title: Tensile bond strength of resin luting cement to glass infiltrated porous aluminium oxide cores (In-Ceram).
abstract: The effect of various methods of surface treatment of glass infiltrated aluminium oxide (In-Ceram) on tensile bond strength was evaluated. Test specimens were formed as bars. After surface treatment of the flat ends, two bars were bonded together with either a dual curing resin (Twinlook) or a chemical curing resin with a phosphate monomer (Panavia Ex). After cementation the specimens were stored in humid conditions for 1 week and then thermocycled 1,000 times between 15 degrees C and 60 degrees C. The highest median tensile bond strengths were obtained with the Silicoater MD-method without the Opaquer and Twinlook as luting agent (23.9 MPa) or with sandblasting with 250 micrometers Al2O3 particles and Panavia Ex as luting agent (22.0 MPa).
