Description

Verankerungselemente für künstliche Zähne Für die Verankerung von künstlichen Zähnen, insbesondere aus Porzellan, in Kautschuk- oder Kunststoffplatten von Prothesen werden Stifte verwendet, die im allgemeinen in in die Zähne eingebrannte Hülsen eingelötet sind. Für die Herstellung dieser Verankerungselemente für künstliche Zähne, insbesondere der Einbrennhülsen, sind bisher im allgemeinen Gold-Palladium-Legierungen henutzt worden, die verhältnismäßig hohe Goldgehalte aufweisen. Man hat auch schon Palladium oder hochpalladiumhaltige Legierungen mit Gold oder Silber für derartige Zwecke verwendet, wobei allerdings in vielen Fällen beim Einbrennen die Gefahr einer Verfärbung des die Hülse umgebenden Zahnteiles auftritt.Anchoring elements for artificial teeth For anchoring artificial Teeth, in particular made of porcelain, in rubber or plastic plates for prostheses Pins are used, generally in sleeves burnt into the teeth are soldered. For the manufacture of these anchoring elements for artificial Teeth, especially those of the burn-in sleeves, have hitherto generally been gold-palladium alloys have been used, which have a relatively high gold content. One already has Palladium or high-palladium alloys with gold or silver for such Purposes used, although in many cases there is a risk of burn-in Discoloration of the tooth part surrounding the sleeve occurs.

Es sind auch schon derartige Verankerungselemente mit mindestens SoO/o Palladium und Silber oder Gold sowie mit Bor bekannt. There are already such anchoring elements with at least SoO / o palladium and silver or gold as well as boron are known.

Diese Verankerungselemente für künstliche Zähne, wie Zahnstifte und Einbrennhülsen, mit mindestens 80§/o Palladium und Silber oder Gold sowie mit Bor sind erfindungsgemäß durch 0,OI bis I,50/o, vorzugsweise 0,3 bis 0,70/01, Bor und 0,05 bis 0,2 °/o Iridium gekennzeichnet. These anchoring elements for artificial teeth, such as dental posts and Burn-in sleeves with at least 80% palladium and silver or gold and with boron are according to the invention by 0.1 to 1.50 / o, preferably 0.3 to 0.70 / 01, boron and 0.05 to 0.2% iridium.

Derartige Legierungen sind trotz ihrer hohen Härte und Festigkeit gerade für Hülsen, aber auch für Stifte, hervorragend verarbeitbar und genügen allen Anforderungen, die an Stifte oder Hülsen zur Befestigung künstlicher Zähne gestellt werden müssen. Such alloys are despite their high hardness and strength Especially for sleeves, but also for pens, extremely easy to process and suffice for everyone Requirements placed on pins or sleeves for fastening artificial teeth Need to become.

Durch den geringen Zusatz von Iridium in Mengen zwischen 0,05 und 0,2 0/o bewirkt man eine gewisse Kornverfeinerung der Legierungen. Die Kornverfeinerung macht sich bei der Verarbeitung sehr vorteilhaft bemerkbar. Due to the small addition of iridium in amounts between 0.05 and 0.2% a certain grain refinement of the alloys is achieved. The grain refinement is very beneficial during processing.

Eine Verfärbung der Zähne beim Einbrennen der Verankerungselemente tritt nicht auf. Die aus den Legierungen nach der Erfindung hergestellten Formkörper zeigen nach dem Einbrennen eine ausgezeichnete Haftfestigkeit im Zahn und gewährleisten andererseits eine feste Verbindung mit den aus gleichen oder ähnlichen Materialien bestehenden Zahnstiften. Es kann gegebenenfalls zweckmäßig sein, die fertigen Stifte oder Hülsen selbst oder die zu ihrer Herstellung benutzten Bänder oder Drähte vor ihrer Verwendung bzw. im Laufe des Verarbeitungsvorganges einer Glühbehandlung im Hochvakuum bei erhöhten Temperaturen, vorzugsweise bei solchen zwischen 8oo und 11000 C, zu unterziehen. Discoloration of the teeth when the anchoring elements are burned in does not occur. The moldings produced from the alloys according to the invention show and guarantee excellent adhesion in the tooth after baking on the other hand, a firm connection with those made of the same or similar materials existing dental posts. It may be useful to use the finished pens or sleeves themselves or the tapes or wires used to make them their use or in the course of the processing process an annealing treatment in High vacuum at elevated temperatures, preferably between 800 and 11000 C, to be subjected.
