Beschreibungdescription

Die vorliegende Erfindung dient der intraoperativen Lagebestimmung von Zahnwurzeln, deren Wurzelkanal (bzw. -kanäle) eröffnet und aufbereitet, d.h. erweitert sind.The present invention is used for intraoperative position determination of tooth roots, the root canal (or canals) of which have been opened and prepared, i.e. expanded.

Bisher wurde die Lage einer Zahnwurzel, insbesondere der Wurzelspitze, intraoperativ anhand der Lage der Juga alveolaria oder eines in den Wurzelkanal gesteckten Instrumentes abgeschätzt. Dieses Vorgehen ist bei aboral gelegenen Wurzelspitzen einfach, bei den weiter oral gelegenen jedoch sehr unsicher, sofern der übliche, vestibuläre Operationszugang gewählt wird. Um die gewünschte Wurzelspitze darzustellen muß deshalb bei den bisherigen Verfahren entsprechend ausgedehnt osteotomiert werden.So far, the position of a tooth root, especially the tip of the root, estimated intraoperatively based on the position of the juga alveolaria or an instrument inserted into the root canal. This procedure is simple for aborally located root tips, but very unsafe for those located further orally, provided that the the usual vestibular surgical approach is chosen. In order to represent the desired root tip, you must therefore use the previous Procedure to be extended osteotomized accordingly.

Die vorliegende Erfindung dient der einfachen und exakten intraoperativen Lagebestimmung einer Wurzelspitze vor und bei einer Osteotomie. Dazu wird eine Lichtquelle über ein konvexes Linsensystem verkleinert abgebildet. In dem Bildpunkt befindet sich ein Ende eines flexiblen Lichtleiters. Das andere Ende wird wie 3in Wurzelkanalinstrument in den aufbereiteten Kanal bis zur Wurzelspitze vorgeschoben. Nach leichter Verdunkelung der extraoralen Operationsbeleuchtung wird die Position dar Wurzelspitze diaphanoskopisch durch das Helligkeitsmaximum angezeigt.The present invention is used for simple and accurate intraoperative Determination of the position of a root tip before and during an osteotomy. To do this, a light source is placed over a convex Lens system shown reduced. One end of a flexible light guide is located in the image point. The other end will like 3 in a root canal instrument into the prepared canal up to the tip of the root. After slight darkening of the extraoral Operating lighting, the position of the root tip is indicated diaphanoscopically by the maximum brightness.

Bei dem in der Abbildung dargestellten Ausführungsbeispiel wird der Glühfaden einer Projektionslampe (1) über ein konvexes Linsenoystem mit großem Durchmesser und kurzer Brennweite (2) stark verkleinert abgebildet. In dem RiZdpunkt befindet sich ein Ende des Lichtleiters (3) . Das zweite Ende is* auf einer Länge von etwa 30 mm abisoliert. Es wird in den Wurzelkanal eines Zahnes (4) geführt und erhellt den umliegenden Knochen (5). Es stehen verschiedene Lichtleiter zur Verfügung, die gegeneinander ausgetauscht werden können , Sie unterscheiden sich erstens in Ihren Durchmessern, die etwa zwischen 0,2 mm und 2 mm liegen, und zweitens in der Form ihre!? Enden, die stumpf oder spitz (6) auslaufen können.In the embodiment shown in the figure, the filament of a projection lamp (1) via a convex lens system with a large diameter and short focal length (2) shown greatly reduced. There is an end in the RiZdpunkt of the light guide (3). The second end is * for a length of stripped about 30 mm. It is inserted into the root canal of a tooth (4) and illuminates the surrounding bone (5). There are different light guides are available, which can be interchanged, they differ firstly in Their diameters, which are roughly between 0.2 mm and 2 mm, and, secondly, their shape !? Ends that are blunt or pointed (6) can leak.
