Influence of various airborne-particle abrasion conditions on bonding between zirconia ceramics and an indirect composite resin material.

Statement Of Problem: Indirect composite resins (ICRs) have been suggested as veneering materials for implant-supported zirconia-based fixed dental prostheses; however, obtaining a durable bond between the zirconia ceramic and the ICR is a challenge.

Purpose: The purpose of this in vitro study was to evaluate the influence of airborne-particle abrasion conditions on the bond strength between 2 kinds of zirconia (yttria-stabilized tetragonal zirconia polycrystal [Y-TZP] and ceria-stabilized tetragonal zirconia/alumina nanocomposite [Ce-TZP/A]) and an ICR.

Material And Methods: Zirconia disks were prepared by using computer-aided design and computer-aided manufacturing (CAD-CAM) systems.
