THE BOND STRENGTH OF POLYMERS AND METAL-SURFACES USING THE SILICOATERTECHNIQUE

The silicoater technique, or silicoating, is a chemical bond system (m akes mechanical retentions unnecessary) which prevents the rising of a gap in the margin area between resin and metal. This procedure solves the problems of fracture and detachment of the veneer or its discolou rization. The purpose of this investigation was to find out the values of the bond strength achieved by using the silicoater technique on Ag -Pd alloy with smooth surface and with mechanical retentions on the su rface. Ninety specimens were divided into groups, subjected to water s torage and thermocycling. The values of the bond strength were investi gated in combination with this technique with Ag-Pd alloy and three ve neer materials. The silicoater technique gave the best results in comb ination with Dentacolor XS veneer material and mechanical retentions o n the surface of the dental alloy.
