Description

Stiftloser künstlicher Zahn, insbesondere .zur auswechselbaren Verbindung mit- metallenen Rückenplatten Die Erfindung bezieht sich.auf eine weitere Ausführung des Zahnes nach Patent 503 420, die den Zahn für Metallarbeiten verwendbar macht.Pinless artificial tooth, especially for interchangeable connection with metal back plates. The invention relates to a further design of the tooth according to patent 503 420, which makes the tooth usable for metal work.

Gemäß der Erfindung besitzt der Zahn nach der Kaufläche zu Kanäle, Einschnitte in den Längskanälen, in welche Anker von Rückenplatten eingreifen, die nach dem Zahnhalse zu mittels Zapfen in den Hohlraum bzw. die Kanäle des Zahnes hineinreichen.According to the invention, the tooth has canals after the occlusal surface, Incisions in the longitudinal channels in which anchors from back plates engage after the neck of the tooth by means of pegs into the cavity or the canals of the tooth reach in.

In der Zeichnung ist diese Ausführungsform veranschaulicht, und zwar zeigt: Abb. i einen Aufriß der Rückseite des Zahnes, Abb. 2 einen Längsschnitt des Zahnkörpers mit eingesetzter Rückenplatte, Abb. 3 die-Rückenplatte in Rückansicht in. nicht am Zahnhalse angebogenem Zustand, Abb. 4 einen Längsschnitt mit eingesetzter Rückenplatte mit anderen Verankerungsmitteln.In the drawing, this embodiment is illustrated, namely shows: Fig. i an elevation of the back of the tooth, Fig. 2 a longitudinal section of the Tooth body with inserted back plate, Fig. 3 the back plate in rear view in. not bent at the tooth neck, Fig. 4 a longitudinal section with inserted Back plate with other anchoring means.

Der Zahn ist als Absatzzahn ausgebildet und hat vom Absatz nach der Zahnhalsseite zu außer den in aufrechter Rechteckform austretenden Kanalöffnungen keinerlei Vorsprünge und Durchbrechungen. Die Kanäle b bilden nach der Kaufläche zu Einschnitte e, in welche die Anker f der Rückenplatte g (Abb.z) beim Aufkitten des Zahnes eingreifen und dadurch in der Nähe der Kaufläche festen Halt bekommen. Außer den Ankern f sind an den Rückenplatten noch Zapfen h von runder oder Prismenform mit und ohne Unterschnitte angebracht, welche sich in dem mit Zement gefüllten Hohlraum c des Zahnhalses verankern und so den Rückenplatten auch am Zahnhalse noch weiteren Halt geben: Abb. 4 zeigt .den Zahn mit einer Rückenplatte i mit zwei Ankerzapfen k, welche vom Zahnhalse aus der Länge nach in die Kanäle eingeführt und mit Zement festgekittet sind.The tooth is designed as a shoulder tooth and, apart from the channel openings emerging in an upright rectangular shape, has no protrusions or perforations from the shoulder to the tooth neck side. The channels b form incisions e after the chewing surface, in which the anchors f of the back plate g (Fig.z) engage when the tooth is cemented and thus get a firm hold in the vicinity of the chewing surface. In addition to the anchors f, pegs h of round or prismatic shape with and without undercuts are attached to the back plates, which anchor themselves in the cement-filled cavity c of the tooth neck and thus give the back plates even more support on the tooth neck: Fig. 4 shows. the tooth with a back plate i with two anchor pins k, which are inserted lengthwise from the tooth neck into the canals and cemented with cement.

Durch diese Formgebung und Anordnung der Ankerhaken f und h an den Rückenplatten g (Abb. 2 und 3) und der Ankerzapfen k an den Rückenplatten i (Abb. 4). ist eine sehr leichte Auswechselung der Zähne an Metallbrücken möglich.This shape and arrangement of the anchor hooks f and h on the back plates g (Fig. 2 and 3) and the anchor pin k on the back plates i (Fig. 4). it is very easy to change the teeth on metal bridges.
