Description

Die Erfindung betrifft gemäß Oberbegriff des Anspruch 1 ein Verfahren zur Herstellung eines Gerüstes für Inlays, Kronen und Brücken in der Zahntechnik, wie es aus der DE 196 11 734 A1 bekannt ist. Bei diesem Verfahren werden die Gerüste, z. B. aus Alumina, hergestellt, indem auf den Stumpf eines Arbeitsmodells eine Folie aufgezogen wird, die aufgezogene Folie mit einem Schlicker aus dem entsprechenden Material, z. B. Aluminia, versehen wird, dann die Folie vom Arbeitsmodell entnommen und mit dem darauf befindlichen Schlicker gebrannt wird. Beim Brennen der Keramikmasse verbrennt die Schrumpffolie und das Gerüst, z. B. in Form eines Käppchens, wird erhalten. Danach erfolgt üblicherweise die Infiltrierung des Käppchens mit einer Glasmasse. Auf dem so hergestellten Käppchen erfolgt anschließend der übliche Aufbau der Verblendkeramik.According to the preamble of claim 1, the invention relates to a method for Manufacture of a framework for inlays, crowns and bridges in dental technology like this is known from DE 196 11 734 A1. In this process, the scaffolding, e.g. B. made of alumina, by a film on the stump of a working model is drawn up, the drawn film with a slip from the corresponding Material, e.g. B. Aluminia, then the film from the working model removed and burned with the slip on it. When burning the ceramic mass burns the shrink film and the framework, e.g. B. in the form of a Little cap, will be preserved. This is usually followed by infiltration of the Cap with a glass mass. On the cap so produced then the usual structure of the veneering ceramic.

Der nach diesem Verfahren hergestellte Zahnersatz ist absolut metallfrei und somit biokompatibel und erreicht die Festigkeitswerte von Metallverbundkeramiken. Wegen der Einfachheit der Herstellung und der geringen Materialkosten kann für breite Bevölkerungsteile daher ein hochwertiger Zahnersatz zur Verfügung gestellt werden.The dentures produced by this process are absolutely metal-free and therefore biocompatible and achieves the strength values of metal composite ceramics. Because of The simplicity of manufacture and the low material costs can be wide Therefore, high quality dentures are made available to parts of the population.

Bei diesem bekannten Verfahren erfolgt bisher der Auftrag des Schlickers mit einem Pinsel. Dies hatte zur Folge, daß durch Abtropfen des Schlickers von der Folie Materialverluste entstehen. Bevor der Schlicker gebrannt wird, muß er ferner auf der Folie leicht antrocknen. Bisher wird dies durch eine entsprechende Verweilzeit an der Luft sichergestellt.In this known method, the slip has so far been applied with a Brush. As a result, the slip dripped off the film Material losses arise. Before the slip is burned, it must also be on the Dry the film slightly. So far, this has been achieved by a corresponding dwell time at the Air ensured.

Es ist daher Aufgabe der im Anspruch 1 angegebenen Erfindung, das bekannte Verfahren ohne Materialverlust zu beschleunigen.It is therefore an object of the invention specified in claim 1, the known Accelerate processes without loss of material.

Die Durchführung des Verfahrens wird durch die Vorrichtung nach Anspruch 7 sichergestellt.The method is carried out by the device according to claim 7 ensured.

Das erfindungsgemäße Verfahren und die benötigte Vorrichtung werden im folgenden anhand der Zeichnung näher erläutert.The inventive method and the required device are in following explained with reference to the drawing.

Der Motor 1 treibt eine Welle 2 an und ist bis auf eine Drehzahl von etwa einer Umdrehung pro Minute herab regulierbar. An der Spitze der Welle 2 ist der Stumpf 3, üblicherweise ein Gipsstumpf des Arbeitsmodells, mit einem Klebewachs 4 befestigt. Beim Hineinstecken des Stumpfes 3 in das Klebewachs 4 ist darauf zu achten, daß der Stumpf möglichst gut zentriert in Bezug auf die Drehachse der Welle angebracht ist, was das Auftragen des Schlickers erleichtert. Das Anbringen eines Stumpfes in dieser Art ist bereits in der DE 198 16 546 A1 vorgeschlagen. Diese Anmeldung lehrt jedoch nicht die erfindungsgemäße Trocknung durch einen Fön.The motor 1 drives a shaft 2 and can be regulated down to a speed of approximately one revolution per minute. The stump 3 , usually a plaster stump of the working model, is attached to the tip of the shaft 2 with an adhesive wax 4 . When inserting the stump 3 into the adhesive wax 4 , care must be taken that the stump is centered as well as possible with respect to the axis of rotation of the shaft, which facilitates the application of the slip. Attaching a stump in this way has already been proposed in DE 198 16 546 A1. However, this application does not teach drying according to the invention using a hair dryer.

