[Specific adhesive bonding of air-brushed alloy surfaces].
In vitro test have been conducted to examine if NiCr, CoCr and PdAg alloys air-brushed with aluminium oxide (grain size 250 microns) can be bonded in such a way that the bond resists humidity. After 150 days in water at 37 degrees C the high initial bond strength values of NiCr or CoCr alloys bonded with the modified bis-GMA adhesive Panavia remained unchanged. In the PdAg alloy specimens bonded with Panavia, the initial bond strength were approx. 60% lower than those of the NiCr and CoCr alloys, and were further reduced by approx. 33% after 150 days. As soon as after 15 minutes, the modified bis-GMA adhesive is cured to such an extent that functional loading of the bond interface is possible.
