   BESCHREIBUNG



   Die vorliegende Neuerung betrifft einen gebogenen Dental-Lichtstab zur Verwendung in Verbindung mit Lichtgeräten in der   Dentaltechnik.   



   Durch Licht härtende Zahnfüllungs- und -Versiegelungsmaterialien (lichthärtende Composites) besitzen in der modernen Dentaltechnik grosse Bedeutung.



   Beim Arbeiten mit lichthärtenden Composites wird mittels eines   Dental-Lichtstabs - das    ist ein aus einer Vielzahl von Lichtleitfasern aufgebauter, starrer   Lichtleiter - inten-    sives Licht   (Polymerisationsücht)    im Wellenlängenbereich von ungefähr 400 bis 500 nm auf die zu bearbeitende Stelle des Gebisses des Patienten einwirken gelassen.



   Um aus der Arbeitsposition des Zahnarztes, der für gewöhnlich seitlich hinter oder neben dem Patienten sitzt oder steht, in bequemer Haltung des Handgriffs das Polymerisationslicht applizieren zu können, muss das anwendungsseitige Ende des Dental-Lichtstabes abgebogen sein. Das andere Ende des Dental-Lichtstabes, an dem das Licht in diesen eingekoppelt wird, ist in den Handgriff der Lichtquelle, meist eine Halogenlampe, eingesetzt.



   Durch die Erzeugung der Biegung entstehen in einem solchen Dental-Lichtstab vor allem im Bereich der Biegung Blasen, die   u.    a. den optischen Gesamteindruck des fertigen Dental-Lichtstabes beeinträchtigen. Was viel schwerer wiegt, ist jedoch, dass sowohl der Patient als auch der Zahnarzt dem von dem Lichtstab ausgehenden (intensiven) Streulicht ausgesetzt sind.



   Es ist bereits versucht worden, das Problem des   Streu-    lichts dadurch zu umgehen, dass die geraden Abschnitte eines solchen Dental-Lichtstabes, also das der Lichtquelle zugewandte Ende und das anwendungsseitige Ende, mit je einer Metallhülse ummantelt werden und der Bereich der Biegung durch ein Stück eines für den vorliegenden Verwendungszweck geeigneten Schrumpfschlauches passender Länge umschlossen wird. Die Herstellung eines Dental-Lichtstabes der hier beschriebenen Art ist sehr aufwendig.



   Ziel der vorliegenden Neuerung ist ein Dental-Lichtstab, der kein Streulicht abgibt und der besonders einfach und billig herzustellen sein soll. Ausserdem soll dieser neue Dental Lichtstab der Forderung genügen, dass er heissdampfsterilisierbar ist, dass er also bis ungfähr 160   0C    thermisch belastbar ist.



   Dieses Ziel wird mit einem gebogenen Dental-Lichtstab gemäss Patentanspruch   1    erreicht.



   Gemäss einer bevorzugten Ausführungsform ist der Dental-Lichtstab mit einer optischen Schicht, hergestellt aus Diffusionsfarbe, beschichtet.



   Die Neuerung wird anhand der Zeichnung näher erläutert, in welcher
Figur   1    eine Seitenansicht eines   erlindungsgemässen    Dental-Lichtstabes ist und
Figur 2 ein Schnitt entlang der Linie   II - II    des Dental Lichtstabes von Fig. list.



   In Figur list ein   erffndungsgemässer    Dental-Lichtstab   1    dargestellt; der Dentalstab 1, der bei 3 gebogen ist, ist auf seiner Mantelfläche mit einer Schutzschicht 2 überzogen.



  Diese Schutzschicht 2 weist eine derartige optische Dichte auf, dass kein Streulicht von dem am Lichteinkoppelende 4 eintretenden und an der Spitze 5 des Stabes austretenden Licht durch diese Schutzschicht 2 dringen kann. Gemäss einer bevorzugten Ausführungsform der Neuerung besitzt der Dental-Lichtstab   1    eine Schutzschicht 2, die mittels Diffusionsfarbe erzeugt wurde.



   Figur 2 zeigt, wie der Dental-Lichtstab   1    aus einem starren Bündel aus einzelnen Lichtleitfasern 6 besteht und mit der Schutzschicht 2 überzogen ist. 



  
 



   DESCRIPTION



   The present innovation relates to a curved dental light rod for use in connection with lighting devices in dental technology.



   Light-curing tooth filling and sealing materials (light-curing composites) are of great importance in modern dental technology.



   When working with light-curing composites, a dental light rod - this is a rigid light guide made up of a large number of optical fibers - will act on the light to be processed on the patient's dentition in the wavelength range from approximately 400 to 500 nm calmly.



   In order to be able to apply the polymerization light from the working position of the dentist, who usually sits or stands laterally behind or next to the patient, in a comfortable position of the handle, the end of the dental light rod on the application side must be bent. The other end of the dental light rod, at which the light is coupled into it, is inserted into the handle of the light source, usually a halogen lamp.



   The generation of the bend creates bubbles in such a dental light rod, especially in the area of the bend, which u. a. affect the overall optical impression of the finished dental light rod. What is much more serious, however, is that both the patient and the dentist are exposed to the (intense) scattered light emanating from the light rod.



   Attempts have already been made to circumvent the problem of the scattered light by encasing the straight sections of such a dental light rod, that is to say the end facing the light source and the end on the application side, with a metal sleeve and the area of the bend through Piece of a suitable length of heat shrink tubing suitable for the present purpose is enclosed. The production of a dental light rod of the type described here is very complex.



   The aim of the present innovation is a dental light rod that does not emit scattered light and that should be particularly simple and inexpensive to manufacture. In addition, this new dental light rod should meet the requirement that it can be sterilized by hot steam, that it can therefore withstand thermal loads of up to approximately 160 ° C.



   This goal is achieved with a curved dental light rod according to claim 1.



   According to a preferred embodiment, the dental light rod is coated with an optical layer made of diffusion color.



   The innovation is explained in more detail with reference to the drawing, in which
Figure 1 is a side view of a dental light rod according to the invention and
FIG. 2 shows a section along the line II-II of the dental light rod from FIG. List.



   FIG. 1 shows a dental light rod 1 according to the invention; the dental rod 1, which is bent at 3, is coated on its outer surface with a protective layer 2.



  This protective layer 2 has an optical density such that no scattered light from the light entering the light coupling end 4 and exiting at the tip 5 of the rod can penetrate through this protective layer 2. According to a preferred embodiment of the innovation, the dental light rod 1 has a protective layer 2 which was produced by means of diffusion color.



   FIG. 2 shows how the dental light rod 1 consists of a rigid bundle of individual optical fibers 6 and is covered with the protective layer 2.
