Description

Verfahren zur Herstellung von Modellen für Zahnersatzteile. Die Erfindung betrifft ein Verfahren zur Herstellung von Modellen für Zahnersatzteile in Metallguß und ist gekennzeichnet durch die Verwendung des für diese Zwecke bekannten Alabastergips zu vier Teilen mit zwei Teilen von feingepulvertem Glas und einem Teil feingesiebten Seesandes. Diese Mischung gut verrührt und leicht erwärmt gibt mit Wasser verbunden einen rahmartigen Brei, der sich gut zum Ausgießen von Abdrücken eignet. Nach dem Erhärten der Gußmasse wird die Abdruckmasse wie üblich entfernt und das entstandene Modell getrocknet. Dieses ist geeignet für jede Gußarbeit, die auf demselben modelliert und gegossen werden kann.Process for the production of models for dental prostheses. The invention relates to a method for the production of models for dental prostheses in cast metal and is characterized by the use of the alabaster plaster known for this purpose to four parts with two parts of finely powdered glass and one part of finely sifted glass Sea sand. This mixture is stirred well and slightly warmed gives it combined with water a cream-like porridge that is well suited for pouring impressions. After this When the casting material hardens, the impression material is removed as usual and the resulting material is removed Model dried. This is suitable for any casting work modeling on the same and can be poured.

Der Arbeitsgang ist 'folgender Ein Abdruck, mit Gips oder plastischer Masse genommen, wird gesäubert, mit Wasserglas ausgestrichen und mit einem rahmartigen Brei, bestehend aus Wasser, vier Teilen Alabastergips, zwei Teilen feingepulvertem Glas und einem Teil Seesand, ausgegossen. Gips, Glas und Sand müssen vor dem Anrühren angewärmt werden und gut gemischt -sein. Ist die Abdruckmasse in üblicher Weise entfernt, wird das so gewonnene Modell nachgetrocknet und radiert. Nunmehr wird die Arbeit modelliert, mit Gußstiften versehen, das Ganze wird für die gewünschte Gußform beschnitten, mit einem Brei aus Wasser, zwei Teilen Alabastergips und zwei Teilen Seesand bestrichen und in die Form gestellt; diese wird dann mit dem Brei gefüllt und wie üblich zum Guß bereitet. Der Guß kann in 2o bis 30 Minuten erfolgen.The process is as follows: An impression, taken with plaster of paris or plastic mass, is cleaned, smeared with water glass and poured with a cream-like paste consisting of water, four parts of alabaster plaster, two parts of finely powdered glass and one part of sea sand. Plaster of paris, glass and sand must be warmed up and mixed well before being mixed. Once the impression material has been removed in the usual way, the model obtained in this way is dried and erased. Now the work is modeled, provided with casting pins, the whole thing is cut to the desired casting shape, coated with a paste of water, two parts of alabaster plaster and two parts of sea sand and placed in the mold; this is then filled with the paste and prepared for casting as usual. The casting can be done in 20 to 30 minutes.
