Description
Durch die vorliegende Erfindung wird die Aufgabe gelöst, einen Zahn zylindrisch zuzuschleifen, ohne durch benachbarte Zähne in dieser Tätigkeit behindert zu sein. The present invention solves the problem, a tooth To be ground cylindrically without being hindered in this activity by neighboring teeth to be.
Das Zuschleifen des Zahnes, welches notwendig ist, um eine Krone auf einen naturgewachsenen Zahn aufzusetzen, erfolgte bisher mittels Schleifräder, wodurch von außen her versucht wird, dem Zahn eine zylindrische Form zu geben, um die jeweilige Art der Krone in lückenlose Verbindung mit dem Naturzahn zu bringen. Dabei sind aber Nachhnrzähne bei der Bearbeitung hinderlich, so daß das Schleifergebris nicht zylindrisch, sondern unregelmäßige prismatische Form mit scharfen Graten und Kanten annimmt. Eine lückenlose Verbindung von Naturzahn und Krone ist daher kaum erzielbar und die Entstehung neuer Karies an den Übergangsstellen nicht völllig vermeidbar. The grinding of the tooth, which is necessary to make a crown to be placed on a naturally grown tooth was previously done using grinding wheels, whereby it is tried from the outside to give the tooth a cylindrical shape in order to to bring the respective type of crown into seamless connection with the natural tooth. But rear teeth are a hindrance during processing, so that the grinder teeth not cylindrical but irregular prismatic shape with sharp ridges and Edges. There is therefore hardly any gap between the natural tooth and the crown achievable and the development of new caries at the transition points is not complete avoidable.
Entsprechend der Erfindung wird der zu bearbeitende Zahn mittels eines endlosen Schleifbandes, auf der Darstellung mit C bezeichnet, halbseitig umschlossen, welches von einem Antriebsrad im Gehäuse B in gleichgerichtete Bewegung versetzt wird. Damit das Schleifband das Zahnfleisch nicht verletzt, dient die Einstellschraube E, welche am Zahn selbst aufsitzt und eine Bewegung des Schleifbandes in Richtung Zahnwurzel bzw. Zahnfleisch verhindert. Die Teile B, C und E sind drehbar um. die Achsrichtung des Antriebsrades am Schaft A befestigt, welcher auf das übliche Handstück F der zahnärztlichen Bohrmaschine aufgesteckt wird. According to the invention, the tooth to be machined is by means of an endless sanding belt, marked with C on the illustration, enclosed on one side, which is set in rectified motion by a drive wheel in housing B. will. The adjustment screw is used so that the grinding belt does not damage the gums E, which sits on the tooth itself and a movement of the grinding belt in the direction Tooth roots or gums prevented. Parts B, C and E are rotatable around. the Axial direction of the drive wheel attached to the shaft A, which is attached to the usual handpiece F is attached to the dental drill.
Das Gehäuse B besitzt zwei Schlitze, durch welche das Schleifband geführt ist, und außen eine Riffelung, welche die Drehung am Schaft A erleichtert, so daß der Zahn von allen Seiten bearbeitet werden kann. The housing B has two slots through which the sanding belt is guided, and on the outside a corrugation, which facilitates the rotation on the shaft A, so that the tooth can be worked on from all sides.
Das Schleifband C ist'oder wird mit der Schleifmasse bestrichen und besitzt regelmäßige Querschlitze, in welche einerseits das Antriebsrad eingreift, andererseits das Schleifmehl sich selbständig entfernt. The sanding belt C is' or is coated with the sanding compound and has regular transverse slots into which the drive wheel engages on the one hand, on the other hand, the grinding dust is removed by itself.
Das Antriebs rad wird mittels üblicher Art innerhalb des Schaftes durch die zahnärztliche Bohrmaschine in drehende Bewegung versetzt. The drive wheel is by means of the usual type within the shaft set in rotating motion by the dental drill.
Bei der Bearbeitung des Zahnes wird das Schleifbland C über den Zahn geschoben, die Begrenzung gegen das Zahnfleisch hin mittels der BegrenzungsschraubeE eingestellt, das Gerät in Gang gesetzt und der Zahn durch leichten Zug am Gerät bearbeitet. When machining the tooth, the grinding area C is placed over the tooth pushed, the limitation towards the gums by means of the limitation screw E. set, the device is started and the tooth is removed by pulling gently on the device processed.
