Description

Zahenersatzteil, wie Gaumenplatte u, dgl., auch Zubehör, wie Klammer, Zahnstift u. dgl., insbesondere Zahnkronen Zusatz zum Patent 511 637 Nach dem Patent 511 537 werden Zahnersatzteile, wie Gaumenplatten u. dgl., auch Zubehör, wie Klammer, Zahnstift u. dgl., aus Beryllium-Nickel-Legierungen, insbesondere mit 2 bis 8 % Beryllium, hergestellt. Es ist dor darauf hingewiesen, daß Prägestücke ebenso leicht wie aus Gold hergestellt werden können, die dann einer härtesteigernden Wärmebehandlung ausgesetzt werden müssen.Tooth replacement part, such as palatal plate and the like, also accessories, such as brackets, Dental post and the like, in particular dental crowns Addition to patent 511 637 According to the patent 511 537 are dental prosthesis parts, such as palatal plates and the like, also accessories, such as brackets, Dental post and the like, made of beryllium-nickel alloys, in particular with 2 to 8% Beryllium. It is pointed out that embossed pieces are just as easy how gold can be made, which then undergoes a hardness-increasing heat treatment must be exposed.

Ferner ist es bereits vorgeschlagen worden (ohne daß dies zum Stande der Technik gehört), daß diese Beryllium-Nickel-Legierungen bis zu 15% Chrom, Wolfram oder Molybdän einzeln oder gemischt enthalten können, oder daß der Nickelgehalt bis zu einem Drittel durch Eisen oder Kobalt einzeln oder zusammen ersetzt wird, ferner daß der Nickelgehalt bis zu 20% durch Kupfer, Gold oder Palladium ersetzt wird und schließlich, daß die Metalle der Chromgruppe ganz oder teilweise durch Vanadium oder Tantal einzeln oder zusammen ersetzt sind. Der Berylliumgehalt dieser Legierungen soll z. B. 0,5 bis 2,5 0/0 betragen. In dem Hauptpatent 5 I I 637 sowie in den obengenannten Vorschlägen ist vorzugsweise auf die Verwendung dieser Legierungen für Gaumenplatten, Klammenn u. dgl. hingewiesen, d. h. auf Teile, die ihre Form durch Biegen, Prägen o. dgl. erhalten, und es ist z. B. davon gesprochen, daß die Vergütung nach der Verarbeitung erfolgen soll. Unter Verarbeitung versteht man üblich eine Querschnittsverformung durch Walzen, Ziehen u. dgl.Furthermore, it has already been proposed (without actually being able to do so belongs to the technology) that these beryllium-nickel alloys contain up to 15% chromium, tungsten or molybdenum may contain individually or mixed, or that the nickel content up to a third is replaced by iron or cobalt individually or together, also that the nickel content is replaced by copper, gold or palladium up to 20% and finally that the metals of the chromium group are wholly or partially through Vanadium or tantalum are replaced individually or together. The beryllium content of this Alloys should z. B. 0.5 to 2.5 0/0. In the main patent 5 I I 637 and in the above proposals it is preferred to use these alloys indicated for palatal plates, clasps and the like, d. H. on parts that change their shape by bending, stamping o. The like. Obtained, and it is z. B. spoken of the fact that the Compensation should take place after processing. Processing is common a cross-sectional deformation caused by rolling, drawing and the like.

Es ist bekannt, daß man Chromnickelstähle sowohl in gewalztem bzw. gezogenem Zustande als auch gegossen für Zahnersatzzwecke verwenden kann. It is known that chromium-nickel steels are used in both rolled and can be used drawn as well as cast for dental prosthesis purposes.

Gegenstand der Erfindung sind Zahnersatzteile, wie Gatunenplatten u. dgl., auch Zubehör, wie Klammern, Zahnstifte u. dgl., insbesondere Zahnkronen, die durch Gießen aus Legierungen hergestellt sind, die 0,5 bis 2,5% Beryllium sowie eines oder mehrere der Metalle der Chromgruppe, und zwar Chrom in Mengen von 6 bis 20 0/0, Wolfram in Mengen von - 4 . bis 15 0/o, Molybdän in Mengen von 4 bis 1 5 °/0, Rest Nickel, enthalten. Der Nickelgehalt kann bis zu einem Drittel durch Eisen oder Kobalt oder auch bis zu 20 O/o der gesamten Legierungsbestandteile durch Kupfer, Gold oder Palladium ersetzt sein. Die Metalle der Chromgruppe können ganz oder teilweise durch Vanadium oder Tantal oder beide ersetzt sein. The invention relates to dental prostheses such as Gatunenplatten and the like, also accessories such as brackets, tooth pins and the like, in particular tooth crowns, which are made by casting from alloys containing 0.5 to 2.5% beryllium as well one or more of the metals of the chromium group, namely chromium in amounts from 6 to 20 0/0, tungsten in amounts of - 4. up to 15%, molybdenum in amounts from 4 to 15 ° / 0, remainder nickel. The nickel content can be up to a third due to iron or cobalt or up to 20% of the total alloy components by copper, Be replaced by gold or palladium. The metals of the chromium group can be wholly or partially be replaced by vanadium or tantalum or both.

Diese Legierungen sind einerseits gut gießbar, zum anderen sind auch bei ihnen die guten Festigkeitseigenschaften wirksam, zumal wenn die gegossenen Teile von hoher Temperatur abgeschreckt und dann in an sich bekannter Weise auf mittelhohe Temperaturen, die etwa zwischen 350 und 6000 liegen, angelassen werden. Über das Verhalten derartiger gegossener Legierungen für Zahnersatzteile war nichts vorauszusagen. Selbst @ wenn Zahnersatzteile aus den gleichen Le- @ gierungen in verarbeitetem Zustande bekanntgewesen wären, wäre nicht vorauszusehen gewesen, wie sich Gußstücke aus diesen mehrphasigen Legierungen verhalten würden. On the one hand, these alloys are easy to cast, on the other hand they are also with them the good strength properties are effective, especially when the cast Parts of high temperature quenched and then in per se known way be tempered to medium-high temperatures, which are between 350 and 6000. There was nothing about the behavior of such cast alloys for dental prostheses to predict. Even if dental prostheses are made from the same alloys in had been known in the processed state, it would not have been possible to foresee how castings made from these multiphase alloys would behave.

Gegenüber Zahnersatzteilen aus binären Beryllium-Nickel-Legierungen weisen die erfindungsgemäß aus Mehrstofflegierungen bestehenden Zahnersatzteile noch den Vorteil auf, daß sie auch bei besonders empfindlichen Patienten nicht zu Reizungen der Schleimhaut Anlaß geben. Compared to tooth replacement parts made of binary beryllium-nickel alloys show the dental prosthesis made of multi-component alloys according to the invention nor the advantage that it does not apply to particularly sensitive patients Give cause for irritation of the mucous membrane.
