Die vorliegende Neuerung betrifft einen gebogenen Dental-Lichtstab zur Verwendung in Verbindung mit Lichtgeräten in der Dentaltechnik.This innovation concerns a curved dental light rod for use in conjunction with light devices in dental technology.
Durch Licht härtende Zahnfül1ungs- und -Versiegelungsmaterialien (lichthärtende Composites) besitzen in der modernen Dentaltechnik große Bedeutung.Light-curing dental filling and sealing materials (light-curing composites) are of great importance in modern dental technology.
Beim Arbeiten mit lichthärtenden Composites wird mittels eines Dental-Lichtstabs - das ist ein aus einer Vielzahl von Lichtleitfasern aufgebauter, starrer Lichtleiter - intensives Licht (Polymerisutionslicht) im Wellenlängenbereich von ungefähr 400 bis 500 nm auf die zu bearbeitende Stelle des Gebisses des Patienten einwirken gelassen.When working with light-curing composites, intensive light (polymerization light) in the wavelength range of approximately 400 to 500 nm is shined onto the area of the patient's teeth that is to be treated using a dental light rod - this is a rigid light guide made up of a large number of optical fibers.
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 einer Halogenlampe, eingesetzt.In order to be able to apply the polymerization light from the working position of the dentist, who usually sits or stands to the side behind or next to the patient, in a comfortable position of the handle, the application end of the dental light rod must be bent. The other end of the dental light rod, where the light is coupled into it, is inserted into the handle of the light source, usually a halogen lamp.
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.By creating the bend, bubbles are created in such a dental light rod, especially in the area of the bend, which, among other things, affect the overall visual 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.

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 ungefähr 1600C thermisch belastbar ist.The aim of this innovation is to produce a dental light stick that does not emit any scattered light and that is particularly simple and inexpensive to manufacture. In addition, this new dental light stick must meet the requirement that it can be sterilized with hot steam, i.e. that it can withstand temperatures of up to approximately 160 ° C.
Dieses Ziel wird mit einem Lichtleitstab gemäß den Schutzansprüchen erreicht.This goal is achieved with a light guide rod in accordance with the protection claims.
Gemäß einer bevorzugten Ausführungsform ist der Dental-Lichtstab mit einer optisch dichten Schicht, hergestellt aus Diffusionsfarbe, beschichtet.According to a preferred embodiment, the dental light rod is coated with an optically dense layer made of diffusion paint.
Die Neuerung wird anhand der Zeichnung näher erläutert, in weleherThe innovation is explained in more detail using the drawing, in which
Figur 1 eine Seitenansicht eines erfindungsgemäßen Dental-Lichtstabes ist undFigure 1 is a side view of a dental light stick according to the invention and
Figur 2 ein Schnitt entlang der Linie H-II des Dental-Lichtstabes von Fig. 1 ist.Figure 2 is a section along the line H-II of the dental light stick of Fig. 1.
In Figur 1 ist ein erfindungsgemäßer 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 Lichteinkoppel-Figure 1 shows a dental light rod 1 according to the invention. The dental rod 1, which is bent at 3, is covered with a protective layer 2 on its outer surface. This protective layer 2 has such an optical density that no scattered light can be emitted from the light coupling device.
