Abstract
Objective: To analyze surface treatment protocols for improved bond strength to zirconia ceramics among the various types of surface treatment available. Methods: This is an integrative literature review, with articles published between 2013 and 2023, available in English and in full text. The search was carried out in the Pubmed database, using the descriptors “zirconia", “surface treatment”, “bond strength", “resin cements” and “cementation”, combined by the Boolean operator “AND”. Results: 17 articles were selected after applying the inclusion and exclusion criteria. The treatments analyzed were classified as mechanical (particle blasting abrasion, Rocatec, Siljet, Cojet systems and lasers) and chemical (selective infiltration etching, hydrofluoric acid solutions and primers/silanes containing MDP). Blasting abrasion increased the free energy of the surface and improved adhesion, although it can cause embrittlement. Systems such as Rocatec, Siljet and Cojet promoted good micromechanical retention with silica. Lasers did not demonstrate significant improvement, and selective infiltration etching was effective without causing fractures. HF solutions and primers/silanes showed unsatisfactory performance. Final considerations: Although there is no universal protocol, specific techniques can improve long-term bond strength.
