Description

Verfahren zur Herstellung gegossener Goldzähne und Zahnersatzteile. Beim Gießen von Goldzähnen oder Ersatzteilen -wendet man auch schon Hohlguß an. Dazu benutzt man einen unveränderlichen Kern, der von vornherein kleiner als der Formraum hergestellt wird und in ihr zentriert werden muß, was sehr umständlich ist. Gegenstand der vorliegenden Erfindung ist ein Verfahren, welches sich durch die Benutzung eines Modellierkörpers aus: einer Mischung 'von Gips und Holzkohle kennzeichnet. Beim Ausbrennen wird derselbe nicht wie Wachs entfernt; sondern schrumpft nur zusammen und bildet dann gleich den Kern für den Hohlguß.Process for the production of cast gold teeth and dental prostheses. When casting gold teeth or replacement parts, hollow casting is also used. To do this, one uses an unchangeable core that is smaller than that from the start Mold space is produced and must be centered in it, which is very cumbersome is. The present invention is a method which is through the use of a modeling body made from: a mixture of plaster of paris and charcoal indicates. Burning out does not remove the same as wax; but is shrinking only together and then immediately forms the core for the hollow casting.

Eine beispielsweise Ausführungform des Verfahrens ist, daß man Gips und pulverisierte Holzkohle zu gleichen Teilen zur Modelliermasse mischt. Das Modellieren und d@arauffolgende Eingipsen geschieht in bekannter Weise. Das Gipsstück glüht man aus, dabei verbrennt die Hohlzkohle, der Körper schrumpft um den Volumenverlust zusammen und ist nun kleiner als der Hohlraum. Er bildet nun den Kern für den Hohlguß, um den sich beim Gießen das Metall verteilt.An example embodiment of the method is that plaster of paris is used and mix equal parts powdered charcoal with the modeling clay. The modeling and the following plastering is done in a known manner. The piece of plaster glows one off, in the process the char burns, the body shrinks by the loss of volume together and is now smaller than the cavity. It now forms the core for the hollow casting, around which the metal is distributed during casting.
