Bonding of resin cements to an aluminous ceramic: a new surface treatment.
OBJECTIVE
The purpose of the work reported here was to develop a surface treatment of an alumina-based ceramic (In Ceram) that would make reliable bonding to a resin-based luting agent possible.


METHODS
The surface treatment studied was the application of a suspension of a fine-grained, refractory powder, which after drying was sintered to the surface at 960 degrees C. The adherence potential of the surface was determined by measurement of bond energy.


RESULTS
It was found that the surface treatment, in conjunction with a heat-treated, silane coupling agent, resulted in mean bond energies of 47 (+/- 19), 56 (+/- 22), and 525 (+/- 116) J/m2 for the three resin cements studied.


CONCLUSIONS
It was concluded that the new surface treatment makes reliable bonding possible, which may allow new indications for this material.
