Achieving reliable bonding between resin cements and high-strength ceramics, such as zirconia, is challenging due to the material's chemical inertness and absence of silica, which prevents traditional etching. This lack of etchability and inability to undergo silanization has led to ongoing debates among clinicians and researchers. Since zirconia restorations may occasionally fail to withstand dislodging forces, in current literature various alternative protocols have been suggested to improve bond strength between resin cements, tooth structures, and zirconia surfaces. For the long-term success and survival of of zirconia restorations, achieving sufficient bond strength is crucial to endure functional masticatory stresses. Consequently, the performance and bonding efficiency of these restorations are heavily dependent on the cementation procedure used. Despite extensive research, the literature on zirconia cementation presents conflicting results about the effectiveness of different luting agents, and no standardized protocol has been universally accepted. This review aims to categorize and evaluate the existing techniques designed to enhance the adhesion of zirconia to dental substrates. It also explores current trends in surface conditioning methods, seeking to identify approaches that offer consistent and reliable bonding outcomes. By analyzing these methods, this review aims to provide a clearer understanding of effective bonding strategies for zirconia restorations.
