Title (EN) METHOD AND DRILL BIT FOR EXTRACTING A ROOT OF A TOOTH
(FR) METHODE ET FORET POUR EXTRAIRE UNE RACINE DENTAIRE
(DE) VERFAHREN UND BOHRER ZUR EXTRAKTION EINER ZAHNWURZEL
Abstract:
(EN) In order to extract a root of a tooth, this root (12) is drilled by a pin projection (8), which has a smaller diameter and is coated with an abrasive material. Afterwards, a threaded pin is inserted by rotation into the opening in the tooth made by the pin projection. As a result, the threaded pin whose upper part is provided with a lug is sufficiently anchored whereby enabling an extraction in the longitudinal direction of the tooth to be reliably carried out.
(FR) Selon l'invention, pour extraire une racine dentaire, ladite racine dentaire (12) est alésée à l'aide d'une broche saillante (8) de diamètre inférieur, recouverte d'un matériau abrasif. Une broche filetée est ensuite introduite par rotation dans l'ouverture dentaire ainsi préparée, ce qui a pour effet que la broche filetée munie d'un oeillet est suffisamment ancrée pour permettre de procéder à une extraction de manière fiable dans le sens longitudinal de la dent.
(DE) Zur Extraktion einer Zahnwurzel wird diese Zahnwurzel (12) durch einen mit abrasivem Material beschichteten, im Durchmesser geringeren Stiftan­satz (8) aufgebohrt. Hernach wird ein Gewindestift in die so vorbereitete Zahnöffnung eingedreht. Dadurch ist der oben mit einer Oese versehene Gewindestift so ausreichend verankert, dass in zuverlässiger Weise eine Extraktion in Zahnlängsrichtung ausgeführt werden kann.
