Description

Beschreibung:Description:

In der Zahnmedizin werden zur Aufbereitung von Wurzelkanälen feine nadelartige Werkzeuge verwendet. Zur Füllung und Stabilisierung werden Wurzelstifte eingebracht. Sowohl die Aufbereitungsnadeln, wie auch die Wurzelstifte können bei Überlastung brechen und den Wurzelkanal obliterieren. Sinn der Erfindung ist es diese abgebrochenen Reste möglichst einfach zu entfernen.In dentistry, fine needle-like tools are used to prepare root canals. Root posts are inserted to fill and stabilize the canal. Both the preparation needles and the root posts can break if overloaded and obliterate the root canal. The purpose of the invention is to remove these broken-off remnants as easily as possible.

Dies geschieht mittels eines Stabes, der an seinem geraden oder angewinkeltem kurzen Ende eine U- oder V-förmige Kerbe besitzt. Nach der Anbringung einer oder zwei paralellen oder in spitzen Winkel aufeinander zulaufenden Retentionsnuten unter dem oberen Ende des zu entfernenden Fragmentes wird die V-förmige Kerbe über diese Retentionsnuten geschoben, so daß eine starke Klemm- und Hebelwirkung entsteht, und durch diese Friktion und Retention der frakturierte Rest, falls nötig zusätzlich durch Rotation, gelöst und aus dem Wurzelkanal gezogen werden kann.This is done using a rod that has a U- or V-shaped notch on its straight or angled short end. After one or two parallel or acutely angled retention grooves have been made under the upper end of the fragment to be removed, the V-shaped notch is pushed over these retention grooves so that a strong clamping and lever effect is created, and through this friction and retention the fractured remainder can be loosened and pulled out of the root canal, if necessary additionally by rotation.

Wird dieses Instrument mittels eines Ultraschallwellen erzeugenden Gerät in Schwingungen versetzt, die durch die starke Klemmwirkung des U- oder V-förmigenAnsatzes auf das Fragment übertragen werden, so lösen sich schnellstens 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 fragment by the strong clamping effect of the U- or V-shaped attachment, cement bonds will also dissolve very quickly due to vibration or adhesive bonds due to vibration and heating.
