Bond Strength of Milled and Printed Zirconia to 10-Methacryloyloxydecyl Dihydrogen Phosphate (10-MDP) Resin Cement as a Function of Ceramic Conditioning, Disinfection and Ageing

This study aimed to assess the suitability of printed zirconia (ZrO(2)) for adhesive cementation compared to milled ZrO(2). Surface conditioning protocols and disinfection effects on bond strength were also investigated. ZrO(2) discs (n = 14/group) underwent either alumina (Al(2)O(3)) airborne particle abrasion (APA; 50 µm, 0.10 MPa) or tribochemical silicatisation (TSC; 110 µm Al(2)O(3), 0.28 MPa and 110 µm silica-modified Al(2)O(3), 0.28 MPa), followed by disinfection (1 min immersion in …