Auf der Präparation des Stumpfes 3 ist eine Folie 6 aufgeschrumpft. Damit ein faltenfreies Aufschrumpfen erzielt wird, ist es zweckmäßig, die Folie aufzuschrumpfen, wie es in der DE 198 01 532 A1 vorgeschlagen wird.A film 6 is shrunk onto the preparation of the stump 3 . So that a wrinkle-free shrinking is achieved, it is expedient to shrink on the film, as is proposed in DE 198 01 532 A1.

Mit Hilfe des Werkzeugs 5, beispielsweise eines Pinsels, wird der Schlicker auf die Folie 6 aufgetragen. Von besonderem Vorteil ist es, wenn eine Auftragsvorrichtung benutzt wird, die in der DE 198 01 534 A1 vorgeschlagen wurde.Using the tool 5 , for example a brush, the slip is applied to the film 6 . It is particularly advantageous if an application device is used, which was proposed in DE 198 01 534 A1.

Während und/oder nach dem Auftragen des Schlickers wird der Schlicker mit einem Gas getrocknet, das über Umgebungstemperatur erwärmt ist. Hierzu wird zweckmäßigerweise ein Fön 7 benutzt, dessen Luftaustrittstemperatur regelbar ist. Während des Schlickerauftrags hat sich eine Lufttemperatur von 25°C bis maximal 40°C bewährt.During and / or after the application of the slip, the slip is dried with a gas which is heated to ambient temperature. For this purpose, a hair dryer 7 is expediently used, the air outlet temperature of which can be regulated. An air temperature of 25 ° C to a maximum of 40 ° C has proven itself during the slip application.

Das Anblasen des Schlickers mit erwärmter Luft beschleunigt den Trocknungsvorgang und ermöglicht eine gleichmäßige Trocknung der Schlickermasse, was sich positiv auf das Gefüge des gebrannten Keramikmaterials auswirkt.Blowing the slip with heated air accelerates the drying process and enables a uniform drying of the slip mass, which has a positive effect affects the structure of the fired ceramic material.

Nachdem der Schlicker angetrocknet ist, muß die Folie 6 vom Stumpf 3 entfernt werden. Hierzu wird die Föntemperatur auf 80-120°C gesteigert, was zum Schmelzen des Trennmittels führt, das sich zwischen der Folie 6 und der Präparation des Stumpfes 3 befindet. Ein leichtes Abziehen der Folie ist somit gewährleistet.After the slip has dried, the film 6 must be removed from the die 3 . For this purpose, the hair dryer temperature is increased to 80-120 ° C., which leads to the melting of the release agent which is located between the film 6 and the preparation of the die 3 . This ensures easy removal of the film.

Die Folie 6 mit dem darauf befindlichen Schlicker wird anschließend gebrannt, wobei das Plastikmaterial der Folie rückstandsfrei verbrennt. Nach der sogenannten Infiltrierung des gebrannten Käppchens und der üblichen Bearbeitung kann der Aufbau der Keramikmasse erfolgen.The film 6 with the slip thereon is then fired, the plastic material of the film burning without residue. After the so-called infiltration of the fired cap and the usual processing, the ceramic mass can be built up.

Aus vorstehenden Ausführungen ist auch ersichtlich, daß sich das erfindungsgemäße Verfahren ohne Schwierigkeit in das automatisierte Verfahren gemäß der DE 198 16 546 A1 integrieren läßt.From the above, it is also apparent that the invention Process without difficulty in the automated process according to the DE 198 16 546 A1 can be integrated.
