چکیده
|
Several surface treatments have been suggested to improve coating ceramics adherence to zirconia. however,which of these treatments results in larger bond resistance is yet to be determined. this work measured bond resistance between coating ceramics e.max ceram (ivoclair vivadente®,germany)(e),zirliner (ivoclair vivadente®,germany) and zirconia samples vipi block zirconn (vipi,brazil). specimens were divided into six groups (n=10) and submitted to different surface treatments. group1: smooth block + e; group 2: smooth block,zirliner + e; group 3: blasting with aluminum oxide 110um + e; group 4: blasting with aluminum oxide 110um,zirliner+ e; group 5: rough block + e; group 6: rough block,zirliner+ e. results showed that the surface treatment significantly influenced shear bond resistance (p < 0.001). zirliner application significantly reduced bond resistance between zirconia and coating ceramics where the s urface was not roughened nor submitted to blasting. zirliner did not reduce bond resistance of roughened surfaces. smooth,roughened and blasted surfaces without the application of zirliner showed no differences in bond resistance. hence,we conclude that the application of zirliner does not increase shear bond resistance.
