Abstract: Modern dentistry requires increasingly esthetic, tough ,and biocompatible restorative materials. The application of ceramic materials in fixed dental prostheses and restorations have become increasingly popular because they mimic natural tooth color in comparison to other restorative materials. Zirconium oxide (zirconia) demonstrates superior mechanical properties, chemical stability, and biocompatibility compared to other ceramic materials being applied in framework structures Etching with hydrofluoric acid and silanization are effective methods to bond silica-based ceramic materials). However, etching with hydrofluoric acid or silanization have no positive effect on the properties of zirconia because of their resistance to acids and absence of silicon oxide. Researchers have therefore proposed a number of surface conditioning methods to achieve reliable and durable bonding to zirconia over the past two decades. The representative materials and methods are airborne-particle abrasion with aluminum oxide particles (alumina blasting) airborne-particle abrasion with aluminum oxide modified with silica (silica-coating) followed by silanization, primers containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) luting agents containing MDP, selective infiltration-etching, and coating with nano-structured alumina The purpose of the current study was to evaluate the effect of mechanochemical surface preparation on the bond strength of a self-polymerizing acrylic resin bonded to zirconia.
