CA 2296110

The invention relates to silver-palladium alloys for the manufacture of dental prostheses which can be faced with dental ceramic. Because of selected contents of the alloy elements indium, tin and zinc, these cause no discolorations when combined with low-melting dental ceramic with a coefficient of thermal expansion of approx. 16.5 µm/mK.

L'invention concerne des alliages argent-palladium utilisés pour produire une prothèse dentaire pouvant être revêtue de céramique dentaire. En raison de teneurs choisies en éléments d'alliage suivants: indium, étain, zinc, ces derniers n'induisent pas de changement de teinte lors de la combinaison avec de la céramique dentaire à faible point de fusion, à coefficient de dilatation thermique d'environ 16,5 mu m/mK.
