Description

Vorrichtung zur exakten und wiederholbaren Übertragung von zahnmedizinischen Halteelementen Device for the exact and repeatable transmission of dental holding elements
Die Erfindung betrifft eine Vorrichtung zur exakten und wiederholbaren Übertragung von zahnmedizinischen Halteelementen.The invention relates to a device for the exact and repeatable transmission of dental holding elements.
Der Übertragung von zahnmedizinischen Halteelementen von einem Objekt auf ein anderes, beispielsweise der Übertragung von intraoralen Brackets für festsitzende Zahnspangen, kommt in der zahnmedizinischen Praxis eine große Bedeutung zu. Derzeit werden zahnmedizinische Halteelemente von einem Objekt auf ein anderes im wesentlichen auf zwei Arten übertragen. Die eine Möglichkeit besteht in einer Kombination aus einem weichen und einem harten Material, wobei der weiche Teil formschlüssig mit dem Objekt verbindbar ist und das Halteelement trägt, wogegen der harte Teil den weichen Teil stützt und so die Form hält. Bei der anderen Möglichkeit sind die Halteelemente mit eigens angefertigten Verankerungsvorrichtungen für spezielle Übertragungsvorrichtungen versehen. Nachteilig an diesen Techniken ist, daß sie jeweils nur zum einmaligen Übertragen angewendet werden können und für eine neuerliche Übertragung neu angefertigt werden müssen.The transfer of dental holding elements from one object to another, for example, the transfer of intraoral brackets for fixed braces, in the dental practice is of great importance. Currently, dental support members are transferred from one object to another in essentially two ways. One possibility is a combination of a soft and a hard material, wherein the soft part is positively connected to the object and carries the holding element, whereas the hard part supports the soft part and thus holds the shape. In the other possibility, the holding elements are provided with specially made anchoring devices for special transmission devices. A disadvantage of these techniques is that they can each be used only for a single transfer and must be rebuilt for a new transfer.
Aufgabe der Erfindung ist es, die Halteelemente von einem Zahnmodell auf ein Gebiß zu übertragen, ohne die räumliche Relation zwischen Gebiß und Halteelement während des gesamten Übertragungsvorganges zu verlieren. Diese Aufgabe wird erfindergemäß dadurch gelöst, daß a) zur Erhaltung der Relation zwischen dem Zahnmodell und dem zahnmedizinischen Halteelement mindestens ein mit dem Zahnmodell formschlüssig in Eingriff versetzbares erstes Element angefertigt wird, b) mindestens ein zweites Element, auf dem das zahnmedizinische Haltelement befestigt werden kann, angefertigt wird, und c) mindestens eine Schiebeverbindung zwischen dem ersten und dem zweiten Element hergestellt wird, die es gestattet, das zweite Element derart zu bewegen, daß das zahnmedizinische Haltelement am Zahn angebracht werden kann.The object of the invention is to transfer the holding elements of a dental model to a denture, without losing the spatial relationship between the denture and retaining element during the entire transfer process. This object is inventively achieved in that a) to maintain the relation between the tooth model and the dental holding element at least one form-fitting engageable with the tooth model first element is made, b) at least one second element on which the dental support element can be attached is made, and c) at least one sliding connection between the first and second element is made which allows the second element to be moved such that the dental support element can be attached to the tooth.
Gegenstand der Erfindung ist auch eine Einrichtung zur exakten und wiederholbaren Übertragung von zahnmedizinischen Halteelementen von einem Zahnmodell auf einen Zahn, gekennzeichnet durch ein formschlüssig mit dem Zahnmodell in Eingriff versetzbares erstes Element und ein mit diesem durch mindestens eine Schiebeverbindung verbundenen zweiten Element, auf welchem das zahnmedizinische Haltelement befestigbar ist.The invention also provides a device for the exact and repeatable transfer of dental holding elements from a dental model to a tooth, characterized by a first element positively engageable with the dental model and a second element connected thereto by at least one sliding connection, on which the dental Holding element can be fastened.
