Influence of surface treatment and simulated aging on bond strengths of luting agents to zirconia.

Abstract

Surface treatment, luting agent, and storage conditions significantly influence shear bond strengths to zirconia. Artificial aging significantly reduces shear bond strengths. Airborne-particle abrasion combined with a resin composite containing adhesive phosphate monomers or tribochemical silica/silane coating combined with any of the tested resin composite luting agents provides superior long-term shear bond strength values.
