Description

Die Herstellung von Zahnprothesen aus Kunststoff erfolgt bisher derart, daß eine Mischung aus festem und flüssigem Kunststoff, Idl. h. eine bei normaler Temperatur plastisch knetbare Kunststoffmasse, in die geöffnete Form (Küvette) eingebracht und von Hand in die Teile der Form hineingedrückt wird; alsdann wird die Küvette geschlossen und unter einer Presse bis zum Küvettenschluß gepreßt; darauf wird die Küvette in einen Küvettenbügel gebracht und durch diesen gehalten; schließlich wird die so vorbereitete Küvette in einem Wasserbad bis auf etwa 100.0 C erhitzt um den Kunststoff in seimenf Endzustand zu bringen. To date, plastic dentures have been manufactured in such a way that that a mixture of solid and liquid plastic, Idl. H. one at normal Plastic material that can be kneaded at a plastic temperature, placed in the open mold (cuvette) and pressed into the parts of the mold by hand; then the cuvette closed and pressed under a press until the flask closes; then the Cuvette placed in a cuvette bracket and held by this; eventually will the cuvette prepared in this way is heated in a water bath up to about 100.0 C around the Bringing plastic to its final state.

Abgesehen davon,, daß die genaue Dosierung der in die Küvette einzubringenden Kunststoffmenge sehr schwierig ist, so daß sich einerseits entweder Hohlräume in der herzustellenden Prothese ergaben oder andererseits bei zu großer eingebrachter Kunststoffmenge umständliche Nacharbeiten erforderlich sind, um Bißerhöhungen auszugleichen, hat dieses Verfahren den Nachteil, daß es sehr umständlich und zeitraubend ist. Ein weiterer Nachteil besteht darin, daß die in die Küvette eingesetzten Zähne durch den von Hand ausgeübten Preßdruck nicht so fest mit der eigentlichen Prothese in Verbindung gebracht werden können, wie dies an sich erwünscht wäre; außerdem ist bei dem anzuwendenden starken Preßdruck ein Platzen der Porzellanfacetten ein häufig auftretender Übelstand. Apart from that, the exact dosage to be introduced into the cuvette Amount of plastic is very difficult, so that on the one hand there are either cavities in of the prosthesis to be produced or, on the other hand, if the prosthesis was too large Amount of plastic, cumbersome reworking is required to compensate for raised bites, this method has the disadvantage that it is very cumbersome and time-consuming. Another disadvantage is that the teeth inserted into the cuvette through the pressure exerted by hand is not so firmly attached to the actual prosthesis Can be connected as this would be desirable in itself; moreover is With the strong pressure to be applied, the porcelain facets burst frequently occurring evil.

Erfindungsgemäß sollen nun diese Nachteile dadurch vermieden werden, daß eine der herzustellenden Prothese entsprechend bemessene Menge Kunststoff in an sich bekannter Weise insbesondere mittels Hochfrequenzbeheizung od. dgl. auf Spritztemperatur erhitzt, unmittelbar anschließend daran in einen Spritzzylinder übergeführt und aus diesem mittels eines Spritzkolbens in die als geschlossene Spritzform ausgebildete Küvette eingespritzt wird. According to the invention, these disadvantages are now to be avoided by that one of the prosthesis to be produced correspondingly sized amount of plastic in in a manner known per se, in particular by means of high-frequency heating or the like Injection temperature heated, immediately afterwards in an injection cylinder transferred and from there by means of an injection plunger into the closed injection mold trained cuvette is injected.

Dieses an sich in der Kunststofftechnik für die Herstellung von anderen technischen Erzeugnissen bekannte Verfahren bringt auf dem Gebiet der Zahnprothesen insofern einen außerordentlich beachtlichen Fortschritt, als weder zu wenig noch zu viel Werkstoff in die Küvette hineingelangen kann, als fernerhin eine gleichmäßig hohe Verdichtung in der als geschlossene Spritzform ausgebildeten Küvette erfolgt, wobei infolge des hohen Spritzdruckes eine hohe Festigkeit der Prothese selbst und eine außerordentlich dauerhafte Verbindung der Prothese mit den eingesetzten Zähnen gewährleistet ist. This in itself in plastics technology for the manufacture of others Technological products known method brings in the field of dentures an extraordinarily considerable advance inasmuch as neither too little nor too much material can get into the cuvette than a uniform one high compression takes place in the cuvette designed as a closed injection mold, whereby due to the high injection pressure a high strength of the prosthesis itself and an extraordinarily permanent connection between the prosthesis and the inserted teeth is guaranteed.

Eine Einrichtung zur Ausführung des. neuen Verfahrens kann darin bestehen, daß die Einspritzöffnung der geschlossenen Küvette mit der Spritzdiisle eines Spritzzylinders in Verbindung gebracht wird, wobei zwischen dem Spritzkolben des Spritzzylinders und letzterem ein Raum vorgesehen ist, in welchem entweder der Kunststoff insbesondere mittels. eines Hochfrequenzfeldes od. dgl1. erhitzt werden kann oder in welchen der insbesondere mittels eines Hochfrequenzfeldes od. dgl. beheizte Kunststoff eingeschoben werden kann. Wie an sich bekannt, kann die Hochfrequenzbeheizung entsprechend der eingebrachten Kunststoffmerge automatisch regelbar bzw. abschaltbar sein, so daß der ganze Vorgang nach Einschalten der Hochfrequenzbeheizung automatisch gesteuert wird. A device for carrying out the new method can be incorporated therein exist that the injection opening of the closed cuvette with the Spritzdiisle an injection cylinder is brought into connection, with between the injection plunger of the injection cylinder and the latter, a space is provided in which either the Plastic in particular by means of. a high frequency field or the like1. be heated can or in which the od in particular by means of a high frequency field. heated plastic can be inserted. As is known per se, the high-frequency heating Can be automatically regulated or switched off according to the plastic merge introduced so that the whole process is automatic after switching on the high-frequency heating is controlled.

In der Zeichnung ist eine zur Ausführung des neuen Verfahrens dienende Einrichtung schematisch dargestellt. Auf die geschlossene Küvette 1 ist der Spritzzylinder 2 kraftschlüssig aufgesetzt. Oberhalb des. Spritzzylinders 2 ist ein durch die Elektroden 3 eines Hochfrequenzfeldes beheizter Raum vorgesehen, in welchem der Kunststoff 4 erhitzt wird. Nach der Erhitzung des Kunststoffes werden die Elektroden 3 ausgeschwenkt, worauf unter der Wirkung des Spritzkolbens 5 die in allen ihren Teilen gleichmäßig erhitzte Kunststoffmasse 4 in die Küvette 1 eingespritzt wird. In the drawing is one used to carry out the new method Device shown schematically. The injection cylinder is on the closed cuvette 1 2 positively attached. Above the injection cylinder 2 is a through the electrodes 3 of a high-frequency field heated room is provided in which the plastic 4 is heated. After the plastic has been heated, the electrodes 3 are swiveled out, whereupon under the action of the injection plunger 5 the uniform in all its parts heated plastic compound 4 is injected into the cuvette 1.
