[Pre-treatment of dental alloy for adhesive restorations. Part 3. Alkyl ammonium/Sn composite plating to various dental alloys].
The effect of alkyl ammonium salt/Sn composite plating on the adhesive characteristics of dental alloys was examined. The surface of dental alloys, on which such a composite plating was made, was analyzed by ESCA. The effect of the length of alkyl chain and its terminal atomic groups on the tensile adhesive strength to an adhesive resin was also examined. ESCA analysis revealed that both C and N atoms from the alkyl ammonium salts were certified on the surface of the dental alloys. Stable tensile adhesive strength, as high as 500 kg/cm2, was obtained when the number of C atoms of alkyl chain was 10 to 16. The alkyl ammonium salts containing such groups as hydroxyl, amino and vinyl at the terminal of the alkyl chain, were effective for increasing the tensile adhesive strength.
