| 520 | _aDevelopment of restorative materials that combine the advantages of ceramics and composite resins would enhance the properties and longevity of indirect esthetic restorations.Recently, novel CAD/CAM restorative materials for indirect restorations have been developed, based on polymer-infiltrated ceramic network materials (PICN).This study was designed to evaluate the effect of two surface treatments on the fracture resistance, micro-shear bond strengths and the surface morphological features of two indirect esthetic restorative materials to resin cements.Two commercially available ceramic blocks were used in this study; lithium disilicate blocks (IPS e.max) and hybrid ceramic blocks (VITA ENAMIC)For fracture resistance measurement; 20 ceramic inlays were fabricated using CEREC 3 InLab MC XL,and divided into two main groups according to type of the material; lithium disilicate glass ceramic inlays (IPS e.max) and hybrid ceramic (VITA ENAMIC). Each group was further subdivided into two subgroups according to surface treatment; hydrofluoric acid etch and aluminum oxide sandblasting. The inlays were silanized and cemented to epoxy resin dies using adhesive resin cement; Rely X unicem. After that, the inlays were subjected to static loading till fracture using universal testing machine with a load cell of 5 KN.The load was applied occlusally at the centre pit area and directed parallel to the long axes of the epoxy dies. Load was increased gradually and applied at rate of 0.5 mm/min till failure occurs.The load at failure was recorded as fracture load (Newton) | ||
