Description
Legierung für zahnärztliche Zwecke Gegenstand der Erfindung ist eine Legierung, die sich besonders gut für zahnärztliche Zwecke eignet.Alloy for Dental Use The invention provides a Alloy that is particularly suitable for dental purposes.
Die Legierung besteht aus Zinn. als Basismetall mit Zusätzen von Antimon und Wismut und weist einen besonders niedrigen Schmelzpunkt auf, eine mittlere Härte und eine große Korrosionsbeständigkeit gegen die im Mund wirksamen Agenzien. Die Legierung zeigt auch nach längerer Benutzung keine Verfärbung und ermöglicht eine scharfe Formfüllung beim Gießen; sie ist außerdem gut polierbar und weist eine gute Anpolierfähigkeit mit exaktem Randschluß auf. Beispielsweise kann man eine Legierung verwenden, die als Basismetall 82% Zinn enthält, dem io% Wismut und 8% Antimon zugesetzt sind. Eine derartige Zusammensetzung ist brauchbar, jedoch soll die Erfindung nicht auf diese ganz spezielle Konzentration beschränkt sein.The alloy is made of tin. as base metal with additions of antimony and bismuth and has a particularly low melting point, medium hardness and great resistance to corrosion by the agents acting in the mouth. the Alloy shows no discoloration even after prolonged use and enables one sharp mold filling when pouring; it is also easy to polish and has a good Abpolierbarkeit with exact edge fit. For example, you can use an alloy use, which contains 82% tin as base metal, to which io% bismuth and 8% antimony are added are. Such a composition is useful but is not intended to be part of the invention be limited to this very special concentration.
