Abstract

A multi-functional universal ceramic jig system is employed by a dental technician to press-fabricate ceramic dental prostheses. The system esp. has a number of tubes mounted on a single base plate. The tube mount is effected by screw-fit, push-fit or clamp etc. The base plate carries individual identifying marks alongside each muff.

Mulifunktions-Universal Presskeramik MuffelsystemMulti-functional universal press ceramic muffle system

Stand der Technik im zahntechnischen Presskeramikbereich ist es, dass das in Keramik zu pressende Objekt in Wachs modelliert wird.The state of the art in the field of dental pressed ceramics is that the object to be pressed in ceramic is modelled in wax.

Diese Wachsmodellation wird an einem Muffelformer in Zylinderform angebracht und mit feuerfester Einbettmasse eingebettet (ummantelt). Nach dem Abziehen des Muffelformers in Zylinderform entsteht in der feuerfesten Einbettmassenform ein parallelwandiger Hohlraum (Sackloch). Nach dem Aufheizen der feuerfesten Muffel verbrennt die Wachsmodel lation und es entsteht ein negativer Hohlraum. In den parallelwandigen Hohlraum (Sackloch) werden Keramimasse- Pellets gesintert, vorgesintert oder nur gepresste Keramik eingebracht. Darauf kommt ein Pressstempel aus feuerfester Einbettmasse, Keramikmasse, Metall, etc. Das Ganze wird wieder aufgeheizt bis die Presspellets zähflüssig werden. Dann wird mit Druck auf den Stempel die zähflüssige Keramik in die Hohlräume der Modellation gedrückt und verdichtet.This wax model is attached to a cylindrical muffle former and embedded (coated) with refractory investment material. After the cylindrical muffle former is removed, a parallel-walled cavity (blind hole) is created in the refractory investment material mold. After the refractory muffle is heated up, the wax model burns and a negative cavity is created. Ceramic mass pellets are sintered, pre-sintered or just pressed ceramics are introduced into the parallel-walled cavity (blind hole). A press stamp made of refractory investment material, ceramic mass, metal, etc. is placed on top of this. The whole thing is heated up again until the press pellets become viscous. Then, by applying pressure to the stamp, the viscous ceramic is pressed into the cavities of the model and compacted.

Nachteil bei bisher auf dem Markt befindlichen Systemen ist es, dass pro Muffel nur eine bestimmte Pelletfarbe gepresst werden kann. Hat man nun mehrere Farben, muß für jede Farbe eine extra Muffel eingebettet und gepresst werden.The disadvantage of the systems currently on the market is that only one specific pellet color can be pressed per muffle. If you have several colors, a separate muffle must be embedded and pressed for each color.

Sinn der Erfindung ist es durch mehrere Pressstempel in einer Muffel gleichzeitig verschiedene Keramikfarben in einem Arbeitsschritt zu pressen oder größere Keramikobjekte gleichzeitig mit mehreren Pressstempel zu pressen.The purpose of the invention is to press different ceramic colors in one work step using several press stamps in a muffle or to press larger ceramic objects simultaneously with several press stamps.

Das Multifunktions-Universal Presskermik Muffelsystem besteht aus einer Muffelgrundplatte, an der mehrere parallelwandige Muffelformer als Platzhalter für den späteren eigentlichen Pressstempel fest verbunden sind oder diese je nach Bedarf auf die Muffelgrundplatte durch Schrauben, Stecken, Klammern, etc. fixiert werden können. Die einzelnen Muffelform-Pressstempel-Platzhalter-Formen sind mit Buchstaben, Zahlen oder Zeichen versehen, die eine Farbzuordnung erleichtern. Diese Kennzeichnung kann auch auf der Muffelgrundplatte angebracht sein.The multifunctional universal press ceramic muffle system consists of a muffle base plate to which several parallel-walled muffle formers are firmly connected as placeholders for the later actual press stamp, or these can be fixed to the muffle base plate as required by screws, plugs, clamps, etc. The individual muffle mold press stamp placeholder shapes are provided with letters, numbers or symbols that make color assignment easier. This marking can also be applied to the muffle base plate.

Da beim Pressvorgang die Pressstempel alle gleichzeitig nach unten gedruckt werden, muß die Keramikpelletbestückung immer gleich sein, um eine unterschiedliche Pressstempel länge zu vermeiden. Bei einer unterschiedlichen Keramikpelletbestückung der Muffel muss dies durch unterschiedlich lange Pressstempel ausgeglichen werden oder durch Platzhaltepellets aus feuerfester Masse, Keramik, Metall, etc., die die gleiche Höhe aufweisen wie die genormten Keramikpellets.Since the pressing rams are all pressed downwards at the same time during the pressing process, the ceramic pellet load must always be the same in order to avoid different pressing ram lengths. If the muffle is loaded with different ceramic pellets, this must be compensated for by using different length pressing rams or by using placeholder pellets made of refractory material, ceramic, metal, etc. that are the same height as the standardized ceramic pellets.

Bei Pressmechanismen, die einen im Durchmesser zu kleinen Pressaufsatz haben, der nicht zwei oder mehrere Pressstempel gleichzeitig pressen kann, wird auf die Pressstempel eine im Durchmesser entsprechende Adapterplatte aus feuerfester Masse, Keramik, Metall, etc. aufgesetzt.In the case of press mechanisms that have a press attachment that is too small in diameter and cannot press two or more press stamps at the same time, an adapter plate made of refractory material, ceramic, metal, etc. with the appropriate diameter is placed on the press stamps.
