Description

Verfahren zur Herstellung einer Brennunterlage für Porzellanmantelkronen Die Erfindung betrifft ein Verfahren zur Herstellung einer Brennunterlage für Porzellanmantelkronen, und besteht darin, daß ein Positivabdruck des zu bekronenden Zahnes aus einer Porzellan- oder Quarzmasse unter Zusatz von Gips und Aluminiumacetat hergestellt wird, der nach Trocknen und Glühen durch Bestreichen mit einer Platin-Ammonium-Chlorid-Lösung einen dünnen, metallischen Überzug zum Aufbrennen der Mantelkrone erhält.Process for the production of a firing base for porcelain mantle crowns The invention relates to a method for producing a firing base for porcelain jacket crowns, and consists in making a positive impression of the tooth to be crowned from a porcelain or quartz mass is produced with the addition of gypsum and aluminum acetate, the after drying and glowing by brushing with a platinum-ammonium-chloride solution receives a thin, metallic coating for burning on the mantle crown.

Die bisher übliche Art, eine Brennunterlage für eine Porzellanmantelkrone dadurch herzustellen, daß man ein entsprechend zugeschnittenes Stück Platinfolie von 0,00a5 mm Stärke um das Zahnstumpfmodell legt, mittels eines Achat- oder Orangeholzstäbchens fest andrückt, die beiden Enden verfalzt oder mit einem hochschmelzenden Platinlot in der Sauerstoffflamme verlötet, stellt an den Ausführenden große Anforderungen an Geschicklichkeit und Sorgfalt, da durch Formveränderung beim Abheben vom Modell oder während des Brennens ein guter Sitz der fertig gebrannten Krone nicht immer gegeben ist.The usual way to date, a firing base for a porcelain mantle crown by making an appropriately cut piece of platinum foil 0.00a5 mm thick around the tooth stump model using an agate or orange wood stick press firmly, the two ends crimped or with a high-melting platinum solder Soldered in an oxygen flame places great demands on the person performing the work dexterity and care, due to the change in shape when lifting off the model or the finished crown does not always fit properly during firing given is.

Bei dem Verfahren nach der Erfindung werden die obengenännten Mängel dadurch vermieden, daß man von dem Zahnstumpf ein Modell von einer hochschmelzenden Porzellan- oder Quarzmasse herstellt. Dieser positive Abdruck des zu bekronenden Zahnes wird mit einer Platinemulsion bestrichen, welche nach dem Glühen einen festhaftenden, polierfähigen Platinüberzug ergibt, auf welchem das Porzellanmehl zum Brennen der Krone aufgetragen wird.In the method according to the invention, the above-mentioned shortcomings become apparent avoided by having a model of a high-melting point of the tooth stump Manufactures porcelain or quartz mass. This positive impression of the one to be crowned The tooth is coated with a platinum emulsion, which after annealing creates a firmly adhering, polishable platinum coating results, on which the porcelain powder for firing the Crown is applied.

Man kann sich beispielsweise eine Brennunterlage dadurch herstellen, daß man eine hochschmelzende Porzellan- oder Quarzmasse, der als Befestigungsmittel bestimmte Mengen Gips und Aluminiumacetat beigemengt sind, mit Wasser zu einem Brei anrührt und den Abdruck des zu behandelnden Zahnes damit ausgießt. Nach dem Trocknen und Glühen bis zu z4oo° C erhält dieser positive Abdruck eine sehr große Festigkeit, welcher, mit einer Platin-Ammonium-Chlorid-Lösung bestrichen durch Glühen einen metallischen, polierfähigen Platinüberzug erhält. Das Auftragen der Porzellanmasse und Brennen erfolgt nach dem bekannten Verfahren. Die fertig gebrannte Krone läßt sich leicht vom Modell abnehmen, so daß dasselbe zu weiteren Bränden Verwendung finden kann.For example, you can create a firing base by that you have a high-melting porcelain or quartz mass, which is used as a fastening means certain amounts of plaster of paris and aluminum acetate are mixed in with water to form a pulp touches and pours the impression of the tooth to be treated with it. After drying and annealing up to z400 ° C, this positive impression is very strong, which, smeared with a platinum-ammonium-chloride solution by annealing a metallic, polishable platinum coating. The application of the porcelain mass and firing is carried out according to the known method. The finished crown leaves can easily be removed from the model, so that the same can be used for further fires Can be found.
