The mechanism of bonding between resin cements and zirconia is still not well defined in the literature. Due to zirconia composition, there is a greater difficulty on these cements in establishing a chemical interaction, conferring a clinical dilemma in modern dentistry. Chemical adhesion, established by resin cements, is the most responsible for the bonding to zirconia when compared to mechanical treatments; which makes necessary the selection of the type of cement. Perform a literature review concerning the adhesion of resin cements to zirconia, emphasizing its advantages, composition, properties, and surface treatments. Elements that help on the adhesion and micromechanics retaining systems are essential to confer a long lasting and resistant bonding. Resin cements chemically activated may be more indicated for zirconia cementation than duo cements. Yet, self-adhesive resin cements promotes adequate adhesive resistance to zirconia. Concerning surface mechanical treatments, the aluminum oxide blaster indicates great efficiency on ceramics decontamination. However, to guarantee a greater bonding resistance, some coatings may be used previously to silanization, like the application of silica.
