Oral Session: Dental Materials 3: Ceramic-based Materials and Cements - 187. Clinical Studies, Surface, Interface, and Bonding: no. 1576OBJECTIVE: To investigate the effect of two cross-linking silanes blended with 3-acryloxypropyltrimethoxysilane on the shear bond strength between resin cement and silica-coated zirconia. MATERIALS AND METHODS: 90 specimens of zirconia (Nobel Biocare) were subjected to silica-coating by Rocatec Plus (3M ESPE, 110 μm) sand at an operation pressure of 280 kPa, for 30 s/cm2. 3M ESPE Sil-silane (3M ESPE) was used as a control. Primers of 1.0 vol% of 3-acryloxypropyltrimethoxysilane (ACPS), with 0.5 vol% cross-linking silanes bis-1,2-(triethoxysilyl) ethane (BTSE; Gelest) and bis[3-(trimethoxysilyl)propyl] amine (BTMA; ABCR) were prepared in a 95% ethanol and 5% deionised-water solvent mixture. The solutions were ...postprin
