摘要: The goal of this research is to evaluate the effect sandblasting and silica coating on nano-roughness microtensile bond strength (MTBS) glass-infiltrated alumina bonded different resin cements. Six slabs In-Ceram Alumina (Vita) were randomly treated according following groups: (1) no treatment; (2) (125 μm Al2O3-particles); (3) tribochemical silica-coating (50 silanated particles). Nano-roughness (Ra) was assessed under an atomic force microscope (AFM). Such surface treatments also applied nine CAD/CAM blocks. Ceramic blocks duplicated in composite resin, samples conditioned surfaces. Each pre-treatment group divided into three subgroups depending cement system: Clearfil Primer plus Esthetic Cement (CEC, Kuraray); RelyX Unicem (RXU, 3M); Calibra Silane Resin (CAL, Dentsply). After 24 h, specimens cu...
