Description

Künstlicher Zahn Zusatz zum Patent 666 923 Die Erfindung bezieht sich auf die Verensserung eines künstlichen Zahnes nach Patent 666 923, der aus einem Porzellankörper mit Verankerungsstiften besteht, die mit Hilfe von Formteilen unter Verwendung von Bidemittel in einem mit dem Zahnrücken zu vereinigenden Umschlußkörper eingelagert sind. Bei einem solchen Zahn bilden nach dem Hauptpatent die Verankerungsstifte zusammen mit den Formteilen einen vollen Metallblock, der nach Gestalt und Größe jeweils dem Hohlraum des Umschlußkörpers angepaßt und in diesen eingekittet ist. Hiermit wird erreicht, daß die an dem Zahnkörper befindlichen und an sich für die bloße Einldttung in den Zahnrücken ohne Depotbildung des Verkittungsmittels nicht geeigneten Stifte doch in den Zahnrücken bzw. in den damit zu verbindenden Umschlußkörper eingebettet werden können. Obwolhl solche Formteile zugleich mit den Porzellankörpern geliefert werden können, bereitet die Einpassung einige Schwierigkeiten, die erfindungsgemäß ausgeschaltet werden. Artificial Tooth Addendum to Patent 666 923 The invention relates is based on the verensserung of an artificial tooth according to patent 666 923, which from a porcelain body with anchoring pins is made with the help of molded parts using bidirectional in an enclosing body to be united with the back of the tooth are stored. According to the main patent, the anchoring pins form such a tooth together with the molded parts a full metal block, according to shape and size is adapted in each case to the cavity of the enclosing body and cemented into it. This ensures that those located on the tooth body and in itself for the mere loading into the back of the tooth without the formation of a deposit of the cementing agent is not possible suitable pins in the back of the tooth or in the surrounding body to be connected to it can be embedded. Although such molded parts at the same time as the porcelain bodies can be supplied, the fitting presents some difficulties, according to the invention turned off.

Die Verbesserung besteht darin, daß der aus dem Porzellankörper hervorstehende Teil der Verankerungsstifte und die Formteile zu einem geschlossenen, zweckmäßig rechtkantförmigen Hartmetallblock ausgebildet sind, der dann den Hohlraum des Umschlußkörpers ausfüllt und in diesen eingekhtet ist. The improvement is that the protruding from the porcelain body Part of the anchoring pins and the molded parts to form a closed, expedient Rectangular hard metal block are formed, which then the cavity of the surrounding body is filled out and locked into it.

Insbesondere für Kautschukarbeiten ist der Block weiterhin erfindungsgemäß mit Ausnehmungen versehen, die bei Verwendung des Porzellankörpers für Kronen- oder Brükkenarbeiten vor der Umkapselung durch den Umschlußkörper vermittels formentsprechender Körper mit oder ohne Verwendung von Bindemitteln ausfüllbar sind. Solche Körper, die in die Ausnehmungen des Blockes hineinpassen und den dadurch an sich für Kautschukarbeiten bestimmten Zahn f Kronen- oder Brückenarbeiten verwendbal, machen, können mitgeliefert werden, z.B. in der Gestalt von Paßstücken für schwablber schwanzförmige Ausnehmungen o.dgl. Bei Kautschukarbeiten wird der Metallblock natürlich ohne besonderen Umschlußkörper an die Gaumenplatte anvulkanisiert. In particular for rubber work, the block is still according to the invention provided with recesses that when using the porcelain body for crown or Bridge work prior to encapsulation by the enclosing body by means of corresponding shape Body with or without the use of Binders are fillable. Such bodies that fit into the recesses of the block and thereby Tooth intended for rubber work for crown or bridge work, can be supplied, e.g. in the form of adapters for schwablber tail-shaped recesses or the like. When working on rubber, the metal block becomes natural vulcanized to the palate plate without any special enclosing body.

In den Zeichnungen ist der Erfindungsgegenstand an Hand einzelner Beispiele näher erläutert. Es zeigen Abb. 1 die Rückansicht des Porzellankörpers mit rechtkantförmigem Hartmetallblock, Abb. 2 einen Schnitt längs der Linie a-a in Abb. I und Abb. 3 bis 6 weitere Ausbildungsformen, bei denen der Block mit Ausnehmungen versehen ist, in die formentsprechende Ergänzungskörper hineinpassen. In the drawings, the subject matter of the invention is based on individual Examples explained in more detail. Fig. 1 shows the rear view of the porcelain body with a rectangular hard metal block, Fig. 2 a section along the line a-a in Fig. I and Fig. 3 to 6 further training forms in which the block with recesses is provided, fit into the corresponding supplementary body.

Claims

In accordance with the main patent, 1 denotes the porcelain body, its incisal and root surface, as can be seen at I6 and I7 in Fig. 2 are protected by the cast metal tooth back 1o. In the porcelain body I again have the anchoring pins 2, but they are on the back of the porcelain body Form a single hard metal block 3 adjacent to this.

As can be seen from Fig. 2, a surrounding body is then above the block 3 11, which is cast in the metal tooth back 10.

The connection of the block 3 with the enclosing body 11 is only carried out by cementing. The production of the enclosing body can be done in such a way as les has been shown in the main patent, but its end faces can also stay open so that you can just get one. Use a section of a profile bar can that fits over the cross section of the block 3.

Is the tooth shown in Fig. 1 and 2 for rubber work is used, the block 3 is vulcanized into the rubber without the surrounding body 11.

In the other Fig. 3 to 6 recesses are provided in the block 3. These teeth are therefore initially applicable for rubber work, but that corresponding body are provided which fit into the cutouts are but they can also be used for crown and bridge work, as for the examples according to Fig. I and 2 is provided.

In Figures 3 and 6, the cutouts 20 are dovetailed, for example the cutout 20 in Fig. 3 engages up to about two, thirds of the block height, while it goes through the whole block in Fig. 6, it changes accordingly then of course the shape of the body 21, which has the cut-out block in both Complete cases to a full block, either with or without a binder.

Figs. 4 and 5 show recesses 22 on the end faces of the block 3, which in the case of Fig. 4 run vertically and in the case of Fig. 5 horizontally.

These recesses 22 can be filled by means of pieces of wire 23 take place. The part of the wire that extends over the side faces of the block can be filed down.

You can also make recesses of the type mentioned here yourself, if you only have teeth according to Fig. I and 2 available and not without special ones Want to vulcanize anchoring in a rubber plate.

The block can be transverse or along the central axis of the porcelain body depending on the width of the tooth. Such teeth can be used for metal and rubber work Find use.

PATENT CLAIMS: 1. Artificial tooth, consisting of a porcelain body with anchoring pins, which by means of molded parts and binders in one with the Tooth backs to be united enclosing bodies are embedded, according to patent 666 923, characterized ge = indicates that the protruding from the porcelain body part of the Anchoring pins (2) and the molded parts to form a closed, expediently rectangular Hard metal block (3) are formed, which the cavity of the surrounding body (II) is filled in and cemented into it.

2. Artificial tooth according to claim I, characterized in that the block (3) is provided with recesses (20), in particular for rubber work when using the porcelain body (I) for crown or bridge work prior to encapsulation by the enclosing body (II) by means of corresponding Body (2I or 23) can be filled with or without the use of binders.
