Description

Die Verwendung von Goldlegierungen für zahntechnische Zwecke Die vorliegende Erfindung bezieht sich nut die Verwendung von edelmetallhaltigen Legierungen für zahntechnische Zwecke, und zwar insbesondere zum Löten von Dentallegierungen, vornehmlich für solche Dentallegierungen, welche im wesentlichen aus Gold und Palladium und daneben aus Silber, Kupfer und Zink bestehen. Erfindungsgemäß enthalten die Legierungen 65 bis 750,0 Gold und Platin, wovon 2 bis 50;0 Platin sind, 1 bis 60b Silber, 8 bis I40/o Kupfer, 8 bis 14% Cadmium und o,I bis I % Zink. Außerdem können die zum Löten von Dentallegierungen verwendeten Legierungen noch Palladium enthalten mit der Maßgabe, daß der Gesamtgehalt an Platin und Palladium höchstens 8070 beträgt.The use of gold alloys for dental purposes The present The invention relates only to the use of precious metal-containing alloys for dental technology purposes, in particular for soldering dental alloys, primarily for such dental alloys, which essentially consist of gold and palladium and also consist of silver, copper and zinc. According to the invention, the alloys contain 65 to 750.0 gold and platinum, of which 2 to 50; 0 is platinum, 1 to 60b is silver, 8 up to 140 / o copper, 8 to 14% cadmium and 0.1 to 1% zinc. In addition, the Alloys used in soldering of dental alloys still contain palladium with with the proviso that the total content of platinum and palladium does not exceed 8070.

Dabei besitzen die erfindungsgemäß für zahntechnisch e Zwecke zu verwendenden Legierungen vor allem eine angenehme zahnbeinähnliche Goldfarbe, die sich nicht nur der Farbe der Zähne und des Zahnfleisches, sondern auch der Farbe von anderen Dentaliegierungen., z. B. der obengenannten Art, in vollkommener Weise anpassen. The invention for dental purposes have to The alloys used have a pleasant, dentin-like gold color that not only the color of the teeth and gums, but also the color from other dental alloys., e.g. B. of the type mentioned above, in a perfect manner adjust.

Außerdem enveisen sich die hier bteanspruchten Legierungen bei ihrer Verwendung für Dentalnvecke sehr beständig gegen Anlauf und Korrosion. was wiederum hauptsächlich für Dentallote von besonderem Wert ist. Die neuen Legierungen besitzen im allgemeinen Schmelzpunkte zwischen 700 bis 900°.In addition, the alloys stressed here are found in theirs Use for dental brackets very resistant to tarnishing and corrosion. what on the other hand is of particular value mainly for dental solders. Own the new alloys generally melting points between 700 and 900 °.

Beispielsweise kann man erfindungsgemäß Legierungen verwenden von folgender Zusammensetzung: 4Pd 2Pt 69Au 6Ag 10Cu 8Cd 1Zn oder 5Pd 5Pt 70Au 3Ag 8,5Cu 8Cd o,5Zn. For example, according to the invention, alloys can be used following composition: 4Pd 2Pt 69Au 6Ag 10Cu 8Cd 1Zn or 5Pd 5Pt 70Au 3Ag 8,5Cu 8Cd o, 5Zn.

Ähnliche Vorteile erhält man bei Verwendung von Legierungen, bei welchen an Stelle des in den Beispielen genannten Palladiums nur Platin vorhanden ist, und zwar in Mengen von 2 bis 50/0.Similar advantages are obtained when using alloys in which instead of the palladium mentioned in the examples, only platinum is present, and although in amounts of 2 to 50/0.
