Aim: The aim of the present study was to investigate the shear strength of the bond between feldspathic and heat-pressed ceramic on Co-Cr alloy and zirconium substrate.

Materials and Methods: For the experimental procedure 54 disk-shaped specimens were fabricated from a metal alloy and zirconium, that served as substrates. Group A included 27 Co-Cr alloy specimens fabricated with SLM Technique while Group Β included 27 CAD/CAM zirconium specimens Subgroups corresponding to the veneering material (feldspathic and glass-ceramic) were created within each group.

The bond strength between the substrate and the veneering material and the ultimate strength were measured.

Results and Conclusion: Within the limitations of this study the following could be concluded:

  • The shear bond strength of various veneering materials on metal alloy and zirconium was mainly influenced by the type of substrate.
  • The shear bond strength values of feldspathic ceramic on the metal alloy were superior compared to all other combinations.
  • The higher shear bond strength values were noted for the combination of feldspathic porcelain on metal alloy, with statistically significant differences to glass ceramic materials on the same substrate.
  • Feldspathic porcelain also showed increased shear bond strength on zirconium substrate compared to glass ceramic materials.
  • The shear bond strength values of the two tested glass ceramic materials differed significantly either on metal or on zirconium substrate.
