Abstract
Description
Die Erfindung betrifft ein Druckformgerät zur Herstellung einer Dentalschiene, aufweisend eine Druckkammer mit einem ersten Kammerteil und einem zum Schließen der Druckkammer damit verbindbaren zweiten Kammerteil, wobei an dem ersten Kammerteil eine erste Halteeinheit zum Halten eines Kiefermodells angeordnet ist und das zweite Kammerteil eine Fixiereinrichtung zur Fixierung eines Tiefziehmaterials umfasst, wobei das zweite Kammerteil mit einer Druckbeaufschlagungseinrichtung verbindbar ist, über die das Tiefziehmaterial bei geschlossener Druckkammer derart mit Druck beaufschlagbar ist, dass das Tiefziehmaterial über das Kiefermodell tiefgezogen werden kann.The invention relates to a printing forme device for producing a dental splint, comprising a pressure chamber with a first chamber part and a second chamber part connectable to close the pressure chamber, wherein a first holding unit for holding a jaw model is arranged on the first chamber part and the second chamber part is a fixing device for fixing a Tiefziehmaterials, wherein the second chamber part is connectable to a pressurizing device, via which the thermoforming material in the closed pressure chamber can be acted upon with pressure such that the thermoforming material can be thermoformed on the jaw model.
Ein entsprechendes Druckformgerät ist beispielsweise aus
Mit der Erfindung wird ein neuartiges Druckformgerät zum Herstellen einer Dentalschiene vorgeschlagen, mit dem hochwertige Dentalschienen mit okklusalen Einprägungen des Gegenkiefers auf einfache Art und Weise herstellbar sind.The invention proposes a novel pressure molding apparatus for producing a dental rail, with which high-quality dental splints with occlusal impressions of the opposing jaw can be produced in a simple manner.
Diese Aufgabe wird ausgehend von einem Druckformgerät der eingangs genannten Art dadurch gelöst, dass an dem zweiten Kammerteil eine zweite Halteeinheit zum Halten eines Gegenkiefermodells angeordnet ist, wobei die erste und die zweite Halteeinheit bei geschlossener Druckkammer derart zueinander angeordnet sind, dass das Gegenkiefermodell zur Ausbildung von okklusalen Einprägungen in dem Tiefziehmaterial mit diesem in Kontakt ist.This object is achieved on the basis of a pressure molding apparatus of the type mentioned above in that a second holding unit for holding a counter-jaw model is arranged on the second chamber part, wherein the first and the second holding unit are arranged with closed pressure chamber to each other, that the opposing jaw model for the formation of Occlusal impressions in the thermoforming material is in contact with this.
Mit dem erfindungsgemäßen Druckformgerät können hochwertige Dentalschienen mit okklusalen Einprägungen auf einfache Art und Weise hergestellt werden. Bislang war es hierzu nämlich erforderlich, eine zum Beispiel mit dem aus
Die Ausbildung der okklusalen Einprägungen in dem Tiefziehmaterial erfolgt bei dem erfindungsgemäßen Druckformgerät bereits beim Schließen der Druckkammer, da das Tiefziehmaterial vorab auf eine geeignete Tiefziehtemperatur gebracht worden und somit durch den Kontakt mit dem Gegenkiefermodell in der geschlossenen Druckkammer zur Ausbildung der okklusalen Einprägungen plastisch verformbar ist. Dieser Kontakt zwischen dem Tiefziehmaterial und dem Gegenkiefermodell wird während des Tiefziehens des Tiefziehmaterials beibehalten.The formation of the occlusal imprints in the thermoforming material takes place in the pressure molding apparatus according to the invention already when closing the pressure chamber, since the thermoforming material has been previously brought to a suitable deep drawing temperature and thus plastically deformable by the contact with the opposing jaw model in the closed pressure chamber to form the occlusal imprints. This contact between the thermoforming material and the opposing jaw model is maintained during thermoforming of the thermoforming material.
Vor dem Anordnen von Kiefer- und Gegenkiefermodell an den Halteeinheiten der Kammerteile werden Kiefer- und Gegenkiefermodell vorzugsweise mittels eines Artikulators in die Stellung zueinander gebracht, die der gewünschten okklusalen Stellung der Kiefer eines Patienten entspricht. Diese Stellung von Kiefer- und Gegenkiefermodell wird über eine entsprechende Positionierung der Halteeinheiten auf das Druckformgerät übertragen.Prior to placing jaw and mandibular model on the support units of the chamber parts, jaw and opposing jaw models are preferably brought into position with each other by means of an articulator, which corresponds to the desired occlusal position of the jaws of a patient. This position of the mandibular and opposing jaw models is transferred to the compression molding device via a corresponding positioning of the holding units.
Nach einer vorteilhaften Ausgestaltung der Erfindung sind die beiden Kammerteile über ein einziges Gelenk schwenkbeweglich miteinander verbunden. Das Druckformgerät weist nach dieser Ausgestaltung einen relativ einfachen Aufbau auf und ist somit auf einfache Art und Weise anwendbar. Zudem ermöglicht diese Ausgestaltung zuverlässig die Herstellung von hochwertigen Dentalschienen mit geringsten Fertigungstoleranzen. Sind die beiden Kammerteile derart um das Gelenk zueinander verschwenkt, dass die Druckkammer geschlossen ist, werden unmittelbar die okklusalen Einprägungen in dem Tiefziehmaterial ausgebildet.According to an advantageous embodiment of the invention, the two chamber parts are pivotally connected to each other via a single joint. The pressure molding apparatus according to this embodiment has a relatively simple structure and is thus applicable in a simple manner. In addition, this configuration allows reliable production of high-quality dental splints with the lowest manufacturing tolerances. If the two chamber parts are pivoted to one another around the joint in such a way that the pressure chamber is closed, the occlusal imprints are formed directly in the thermoforming material.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Position der ersten Halteeinheit relativ zum ersten Kammerteil und/oder die Position der zweiten Halteeinheit relativ zum zweiten Kammerteil veränderbar sind. Diese Ausgestaltung ermöglicht die Übertragung der Stellung der beispielsweise mittels eines Artikulators einartikulierten Kiefermodelle auf die Positionierung der Halteeinheiten der Kammerteile.A further advantageous embodiment of the invention provides that the position of the first holding unit relative to the first chamber part and / or the position of the second holding unit relative to the second chamber part are variable. This embodiment makes it possible to transfer the position of the jaw models articulated in, for example, by means of an articulator, to the positioning of the holding units of the chamber parts.
Eine hierzu alternative Ausgestaltung der Erfindung sieht vor, dass die erste Halteeinheit und/oder die zweite Halteeinheit jeweils eine Halteplatte aufweisen, an denen Klemmelemente angeordnet sind, deren Stellung relativ zu der Halteplatte veränderbar ist. Hierdurch lässt sich die Stellung des Kiefermodells bzw. des Gegenkiefermodells auf gewünschte Art und Weise variieren, ohne eine Halteeinheit insgesamt relativ zu einem Kammerteil bewegen zu müssen.An alternative embodiment of the invention provides that the first holding unit and / or the second holding unit each have a holding plate on which clamping elements are arranged whose position is variable relative to the holding plate. In this way, the position of the jaw model or the opposing jaw model can be varied in a desired manner, without having to move a holding unit as a whole relative to a chamber part.
