KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung hat einen Spiralwurzelbohrer zum Gegenstande, bei welchem zum Unterschied von dem bekannten Pettee-Gleitbohrer der bohrende Teil nicht aus einem kantigen Draht, sondern aus einer, gegebenenfalls einen Bohrkopf tragenden, zylindrisch gewundenen Drahtspirale mit glatter' oder mit Feilenhieb versehener rauher Oberfläche besteht.The subject of the invention is a spiral root drill, in which the difference from the known Pettee sliding drill, the drilling part is not made from an angular wire, but from one, possibly one Cylindrical wound wire spiral carrying the drill head with a smooth 'or with a file cut provided rough surface.
Diese bohrende Spirale kann den Windungen der Zahnkanäle sehr leicht und,ohne zu brechen folgen, so daß ein Durchbohren der Wände der Zahnwurzel ausgeschlossen erscheint ; hingegen kann dieser Fall bei dem Pettee-Gleitbohrer sehr leicht eintreten, weilThis drilling spiral can make the turns of the tooth canals very easily and without too much break, so that drilling through the walls of the tooth root appears to be impossible ; on the other hand, this case can very easily occur with the Pettee sliding drill because

α bezeichnet den Bohrkopf, woran das Mittelstück b befestigt ist, das entweder in einem rosenknopfförmigen oder in einem anderen der bisher gebräuchlichen Endstücke c mit stumpfer, feiner Führungsspitze endet. α denotes the drill head to which the middle piece b is attached, which ends either in a rose button-shaped or in another of the previously common end pieces c with a blunt, fine guide tip.
Das Mittelstück b besteht aus einer weichen, leicht biegsamen, in ihrer Gesamtheit zylinderförmig enggewundenen Drahtspirale, die entweder eine glatte oder mit Feilenhieb versehene rauhe Oberfläche besitzt.The middle piece b consists of a soft, slightly flexible, in its entirety cylindrically tightly wound wire spiral, which has either a smooth surface or a rough surface provided with a file cut.
Bei Verwendung des Spiralwurzelbohrers folgt die Drahtspirale dem Orte des geringsten Widerstandes, d. i. dem Wurzelkariale mit seinen weichen Teilen, und bohrt sich nicht in das harte Zahnbein hinein.When using the spiral root drill, the wire spiral follows the location of the least Resistance, d. i. the root carial with its soft parts, and does not bore itself into the hard dentin.
Je nach der Weite des Wurzelkanales verwendet man zunächst eine feinere, dann event, zur Erweiterung des Wurzelkanales eine dickere Spirale. Dadurch wird die Entleerung eines Wurzelkanales schnell und mühelos gemacht und erfordert keine besondere Geschicklichkeit.Depending on the width of the root canal, first a finer one, then an event, a thick spiral to widen the root canal. This will drain a Root canal is done quickly and effortlessly and does not require any special skill.
