Abstract

Pre-wall stabiliser for the production of dental prostheses in the form of an integrally formed profiled section comprising a vertical wall part and a cover plate essentially at right angles thereto. The ground plan of the profiled section is shaped such that it is adapted to the course of the particular dental region to be worked on which rests against it and is on the model side.

Description

Die Anwendung des Vorwallstabilisators wird in F i g. 3 gezeigt. Der Wandteil 2 schließt mit der Modellsockelplatte 20 ab. Zwischen dem Wandteil 2 der Deckplatte 3 und dem Prothesenmaterial 22 befindet sich die Siliconmasse 21, die durch den Vorwallstabilisator gehalten wird. Aus der Figur ist auch der rechtwinklige Aufbau des Vorwallstabilisators ersichtlich. In Wandteil und Deckplatte können, hier nicht dargestellt, Bohrungen bzw. Durchbrechungen vorgesehen werden, die beim Andrücken des Vorwallstabilisators ein Austreten von Siliconmasse erlauben. The application of the matrix stabilizer is shown in FIG. 3 shown. The wall part 2 ends with the model base plate 20. Between the wall part 2 of the cover plate 3 and the prosthesis material 22 is the silicone compound 21, which is held by the matrix stabilizer. From the figure is also the right-angled one Structure of the matrix stabilizer can be seen. In wall part and cover plate can, not shown here, holes or openings can be provided, which allow silicone compound to escape when the matrix stabilizer is pressed on.

In F i g. 4 sind verschiedene Ausführungsformen des Vorwallstabilisators gezeigt, wobei der Einfachheit halber jeweils ein Horizontalschnitt durch den Wandteil dargestellt ist. Die beiden Teile A und C mit geradem Verlauf dienen zur Herstellung oder zur Reparatur von seitlichen Prothesenteilen. Die gleiche Funktion hat die Ausführungsform F; die aber nur etwa halb so lang ist wie die Ausführungsformen A und C und für kleinere Teile bzw. Reparaturarbeiten eingesetzt werden kann. In Fig. 4 are different embodiments of the matrix stabilizer shown, for the sake of simplicity in each case a horizontal section through the wall part is shown. The two parts A and C with a straight course are used for production or to repair lateral parts of the prosthesis. The has the same function Embodiment F; but which is only about half as long as the embodiments A and C and can be used for smaller parts or repair work.

Die Ausführungsformen A, C und F entsprechen der Bauart nach Fig. 1. Die Ausführungsform B entspricht in etwa der Ausführungsform nach F i g. 2 und ist zur Anwendung im vorderen Bereich des Gebisses bestimmt.The embodiments A, C and F correspond to the type of Fig. 1. The embodiment B corresponds approximately to the embodiment according to FIG. 2 and is intended for use in the front area of the dentition.

Weitere Ausführungsformen des Vorwallstabilisators sind in der F i g. 5 wiederum als Horizontalschnitt des Wandteils dargestellt. Die beiden Ausführungsformen G und H können einzeln bei der Herstellung einer Prothesenhälfte Verwendung finden. Es ist aber auch möglich, wie dies in F i g. 5 gezeigt wird, sie zusammenzulegen, um so einen Vorwallstabilisator für eine Vollprothese zu erhalten. Further embodiments of the matrix stabilizer are shown in FIG i g. 5 again shown as a horizontal section of the wall part. The two embodiments G and H can be used individually in the manufacture of a prosthesis half. But it is also possible, as shown in FIG. 5 is shown to merge them, in order to obtain a matrix stabilizer for a full denture.

Die gezeigten Vorwallstabilisatoren können aus unterschiedlichen Materialien hergestellt werden. Besonders vorteilhaft ist die Anwendung von Kunststoffen, wobei hier zur Verbesserung der Stabilität harte Kunststoffe vorzuziehen sind. Es ist jedoch aber auch möglich, den Vorwallstabilisator aus metallischen, keramischen und anderen harten Werkstoffen zu fertigen. The matrix stabilizers shown can be made from different Materials are made. The use of plastics is particularly advantageous, Hard plastics are to be preferred here to improve stability. It however, it is also possible to use the matrix stabilizer made of metallic, ceramic and other hard materials.
