Abstract
Description
Lichtpolymerisation von dentalen Kunststoffen ist ein in jüngster Zeit immer mehr bevorzugtes Verfahren zur Endaus härtung von in Kunststoff modellierten Zahnformen. Während bei lichthärtenden Zahnfüllungen die dichte manuelle Adaptation eines Lichtleiters ausreicht, werden im zahntechnischen Bereich geschlossene Geräte hoher Lichtleistung verwendet, bei denen bogenförmige oder runde Lichtquellen, z. B. Xenonblitzröhren oberhalb der zu polymerisierenden Objekte angeordnet sind.Light polymerization of dental plastics is an in recently more and more preferred method for the end hardening of tooth molds modeled in plastic. While at light-curing dental fillings the tight manual adaptation of an optical fiber is sufficient in the dental field closed devices with high light output used, where arcuate or round light sources, e.g. B. Xenon flash tubes are arranged above the objects to be polymerized.
Um hierbei eine totale Durchleuchtung von voluminösen Objekten zu erhalten, ist eine sehr intensive Lichtquelle hoher Leistung erforderlich. Erwärmung mit thermischer Verformung und Abküh lungskontraktion der Werkstoffe sind neben den hohen Kosten die bekannten Nachteile dieses Verfahrens.In order to completely illuminate voluminous objects to get is a very intense light source of high power required. Warming with thermal deformation and cooling Contraction of the materials besides the high costs known disadvantages of this method.
Das erfindungsgemäße Lichtpolymerisationsgerät erlaubt es, mit geringer Lichtintensität eine zeitgesteuerte, allseitige Durch leuchtung des polymerisierenden Objektes durchzuführen.The light polymerization device according to the invention allows with low light intensity a time-controlled, all-round through to illuminate the polymerizing object.
Dieses Lichtpolymerisationsgerät für Dentalwerkstoffe ist da durch gekennzeichnet, daß mindestens eine Lichtquelle (1) in einem verschließbaren Gehäuse (2) über einer drehbaren Ebene (7) angeordnet ist, die von einem Elektromotor (4) im Strah lungsbereich (5) der Lichtquelle (1) gleichförmig oder nach Zeitprogrammierung intermittierend gedreht wird. Dadurch wird jede Seite des zu polymerisierenden Objektes in der vorge gebenen Zeiteinheit einmal oder wahlweise mehrfach automatisch lichtpolymerisiert. In einer besonders bevorzugten Ausführung führt die drehbare Ebene als Objektträger, bezogen auf den Drehwinkel, periodisch-intermittierende Drehungen aus.This light polymerization device for dental materials is characterized in that at least one light source ( 1 ) is arranged in a closable housing ( 2 ) above a rotatable plane ( 7 ) which is emitted by an electric motor ( 4 ) in the radiation region ( 5 ) of the light source ( 1 ) is rotated uniformly or intermittently according to time programming. As a result, each side of the object to be polymerized is automatically light-polymerized once or optionally several times in the specified time unit. In a particularly preferred embodiment, the rotatable plane performs periodically intermittent rotations as a slide, based on the angle of rotation.
In einer anderen bevorzugten Ausführung sind auf der Drehebene mehr als ein Objektträger angeordnet.In another preferred embodiment are on the level of rotation more than one slide arranged.
In einer weiteren Ausführungsform bewegen sich Lichtquelle und Drehebene simultan.In a further embodiment, the light source and Turning plane simultaneously.
Bei einer anderen erfindungsgemäßen Vorrichtung drehen sich mehrere auf der Drehebene angeordnete Objektträger selbst gleichzeitig um ihre Achse.In another device according to the invention rotate several slides arranged on the rotating plane itself around its axis at the same time.
Durch das erfindungsgemäße Lichtpolymerisationsgerät kann der Abstand zwischen Objekt und Lichtquelle sehr klein gewählt und die Geräteausführung entsprechend klein gehalten werden.By means of the light polymerization device according to the invention, the Distance between object and light source chosen very small and the device version must be kept correspondingly small.
