摘要: The bonding strength between resin cement and posts is important for post core restorations. An method of improving the use various surface pretreatments post. In this study, surfaces zirconia (fiber) were treated by mechanical and/or chemical methods such as sandblasting silanization. was measured a push-out after thermocycling based on adhesion to Panavia F 2.0 cement. fiber exhibited different strengths silanization because structures. showed high up 17.1 MPa combined treatment rough covalent bonds at interface. This effect also enhanced using 1,2-bis(trimethoxysilyl)ethane formation flexible layer contrast, 13.9 obtained silane agents resulted in damage post, observed scanning electron microscopy. results indicated that improvement could be controlled treatments. Enhanced depended roughness. A with potentially used restoration teeth future.
