Description

Ersatzkauwerkzeuge Die Erfindung bezieht sich auf Ersatzkauwerkzeuge (z. B. Prothesen, Klammern, Schienen) und besteht darin, daß diese Gegenstände im Wege des Formgusses aus korrosionsbeständigeniLegierungen hergestellt werden, die neben Kobalt io bis 40 '/" Chrom enthalten. Diese Legierungen-können außerdem als teilweisen Ersatz für Kobalt bis zu 40 0/, Nickel (vorzugsweise nur bis :2504) und bis 250/,) Eisen und ferner Wolfram, Molybdän, Tantal bis zu, je 50/0 enthalten. Kohlenstoff, Silicium, Mangan können in Mengen bis zu j e 10/, in der Legierung vorhanden sein.Replacement chewing tools The invention relates to replacement chewing tools (e.g. prostheses, brackets, splints) and consists in the fact that these objects in the Ways of molding are made from corrosion-resistant alloys that In addition to cobalt, they contain up to 40 '/ "of chromium. These alloys can also be used as partial replacement for cobalt up to 40 0 /, nickel (preferably only up to: 2504) and up to 250 /,) iron and also tungsten, molybdenum, tantalum up to 50/0 each. Carbon, silicon and manganese can be present in the alloy in amounts of up to 10 / to be available.

Ersatzkauwerkzeuge aus der folgenden Legierung haben sich in besonderem Maße bewährt: 57% Kobalt, 17,50/a Chrom, 2i% Nickel, g % Wolfram, i0/0 Eisen und o,5 °[o Kohlenstoff.Replacement chewing tools made from the following alloy have proven particularly useful Proven dimensions: 57% cobalt, 17.50 / a chromium, 2i% nickel, g% tungsten, 10/0 iron and 0.5 ° [o carbon.

Es hat sich gezeigt, daß die aus den vorgenannten Legierungen hergestellten Ersatzkauwerkzeuge zum mindesten in demselben Ausmaße gegenüber oxydierenden Einflüssen, :gegenüber dem Angriff von Mundsäften oder Arzneien, wie überhaupt gegen chemische Agenden beständig sind und keine Wirkung auf die Geschmacksnerven ausüben, wie Ersatzkauwerkzeuge, zu deren Herstellung die bisher üblichen metallischen Werkstoffe, nämlich Goldlegierungen, ferner Chrom-Nickel-und Chrom-Nickel-Eisen-Legierungen, verwendet wurden. Gegenüber den bisher für den angegebenen Zweck verwendeten Legierungen zeichnen sich aber die Legierungen, die gemäß Erfindung Verwendung finden sollen, dadurch aus, daß sie die Gießformen auch bei geringen Wandstärken und verwickelten Formen, wie sie gerade in der Zahntechnik vorkommen, aufs beste ausfüllen, so daß, auch die kleinsten Gußstücke (Zahnklammern usw.) ohne Schwierigkeiten mit großer Genauigkeit scharf abgegossen werden können. Ein weiterer Vorteil gegenüber den bisher gebräuchlichen Ersatzkauwerkzeugen liegt ferner in der höheren Elastizität der Gegenstände gemäß der Erfindung.It has been shown that those made from the aforementioned alloys Replacement chewing tools at least to the same extent against oxidizing influences, : against the attack of oral juices or medicines, as against chemical ones in general Agendas are persistent and have no effect on the taste buds, such as replacement chewing tools, for their production the previously common metallic materials, namely gold alloys, Chromium-nickel and chromium-nickel-iron alloys were also used. Opposite to however, the alloys previously used for the stated purpose stand out the alloys to be used according to the invention, characterized in that they use the casting molds even with thin walls and intricate shapes like them occur especially in dental technology, fill them out as best as possible, so that even the smallest Castings (brackets, etc.) sharp without difficulty with great accuracy can be poured off. Another advantage over the previously common ones Replacement chewing tools also lies in the higher elasticity of the objects the invention.

Das Gießen der Ersatzkauwerkzeuge kann nach den in der Zahntechnik üblichen Methoden, z. B. durch Schleudern in eine vorerhitzte Form, erfolgen.The casting of the replacement chewing tools can be done according to the dental technology usual methods, e.g. B. by spinning into a preheated mold.
