Bond Strength of Resin Cements to Zirconia Ceramic Using Adhesive Primers.

Purpose: To evaluate the influence of adhesive primers on the microshear bond strength of resin cements to zirconia ceramic.

Materials And Methods: Fifty zirconia plates (12 mm × 5 mm × 1.5 mm thick) of a commercially available zirconium oxide ceramic (ZirCad) were sintered, sandblasted with aluminum oxide particles, and cleaned ultrasonically before bonding.
