Die Erfindung betrifft einen Bohrer als Implantatwerkzeug zum Einbringen von Bohrungen im Kiefer mit einem konisch geformten Arbeitsteil, dessen Schneiden schraubenförmig und rechtsschneidend sind.The invention relates to a drill as an implant tool for making holes in the jaw with a conically shaped working part whose cutting edges are helical and right-hand cutting.
Um Zahnimplantate in. einem Kieferknochen zu befestigen, ist es bekannt, Passbohrungen durch einen Bohrer einzufrasen, die ein konisch geformtes Arbeitsteil besitzen. Hierbei ist es auch bekannt, die Schneiden des Arbeitsteils schraubenförmig und rechtsschneidend auszuführen, wobei die Schneiden einen Rechtsdrall haben. Es hat sich gezeigt, dass diese bekannten Bohrer beim axialen Einsatz rattern und schlagen.In order to fix dental implants in a jawbone, it is known to mill fitting holes using a drill that has a conical working part. It is also known to make the cutting edges of the working part helical and right-hand cutting, with the cutting edges having a right-hand twist. It has been shown that these known drills rattle and knock when used axially.
Aufgabe der Erfindung ist es, einen Bohrer der eingangs genannten Art so zu verbessern, dass ein ruhiger Bohrprozess ermöglicht wird.The object of the invention is to improve a drill of the type mentioned above so that a smooth drilling process is possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Schneiden einen Linksdrall haben, indem von dem Schaft aus gesehen die schraubenförmigen Schneiden sich entgegen dem Uhrzeigersinn zur vorderen Spitze hin drehen.This object is achieved according to the invention in that the cutting edges have a left-hand twist, in that, viewed from the shaft, the helical cutting edges rotate anti-clockwise towards the front tip.
Ein solcher Bohrer mit Linksdrall verhindert beim axialen Einsatz ein Rattern und Schlagen, so dass das Bohren ruhig und besonders exakt erfolgt, und damit präzise Passbohrungen ermöglicht werden. Auch haben solche Werkzeuge eine hohe Lebensdauer und eine geringe Wärmeentwicklung.Such a drill with a left-hand twist prevents chattering and impact during axial use, so that drilling is smooth and particularly precise, thus enabling precise fitting holes. Such tools also have a long service life and generate little heat.
Besonders vorteilhaft ist es, wenn die vordere Bohrerspitze abgerundet ist und im axialen Längsschnitt teilkreisförmig oder teilovalförmig insbesondere teilellipsenförmig ist. Auch wird zur besseren Wärmeabfuhr vorgeschlagen, dass der Arbeitsbereich einen inneren wassergekühlten Hohlraum aufweist.It is particularly advantageous if the front drill tip is rounded and is partially circular or partially oval, particularly partially elliptical, in the axial longitudinal section. It is also proposed that the working area has an internal water-cooled cavity for better heat dissipation.
Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zeigenTwo embodiments of the invention are shown in the drawing and are described in more detail below. They show
Fig. 1 eine Seitenansicht eines ersten Bohrers und Fig. 2 eine Seitenansicht eines zweiten Bohrers.Fig. 1 is a side view of a first drill and Fig. 2 is a side view of a second drill.
Der Bohrer 1 weist einen Arbeitsteil 2 und einen daran koaxial anschließenden Schaft 3 zum Einspannen des Bohrers auf. Der Arbeitsteil besitzt über seine Länge verlaufende Schneiden 4 auf, deren Anzahl verschieden sein kann und die vom Schaft 3 aus gesehen sich schraubenförmig entgegen dem Uhrzeigersinn zur vorderen Spitze bzw. vorderen Ende 5 hin drehen, so dass die Schneiden einen Linksdrall haben.The drill 1 has a working part 2 and a shaft 3 coaxially connected to it for clamping the drill. The working part has cutting edges 4 running along its length, the number of which can vary and which, viewed from the shaft 3, rotate in a helical anti-clockwise direction towards the front tip or front end 5, so that the cutting edges have a left-hand twist.
Der Arbeitsteil 2 ist konisch geformt, das heißt er verjüngt sich zur vorderen Spitze 5 hin und die vordere Spitze 5 ist abgerundet, das heißt sie ist im Ausführungsbeispiel nach Fig. 1 kugelabschnittförmig, so dass sie im axialen Längsschnitt teil kreisförmig ist. Stattdessen kann aber auch die Form gerundet und abweichend von einem Kugelabschnitt sein, so dass der axiale Längsschnitt teilovalförmig insbesondere teilellipsenförmig ist.The working part 2 is conical in shape, i.e. it tapers towards the front tip 5 and the front tip 5 is rounded, i.e. in the embodiment according to Fig. 1 it is shaped like a spherical segment, so that it is partially circular in the axial longitudinal section. Instead, however, the shape can also be rounded and deviate from a spherical segment, so that the axial longitudinal section is partially oval, in particular partially elliptical.
Der Arbeitsbereich weist einen inneren axialen wassergekühlten Hohlraum auf, so dass entstehende Wärme sicher abgeführt wird.The working area has an internal axial water-cooled cavity so that any heat generated is safely dissipated.
Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 dadurch, dass zum einen eine größere Anzahl von Schneiden vorgesehen ist und der Arbeitsteil 2 länger und schlanker ausgeführt ist, das heißt der kegelabschnittförmige Arbeitsteil 2 weist in seinen Bereichen einen geringeren Durchmesser auf als bei der ersten Ausführungsform.The embodiment according to Fig. 2 differs from that according to Fig. 1 in that, on the one hand, a larger number of cutting edges is provided and the working part 2 is longer and slimmer, i.e. the conical section-shaped working part 2 has a smaller diameter in its regions than in the first embodiment.
