Abstract

The cylindrical implantation body is fixed in a corresp. recess in the jawbone and into it is screwed a holder for the tooth replacement part. The holder (6,7) with a threaded pin (8) engages in an adjustment ball (4,5) which is supported in a pressure bearing (2) in the implantation body, against which it is pressed by means of an axially inserted ring screw (3) in the implantation body. The adjustment ball (4,5) is divided in the ratio of 2/3:1/3 into upper (4) and lower (5) sections, of which the larger upper section accommodates the threaded pin (8) of the holder (6,7) which projects into the lower smaller ball section with a threadless centering extension (9). USE - Dental implant permanently fixed in patient's jaw.

Description

Die Erfindung bezieht sich auf ein zahnmedizinisches Im­ plantat zum Befestigen eines Zahnersatzteiles am Kiefer­ knochen, wobei ein zylindrischer Implantationskörper in einer entsprechenden Ausnehmung des Kieferknochens be­ festigt und eine für das Zahnersatzteil bestimmte Hal­ terung darin eingeschraubt wird.The invention relates to a dental Im implant for attaching a denture part to the jaw bone, with a cylindrical implant body in a corresponding recess in the jawbone strengthens and a Hal intended for the dental prosthetic item screwed into it.

Bisher bekannte Implantate dieser Art haben den Nachteil, daß sich die in den Implantationskörper eingeschraubten Halterungen nur insofern für das spannungsfreie Aufsetzen sowie dauerhafte Befestigen des Zahnersatzteiles gegen­ einander ausrichten lassen, als die Halterung nachträg­ lich bearbeitet wird. Eine solche schwierige nachträg­ liche Bearbeitung ist jedoch stets unumgänglich, weil es aufgrund der bestehenden Gegebenheiten grundsätzlich nicht gelingt, die für die Implantationskörper bestimmten Ausnehmungen im Kieferknochen absolut parallel anzubrin­ gen, wie es sonst erforderlich wäre. Hier für Abhilfe zu sorgen, ist die Aufgabe der Erfindung.Known implants of this type have the disadvantage that the screwed into the implant body Holders only insofar as the tension-free attachment as well as permanent fastening of the denture part against align each other when the bracket is added is processed. Such a difficult afterthought However, processing is always unavoidable because it basically due to the existing circumstances not succeed, those intended for the implant body  Make recesses in the jawbone absolutely parallel conditions as would otherwise be required. Here for remedy to worry is the object of the invention.

Die von der Erfindung zur Lösung der gestellten Aufgabe vorgeschlagenen Maßnahmen gehen aus den Ansprüchen her­ vor.That of the invention to achieve the object proposed measures are based on the claims in front.

Mit dem neuartigen Implantat ist es nunmehr aufgrund der allseits gelenkigen Lagerung der für das Zahnersatzteil bestimmten Halterung möglich, diese erst im Anschluß an das Einsetzen des Implantationskörpers in den Kieferkno­ chen sowie dem Verheilen der Wunde im Implantationskörper anzubringen und anschließend nach Bedarf im Implanta­ tionskörper auszurichten. Letzteres gilt auch für even­ tuell infolge von Kieferveränderungen vorzunehmende Kor­ rekturen. Außerdem wird durch das Spreizen des Implan­ tationskörpers dessen Halt im Kieferknochen weitgehend verbessert, ohne jedoch sein gegebenenfalls später not­ wendig werdendes Entfernen aus dem Kieferknochen zu er­ schweren. Ebenso läßt sich der Innenraum des Implanta­ tionskörpers für irgendwelche medikamentösen Behandlungen jederzeit wieder zugänglich machen.With the novel implant, it is now due to the hinged storage on all sides for the dental prosthesis certain bracket possible, this only after inserting the implant body into the jawbone Chen and the healing of the wound in the implant body attached and then as needed in the implant alignment body. The latter also applies to even Correction to be made as a result of changes in the jaw rectifications. In addition, by spreading the implan tion body whose hold in the jawbone largely improved, but may not be necessary later maneuverable removal from the jawbone heavy. The interior of the Implanta can also be used body for any drug treatments make it accessible again at any time.
