[Tensile strength of the bond to In-ceram after varying modes of surface conditioning].
The tensile bond strengths of six different resin-bonding-systems to the aluminium oxide ceramic In-Ceram were tested. The samples were stored in artificial saliva (37 degrees C) up to 150 days and thermocycled (5 degrees-55 degrees C, 18,750 cycles). After sandblasting or silicoating of In-Ceram the tensile bond strength of the modified Bis-GMA resin Panavia-Ex showed no significant changes within this observation period. Using the conventional Bis-GMA resin Microfill-pontic, silicoating In-Ceram with the Rocatec-system resulted in a better bond strength than the use of a silane. The used etching procedure with boiling 70% sulphuric acid was proven to be unsuitable for a long-term stable bond.
