Descrição
Resumo:This 2 case report describes the best way to establish a chemical bond between zirconia (Y-TZP) and a resin cement. Researchers have found that an ideal surface treatment for this ceramic, considered chemically inert, should be tribochemical sandblasting, followed by silane and a 10 MDP-based bonding agent. Materials and Methods: Two Y-TZP RBFDp bridges were prepared in patients who did not want to undergo conventional treatment. The bridges were cemented, following the recommended protocol. A two-year and half follow-up was done to see its evolution. Results: The combination of tribochemical sandblasting plus ceramic primers managed to provide reliable adhesion to this crystalline ceramic. No detachments were observed, nor any type of postoperative sensitivity. The patients did not experience any difficulties in any of their oral functions during these two years. Conclusions: It was found that it is possible to adhere chemically and reliably to the Y-TZP, even in extreme cases in which it is impossible to opt for traditional fixed prosthesis treatments.
