Description
"Meßraster für Röntgenbilder" Die Erfindung bezieht sich auf ein Meßtaster oder dergleichen, das sich auf dem Röntgenfilm oder -Bild als Maßstabf abbildet."Measurement grid for X-ray images" The invention relates to a measuring probe or the like that is reproduced on the X-ray film or image as a scale f.
Bisher muß zur Messung einer Zahnlange bei einer Wurzelkanalbehandlung erst der Wurzelkanal eröffnet, eine graduierte Meßsonds in den Wurzelkanal eingeführt und dann eine Röntgenaufnahme gemacht werden um festzustellen, wie weit das Medinstrument sich im Kanal befindet oder die Spitze des Instruments vom Wurzelkanalein-Drang entfernt ist. Die Zahn- und damit die Wurzelkanallänge kann somit erst während der Behandlung und mit Zeitverlust festgestellt werden.Until now, it was necessary to measure the length of a tooth during a root canal treatment only the root canal is opened, a graduated measuring probe is inserted into the root canal and then an x-ray will be taken to determine how far the medical instrument is located in the canal or the tip of the instrument from the root canal penetration away. The tooth and thus the root canal length can only be determined during the Treatment and with loss of time can be determined.
Bei der Entfernung von Fremdkörpern, zurückgebliebenen Wurzelresten oder Entzündungsherden im Knochen können diese röntgenologisch nur dadurch lokalisiert werden, dab durch Röntgenaufnahmen eine räumliche Nachbarschaftsbeziehung zur eingestochenen Nadel, clufgeklebtem röntgenundurchlässigem Material wie Guttapercha usw.When removing foreign bodies and remaining root residues or foci of inflammation in the bone can only be localized radiologically by this that a spatial neighborhood relationship to the pierced one through X-ray images Needle, cluf-glued radio-opaque material such as gutta-percha, etc.
hergestellt wird, um das Auffinden während der Operation zu er-Leichtern.is made to make it easier to find during surgery.
1)ie Messung von Taschentiefen zur Diagnostik von Erkrankungen des Zahnhalteappparates (Parodontopathien) mit graduierten Sonden ist zeitraubend und das Einbringen von Guttapercha-Spitzen zur Darstellung der krankhaften Taschentiefen vor einer Röntgenaufnahme imständlich.1) he measurement of pocket depths for diagnosing diseases of the Periodontal apparatus (periodontal disease) with graduated probes is time consuming and the introduction of gutta-percha points to show the pathological pocket depths inconvenient before an X-ray.
Alle diese Verfahren erübrigen sich durch einen Meßraster auf dem Röntgenbild, da sowohl die genaue Länge des behandelten Zahnes, wie der genaue Abstand eines Wurzelrestes oder dergl.-von Nachbarzähnen oder Knochenbegrenzungslinien oder auch Taschentiefen bei ahllbetterkrankungen vom Röntgenbild direkt abgelesen werden können.All these procedures are superfluous with a measuring grid on the X-ray, as both the exact length of the treated tooth and the exact distance a remnant of a root or the like - of neighboring teeth or bone boundary lines or Pocket depths can also be read directly from the X-ray image in the case of sickness in bed can.
Zur Läsung dieser Aufgabe sieht die Erfindung ein Röntgenkontrastfähiges Raster z. B. aus einem dünnen Metall, das als Dahtgitter oder Lochfolie zwischen dem Aufnahmeobäekt und dem Bild angeordnet ist, vor.To achieve this object, the invention provides an X-ray contrast capable Grid z. B. made of a thin metal as a wire mesh or perforated film between the receiving object and the image is arranged before.
Insbesondere wird vorgeschlagen: Drahtgitter oder Folie in Filmumhullung nach Figur 1 a) eingelegt, b) eingebettet, c) außen aufgeklebt, d) aufgedruckt oder aufgdstempelt.In particular, the following is proposed: wire mesh or foil wrapped in film according to Figure 1 a) inserted, b) embedded, c) glued on the outside, d) printed or stamped on.
Für die Verwendung neutralen Filmmaterials besteht erfindungsgemäß außer der Anbringung des Rasters nach 1a-d vorzugsweise der Rahmen nach den Figuren 2 a und b.According to the invention, neutral film material can be used apart from the attachment of the grid according to 1a-d, preferably the frame according to the figures 2 a and b.
Figur 2 a) Rahmen zum Einschieben, b) aufgespannter federnder Meßraster. Figure 2 a) frame for insertion, b) stretched spring measuring grid.
Außerdem beinhaltet die Erfindung die Möglichkeit einer Vorbelichtung, sowohl in der Filmherstellung als auch vor der eigentlicher.In addition, the invention includes the possibility of pre-exposure, both in film making and before the actual.
Röntgenaufnahme mit einem Geräte zusatz.X-ray with an additional device.
Die Ausbildung des Meßrasters, quadratisch, rechteckig oder zielscheibenförmig und die zusätzliche Anlage von Meßzahlen an den Außenseiten oder an einem mittigen Koordinatenkreuz hängt vom speziellen Verwendungszeck ab.The formation of the measuring grid, square, rectangular or target-shaped and the additional installation of measurement numbers on the outer sides or on a central one Coordinate cross depends on the specific purpose of use.
Für die Anwendung in der Endodontie (Wzelkanalbehandlung) wird eine Ausbildung des Rasters nach Figur 3 vorgeschlagen.For use in endodontics (root canal treatment) a Design of the grid according to Figure 3 proposed.
Die Rastereinteilung des Röntgenbildes (Abstand 2 mm) ermöglicht schon vor Eröffnung des Wurzelkanals das Ablesen der Wurzelkanallänge und somit die Auswahl eines Wurzelkanalbehandlungsinstruments mit der entsprebhenden Meßzahl auf dessen Skala. Eine Verlängerung oder Verkürzung des geröntgten Zahnes, bedingt durch Projektionsfehler, ist dabei unerheblich, da der Raster ja leichermaßen verlängert oder verkurzt erscheint und die abgelesenen Werte zarLenmäßig unbeseinflußt bleiben.The grid division of the X-ray image (distance 2 mm) already makes it possible Before opening the root canal, reading off the root canal length and thus making the selection of a root canal treatment instrument with the corresponding measurement number on its Scale. A lengthening or shortening of the X-rayed tooth, caused by projection errors, is irrelevant here, since the grid appears to be slightly elongated or shortened and the readings remain unaffected.
