USE OF GOLD-PALLADIUM ALLOYS FOR DENTAL CASTINGS

摘要

: Gold-palladium alloys with a high gold content for dental applications should, for reasons of biocompatibility, not contain any toxically dubious components. For particularly corrosion-resistant and biocompatible Type-4 alloys, tin is needed as the only base-metal component in amounts between 0.7 and 5.8 wt-% if one remains within defined limits in the palladium-tin diagram. Such alloys contain, in addition to gold and tin, 6 to 25 wt-% palladium, 0 to 12 wt-% platinum and 0 to 2 wt-% iridium, rhodium and/or ruthenium.