Vorzugsweise wird zur Herstellung des ersten Elementes eine elastische oder aushärtende Masse verwendet, aus welcher das Element durch Gießen geformt wird. Alternativ kann die Form des ersten Elementes aus einer härteren Masse gefräst werden.Preferably, an elastic or hardening mass is used for the production of the first element, from which the element is formed by casting. Alternatively, the shape of the first element can be milled from a harder mass.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert .An embodiment of the invention will be explained in more detail with reference to the drawing.
Fig. 1 ist eine Vorderansicht einer Vorrichtung gemäß der Erfindung; Fig. 2 ist eine Seitenansicht der Vorrichtung nach Fig. 1; Fig. 3 ist eine Vorderansicht einer abgewandelten Ausführungsform und Fig. 4 ist eine Seitenansicht von Fig. 3.Fig. 1 is a front view of a device according to the invention; Fig. 2 is a side view of the device of Fig. 1; FIG. 3 is a front view of a modified embodiment, and FIG. 4 is a side view of FIG. 3.
Gemäß Fig. 1 wird an einem Zahnmodell 1 ein Bracket 2 festgelegt, das mit einem zugeordneten Träger 3 formschlüssig verbunden und beispielsweise mittels eines Gummiringes 4 gehalten ist. Der Träger 3 ist relativ zu dem Zahnmodell in einem Halter 5 verschiebbar, wie dies Fig. 2 zeigt. Im Zuge des Übertragungsvorganges wird zuerst ein Träger 3 angefertigt und relativ zum Zahnmodell, z.B. mittels eines Roboters, in die Zielposition gebracht. Sodann wird ein Halter 5 angefertigt, der formschlüssig mit dem Zahnmodell 1 und dem Träger 3 verbunden ist und die Endlagen fixiert .1, a bracket 2 is fixed to a dental model 1, which is positively connected to an associated carrier 3 and held for example by means of a rubber ring 4. The carrier 3 is displaceable relative to the tooth model in a holder 5, as shown in FIG. 2. In the course of the transfer process, a carrier 3 is first made and placed relative to the dental model, for example by means of a robot, in the target position. Then, a holder 5 is made, which is positively connected to the tooth model 1 and the carrier 3 and fixes the end positions.
Bei dem Ausführungsbeispiel nach den Fig. 1 und 2 ist das Übertragungselement 3 U-förmig, z.B. aus Draht, gefertigt, der im Halter 5 zentral geführt ist, wie dies Fig. 1 zeigt. Bei der Ausführungsform nach den Fig. 3 und 4 ist das Übertragungselement ein im wesentlichen L-förmiger Träger 3 ' , der im Halter 5 seitlich geführt ist.In the embodiment of Figures 1 and 2, the transmission element 3 is U-shaped, e.g. made of wire, which is guided centrally in the holder 5, as shown in FIG. 1. In the embodiment according to FIGS. 3 and 4, the transmission element is a substantially L-shaped carrier 3 ', which is guided laterally in the holder 5.
In der Praxis wird nach der Anfertigung des Modells der formschlüssig mit diesem in Eingriff stehende Halter 5 vom Zahnmodell 1 abgenommen, Bracket 2 mittels eines Gummiringes 4 auf Träger 3 festgelegt und auf einen Zahn im Gebiß transferiert. Das Bracket 2 wird nach dem erneuten Festlegen des Halters 5 am Zahn befestigt, indem der Träger 3 relativ zum Halter 5 in die Zielposition gegen den Zahn geschoben wird. In practice, after making the model of the form-fitting engaged with this holder 5 is removed from the dental model 1, set bracket 2 by means of a rubber ring 4 on support 3 and transferred to a tooth in the teeth. The bracket 2 is fixed to the tooth after re-setting the holder 5 by the carrier 3 is pushed relative to the holder 5 in the target position against the tooth.
