condition. The data were compared using two-way ANOVA and Bonferroni's multiple comparison tests at 95% confidence level.
