Bond strength of resin cements to zirconia conditioned with primers.
New ceramic primers, which reportedly enhance bonding of resin cements to zirconia, have been marketed recently. The purpose of this study was to compare the shear bond strength of 3 resin cements to zirconia conditioned with 4 ceramic primers. Zirconia blocks were conditioned with 4 different primers (Z-Prime Plus, MonoBond Plus, CLEARFIL CERAMIC PRIMER, and AZ Primer) or no primer (control). The zirconia blocks were placed in a jig, and 1 of 3 resin cements (Multilink Automix, RelyX Unicem, Panavia F 2.0) were mixed, injected into a mold, and light cured. The specimens were tested in shear on a universal testing machine after 24 hours of storage in distilled water. The shear bond strength of the resin cements to zirconia varied based on the type of primer. Z-Prime Plus provided the highest shear bond strength to zirconia, and was significantly greater than the control (no primer) with all 3 resin cements.
