Description

1Vletallegierung für zahnärztliche Zwecke. Silber-Zinn-Legierungen sind an sich bekannt. Man hat sie mit einem Silbergehalt von ro bis 2o Prozent zum Verzinnen verwendet. Auch, haben die Amalgame bei einem Silbergehalt von 50 Prozent etwa 40 Prozent Zinn..1Vletal alloy for dental purposes. Silver-tin alloys are known per se. They have been used for tinning with a silver content of ro to 20 percent. Also, with a silver content of 50 percent, the amalgams have about 40 percent tin.

Die Erfindung betrifft nun eine Silber-Zinn-Legierung mit goTeilen Silber und 1o Teilen Zinn. Versuche mit dieser Legierung haben das überraschende und nicht vorauszusehende Ergebnis gehabt, daß sie sich besonders für Gußfüllungen und Einlagen in der Zahnheilkunde gut eignet.The invention now relates to a silver-tin alloy with gold parts Silver and 10 parts pewter. Experiments with this alloy are surprising and unpredictable result that they are particularly suitable for cast fillings and insoles are well suited in dentistry.

Wenngleich sich eine Legierung mit go Teilen Silber und 1o Teilen Zinn am besten bewährt hat, so kann sich doch ihre Zusammensetzung ändern, etwa zwischen 5 und 2o Teilen Zinn bei einem entsprechenden Silbergehalt. Insbesondere eignet sich die neue Legierung für Kronen- und Brückenarbeiten, weil bei diesen keine elektrolytischen Korrosionserscheinungen auftreten. Die Zusammensetzung ist nämlich so gewählt, daß sie innerhalb des homogenen Gebietes liegt, also die Bildung lokaler galvanischer Elemente ausgeschlossen ist. Bei den bisher als Füllung verwendeten Silber-Zinn-Legierungen konnte letzteres eintreten. Hinzu kommt, daß die bisherigen Silber-Zinn-Legierungen infolge zu geringer Festigkeit für Brückenarbeiten ungeeignet sind.Albeit an alloy with good parts silver and 10 parts Tin has proven to be the best, but its composition can change, for example between 5 and 20 parts of tin with a corresponding silver content. In particular the new alloy is suitable for crown and bridge work, because with these no electrolytic corrosion phenomena occur. The composition is namely chosen so that it lies within the homogeneous area, i.e. the formation local galvanic elements is excluded. For those previously used as a filling The latter could occur in silver-tin alloys. In addition, the previous ones Silver-tin alloys unsuitable for bridge work due to insufficient strength are.
