Description

Verfahren zur Herstellung von Zahnprothesen in einem Stück aus Porzellan Das Herstellen von Reinporzellanbrücken war bisher eine schwierige und kostspielige Arbeit, ohne daß der gewünschte Erfolg; die Haltbarkeit oder das Passen, erzielt wurde. Es war nötig, erst die Grundpfeiler, d. h. die Jacketkronen, dann die Zwischenteile anzufertigen, bevor die Brücke endgültig zuzusammengebrannt werden konnte. Bei dem Zusammenbrennen stellen sich große Schwierigkeiten ein, da der Werkstoff beim Brennen durch Schrumpfen Veränderungen unterliegt, wodurch in dem Material Spannungen entstehen, die die Haltbarkeit und das Passen der Brücke in Frage stellen. Die Verbindungsstellen zwischen jacketkronen und Zwischengliedern sind die gefährdeten Bruchstellen, da das sich hier spannende Material geringe Festigkeit aufweist und dadurch das Verwenden der Reinporzellanbrücke kaum möglich ist, trotzdem dies auf dem Gebiet der Hygiene und zum Vermeiden der Zahnfleischreizung das Besterreichbare ist. Brücken mit eingebranntem Platingerippe weisen bei der Herstellung dieselben Schwierigkeiten durch das Schrumpfen beim Brennen auf. Diese Brücken bestehen auch aus mehreren zusammengebrannten Teilen oder aus verschiedenen aufeinandergebrannten Schichten. Hierbei entstehen Spannungen zwischen den. verschiedenen Porzellanschichten. Diese Mängel werden durch den Erfindungsgegenstand beseitigt, indem Zahnersatzstücke, Porzellan-Brücken, Zahnfleischblöcke, Jacketkronen aus einem massiven Stück hergestellt werden.Process for the manufacture of dentures in one piece from porcelain The manufacture of all-porcelain bridges has been difficult and costly so far Work without the desired success; durability or fit became. It was necessary to first lay the foundations, i.e. H. the jacket crowns, then the intermediate parts to be made before the bridge could finally be burned down. In which There are great difficulties in burning together because the material is burning is subject to changes due to shrinkage, which creates stresses in the material, that question the durability and fit of the bridge. The connection points between the jacket crowns and the pontics are the vulnerable break points the exciting material here has low strength and therefore the use the pure porcelain bridge is hardly possible, despite this in the area of hygiene and to avoid gum irritation is the most achievable. Bridges with branded Platinum ribs have the same difficulties in production due to shrinkage when burning on. These bridges also consist of several pieces burned together or from different layers fired on top of one another. This creates tension between. different porcelain layers. These deficiencies are made by the subject matter of the invention eliminated by adding dentures, porcelain bridges, gum blocks, jacket crowns can be made from one solid piece.

Das Wesen der Erfindung liegt darin, daß als porzellanartige Masse amorphes Aluminiumoxyd bis vor den angesinterten oder bis zum leicht angesinterten Zustand erhitzt wird, dann in diesem Zustand unter erhöhter Hitze und hohem Druck zu Formlingen in einem Stück gepreßt wird. Danach werden die Formlinge zum Fertigprodukt gebrannt; ein Nachschrumpfen findet nicht statt. Die Farbe kann nach Belieben abgestuft werden. Das Verfahren hat mit dem Pressen der in Hitze plastisch gewordenen Porzellanmassen nichts gemein. Die bisherigen Zahnporzellane weisen eine geringe Biegefestigkeit auf, deshalb ist die Herstellung von Reinporzellanbrücken zwecklos, da sie dem Kaudruck nicht standhalten. Dagegen ist die Biegefestigkeit des gebrannten amorphen Aluminiumoxyds bedeutend größer. Brücken, Zahnersatzteile usw. aus amorphem Aluminiumoxyd hergestellt, können nachgebrannt werden, ahne daß sie ihre Form verlieren, da sie einen hohen Erweichungspunkt aufweisen. Die Dichte der nach dem neuen Verfahren; aus amorphem Aluminiumoxyd hergestellten Körper ist einwandfrei, so daß die Körper nach Korrekturschliffen nur poliert zu werden brauchen. Das neue Verfahren hat mit dem Verfahren, bei welchem Brücken, Zahnersatzteile aus kristallisiertem Aluminiumoxyd unter Zusatz von Säure nach den üblichen keramische Formungsmethoden hergestellt....w@erden, nichts gemein, da bei diesem Verfahren .die-Schrumpfung erst beim Brennen nach-. m- Färrr}c.zi;, eintritt. , `°=-@The essence of the invention is that as a porcelain-like mass amorphous aluminum oxide up to before the partially sintered or up to the slightly partially sintered State is heated, then in this state under increased heat and high pressure is pressed into moldings in one piece. Then the moldings become the finished product burned; post-shrinking does not take place. The color can be graded at will will. The process involves pressing the porcelain masses that have become plastic in the heat nothing in common. The previous dental porcelains have a low flexural strength on, therefore the production of pure porcelain bridges is pointless, since they the chewing pressure not withstand. On the other hand, the flexural strength of the burned amorphous aluminum oxide is significantly larger. Bridges, dental prostheses, etc. made of amorphous aluminum oxide, can be burned afterwards, knowing that they will lose their shape, since they have a high Have softening point. The density of the new method; made of amorphous Aluminum oxide made body is flawless, so the body after corrective grinding just need to be polished. The new method has to do with the method in which Bridges, dental prostheses made of crystallized aluminum oxide with additives from Acid produced according to the usual ceramic molding methods .... w @ erden, nothing in common, because with this process .the shrinkage only after firing. m- Färrr} c.zi ;, entry. , `° = - @
