Abstract

The bronze pref. contains min. 81% copper, and is esp. an aluminium-bronze contg. 5-12% Al, pref. with the addn. of Fe and/or Ni, and/or Co, and/or Ag. The esp. pref. alloy contains 81% Cu, 11% Al, 4% Fe, and 4% Ni. The bronze can be used e.g. for the pegs on artificial teeth; crowns; straps; bridges; or for other parts of prostheses. The Al bronze is harmless to the human body, and possesses the required high strength. Dental prostheses are normally made of stainless steels, polymers, or Au- or Pt-alloys; but these materials are either unsightly or too expensive.The present invention provides an inexpensive material which resists corrosion, is easy to work, and has a pleasing appearance, i.e. a golden colour. After a suitable heat treatment, Al-bronze has a very high mechanical strength, with a high elastic limit, esp. when the alloy contains 81% Cu, 11% Al, and 4% each of Ni and Fe.

Description

In die Mundhöhle einzusetzender zahnärztlicher GegenstandDental item to be placed in the oral cavity

Die Erfindung betrifft einen in die Mundhöhle einzusetzenden zahnärztlichen Gegenstand aus metallischer Werkstoff oder mit Teilen aus metallischem Werkstoff für Zwecke der Zahntherapie, Kieferorthopädie, Zahnkosmetik u. dgl. The invention relates to a dental to be inserted into the oral cavity Object made of metallic material or with parts made of metallic material for purposes of dental therapy, orthodontics, dental cosmetics and the like.

Der metallische Werkstoff für solche Gegenstände, beispielsweise Gebißteile, Stiftzähne, Klammern, Spangen, Bügel, Kronen, Brücken, Prothesen usw., die zumindest Teile aus metallischem Werkstoff aufweisen, muB, bedingt durch seine Anordnung in der Mundhöhle, chemisch resistent sein, er muß vollkommen unschädlich für den Körper sein und er muß eine hohe Dehnfestigkeit aufweisen. Bisher wird nun dafür hauptsächlich rostfreier Stahl aber auch Kunststoff, Gold oder eine Platinlegierung verwendet, welche Werkstoffe entweder teuer oder unansehnlich, umständlich zu bearbeiten oder nicht immer verträglich oder auch zu wenig widerstandsfähig sind. The metallic material for such objects, for example Denture parts, pin teeth, brackets, braces, brackets, crowns, bridges, prostheses, etc., which have at least parts made of metallic material, must, due to its Arrangement in the oral cavity, chemically resistant, it must be completely harmless for the body and it must have a high tensile strength. So far is now mainly stainless steel but also plastic, gold or a platinum alloy used, which materials are either expensive or unsightly, awkward to work with or are not always tolerable or too little resistant.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Werkstoff für Gegenstände der eingangs geschilderten Art anzugeben, der die gewünschten Eigenschaften aufweist und darüber hinaus noch billig ist, leicht bearbeitet und gehandhabt werden kann sowie ein sehr gefälliges Aussehen besitzt. The invention is therefore based on the object of providing a material for Specify objects of the type described above, which have the desired properties and, moreover, is cheap, easy to edit and handle can as well as has a very pleasing appearance.

Die Erfindung löst diese Aufgabe dadurch, daß als Werkstoff Bronze vorzugsweise mit wenigstens 81 % Kupfer dient. Besonders eignet sich dabei eine Sonderbronze, nämlich Aluminiumbronze mit vorzugsweise 5 - 12% Aluminium als Werkstoff, wobei diese Aluminiumbronze Je nach gewünschten Eigenschaften als Zusätze Eisen, Nickel Kobalt oder Silber aufweisen kann, welche Zusätze jeweils alleine oder in Kombinationen miteinander verwendbar sind. The invention solves this problem in that bronze is used as the material preferably with at least 81% Copper is used. Particularly suitable A special bronze, namely aluminum bronze with preferably 5 - 12% aluminum as a material, this aluminum bronze depending on the desired properties as Additives iron, nickel, cobalt or silver can have, which additives respectively can be used alone or in combinations with one another.

Bronzen besitzen ausgezeichnete elastische Eigenschaften und insbesondere die Aluminiumbronzen zeigen hohe Festigkeitswerte und sind korrosionsbeständig, wobei ihnen auch eine gefällige goldene Farbe eigen ist. Legierungen mit 1d % Aluminium und mehr sind bei höherer Temperatur leicht verformbar und besitzen vor allem nach einer entsprechenden Wärmebehandlung eine außergewöhnlich hohe Festigkeit. Außerdem sind Aluminiumbronzen sehr widerstandsfähig gegen Stoßbelastungen und Ermüdungserscheinungen. Bronzes have excellent elastic properties and in particular the aluminum bronzes show high strength values and are corrosion-resistant, they also have a pleasing golden color. Alloys with 1d% aluminum and more are easily deformable at higher temperatures and, above all, have after an appropriate heat treatment an exceptionally high strength. aside from that aluminum bronzes are very resistant to shock loads and signs of fatigue.

Bronzen und insbesondere Aluminiumbronzen mit wenigstens 81 % Kupfer besitzen besonders günstige Dehnungs- und Elastizitätseigenschaften und z.B. eine Aluminiumbronze mit 81 % Kupfer, 11 % Aluminium, 4 , Eisen und 4 % Nickel ist ein hervorragender und dabei ein vergleichsweise billiger Ersatz für Zahngold.Bronzes and especially aluminum bronzes with at least 81% copper have particularly favorable elongation and elasticity properties and e.g. a Aluminum bronze with 81% copper, 11% aluminum, 4% iron and 4% nickel is a excellent and at the same time a comparatively cheap substitute for dental gold.

Die Eigenschaften der Bronzen und Aluminiumbronzen machen diese Legierungen überaus geeignet für die Verwendung als Dentallegierungen, d.h. für die Verwendung in der Zahnersatztechnik, der Kieferorthopädie, für die Zahnbehandlung und die Zahnkosmetik, wie z.B. für die Herstellung der Stifte von Stiftzähnen, von Kronen für natürliche Zähne, Klammern und Spangen, Teilbrücken, Bügel, Zahnregulierungen, künstlichen Zähnen usw. Alle metallischen Gegenstände, die für zahnärztliche Zwecke in die Mundhöhle eingesetzt werden, seien es die Gegenstände selbst oder nur Teile davon, können daher aus Bronze und Aluminiumbronze bestehen, welche Legierungen alle an sie gestellten Forderungen bestens erfüllen. The properties of bronzes and aluminum bronzes make these alloys extremely suitable for use as dental alloys, i.e. for use in denture technology, orthodontics, for dental treatment and dental cosmetics, e.g. for the production of pins for post teeth, for crowns for natural ones Teeth, brackets and braces, partial bridges, brackets, dental regulators, artificial ones Teeth etc. All metallic objects that are used for dental purposes in the oral cavity can be used, be it the objects themselves or only parts of them therefore consist of bronze and aluminum bronze, which alloys all put on them Meet requirements in the best possible way.
