Abstract

The new dental alloy of high gold content which is particularly suited for facing with ceramic consists of from 91 to 99.4 % of gold, from 0.5 to 3 % of titanium and/or tantalum, from 0 to 5 % of silver and from 0 to 1 % of at least one of iridium, rhodium, ruthenium, platinum, palladium, osmium, tungsten, iron, molybdenum, niobium and rhenium, the percentages indicated being by weight.
This dental alloy is extremely biologically compatible and can be used in the conventional technique and in the burning-on technique as well so that it may be employed as a universal gold alloy which fulfils the standards ISO 1562 and ISO 9693 and, respectively, DIN 13927.
