Description

Die Erfindung betrifft ein Verfahren zur Herstellung von künstlichen .Zähnen, Zahnfüllungenund Zahnbrücken aus Polymerisaten oder Mischpolymerisaten und besteht darin; daß man die gepulverten Kunstharze mit Kieselsäuregel in gallertartigem Zustande mischt. Hierdurch wird der Nachteil bekannter Verfahren vermieden, daß die üblichen mineralischen Füllstoffe im Gemisch mit Kunstharzpulver eine Neigung zum Entmischen zeigen.The invention relates to a method for the production of artificial teeth, tooth fillings and Dental bridges made of polymers or copolymers and consists of; that you can use the powdered synthetic resins mixed with silica gel in a gelatinous state. This makes the disadvantage more well known The method avoids that the usual mineral fillers mixed with synthetic resin powder have a tendency to separate demonstrate.

Nach dem Verfahren gemäß der Erfindung fällt man aus einer Lösung λόιι Natriumsulfat mit verdünnter Salzsäure in berechneter Menge Kieselsäuregel aus. Dieses Kieselsäuregel wird auf einem Tuch gründlich ausgewaschen und in noch feuchtem Zustand mit Kunstharzpulver gemischt. Nach dem Trocknen wird die Masse in bekannter Weise durch Zerreiben und Sieben in feines Pulver verwandelt. Die Färbung geschieht mit keramischen Farben.According to the process according to the invention, sodium sulfate is precipitated from a solution with dilute hydrochloric acid in a calculated amount of silica gel. This silica gel is placed on a cloth thoroughly Washed out and mixed with synthetic resin powder while still damp. After drying, the mass becomes known in Wise transformed into a fine powder by grinding and sieving. The coloring happens with ceramic colors.
