Description

Beschreibung:Description:

In der Zahnmedizin werden zum Schutz von zerstörten Zähnen Schutzkronen verwendet. Diese müssen oftmals wieder entfernt werden. Da sie festzementiert oder geklebt sind, können sie meist nur durch vollständige Zerstörung abgenommen werden. Bei einer schonenden Kronenentfernung könnten sie jedoch wiedereingesetzt werden, was erheblich Aufwand und Kosten spart.In dentistry, protective crowns are used to protect damaged teeth. These often have to be removed again. Since they are cemented or glued, they can usually only be removed by completely destroying them. However, if the crown is removed carefully, they can be reinserted, which saves a lot of effort and money.

Sinn der Erfindung ist es diese Kronen möglichst einfach, schnell und schonend zu entfernen.The purpose of the invention is to remove these crowns as easily, quickly and gently as possible.

Dies geschieht mittels eines Stabes, der an seinem Ende einen schaufeiförmigen Keil mit unregelmäßig mehrflächiger facettenartiger Oberfläche besitzt.This is done by means of a rod that has a shovel-shaped wedge with an irregular, multi-faceted surface at its end.

Nach der Trepanation der Krone mittels eines Bohrers, wird der Keil unter die Krone eingepreßt, so daß sich die Krone vom Zahn lösen muß. Hierbei können durch die unregelmäßig facettenartige Oberflächengestaltung des Keiles je nach Schubrichtung verschieden starke, jeweils angemessene Kräfte und Hebelwirkungen erzielt werden. Durch die schaufelartige Gesamtform des Keiles entseht auf der Rückseite eine Retentionskante, mittels der auch starke Abzugskräfte auf die Krone ausgeübt werden können.After the crown has been trepanned using a drill, the wedge is pressed under the crown so that the crown has to be detached from the tooth. The irregularly faceted surface design of the wedge allows different, appropriate forces and leverage to be achieved depending on the direction of the thrust. The shovel-like overall shape of the wedge creates a retention edge on the back, which can also be used to exert strong pulling forces on the crown.

Wird dieses Instrument mittels eines Ultraschallwellen erzeugenden Gerät in Schwingungen versetzt, die durch die starke Keilwirkung auf die Krone übertragen werden, so lösen sich auch Zementverbindungen durch Schwingung oder Klebeverbindungen durch Schwingung und Erwärmung.If this instrument is set into vibration by means of a device that generates ultrasonic waves, which are transmitted to the crown by the strong wedge effect, cement bonds are also loosened by vibration or adhesive bonds are loosened by vibration and heating.

Claims (3)

1. Werkzeug zum Entfernen von künstlichen Kronen von Zähnen:
Bestehend aus einem Stab, der an seinem angewinkeltem kurzen Ende einen schaufelförmigen Keil mit unregelmäßig mehrflächiger facettenartiger Oberfläche besitzt. 1. Tool for removing artificial crowns from teeth:
Consists of a rod which has a shovel-shaped wedge with an irregularly multi-faceted surface at its angled short end. 2. Werkzeug nach Anspruch 1, dadurch gekennzeichnet, daß der Keil breiter wie der Stab ist und dadurch Retentionskanten aufweist. 2. Tool according to claim 1, characterized in that the wedge is wider than the rod and therefore has retention edges. 3. Werkzeug nach Anspruch 1 und 2, dadurch gekennzeichnet, daß das Werkzeug mit Geräten, die Ultraschallwellen erzeugen verbunden werden kann. 3. Tool according to claim 1 and 2, characterized in that the tool can be connected to devices that generate ultrasonic waves.
