Definitions
- the present invention relates to a pilot drill, a step drill and a drill set formed therefrom for use in dental implantology.
- the pilot drill is used to produce a blind hole-shaped pilot hole to be inserted into a human jawbone as preparation for its enlargement to a step hole, which is done with one or - with a further enlargement of the step hole - several different step drills.
- the prepared stepped bore is intended for receiving a dental implant, preferably in the form of a screw.
- the prepared borehole can be provided with an internal thread before application or the implant is self-tapping, as a result of which the internal thread is cut when the implant is screwed into the jawbone.
- the present invention relates primarily to dental implants in screw form.
- the healed implant forms the anchor for a superstructure to be built.
- a drill set is shown that consists of a round bur and three twist drills with increasing cross-sections.
- the round bur is used to mark the position on the cortex where the hole is to be made.
- the cortex and cancellous bone are drilled out almost seamlessly with the first twist drill.
- Wieland Dental +technik GmbH & Co. KG, D-75179 Pforzheim, Germany offers a drill sequence for a self-cutting screw implant with 03.3mm and conical neck, consisting of the following drilling instruments: a) an initial drill for precise drilling of the position; b) a drill bit 01.8mm for the preparation of the hole in full depth; c) a step drill 01.8mm / 02.5mm to widen the bore mouth to 02.5mm; d) a drill bit 02.5mm to widen the hole over the entire depth to 02.5mm; and e) a conical drill with a guide 02.5mm to widen the bore mouth.
- Implant Innovation Inc. USA, offers a drill set where, even before the next larger drill is used, the existing hole is widened to the next higher diameter over a short mouth area to ensure that the subsequent drill is well centered. Step drills are used for this. These step drills have a round apical nose with the diameter of the preceding drill, which causes centering in the hole and has no cutting function. This system requires a step drill and the corresponding twist drill for each drilling diameter, so that a larger number of drilling instruments and operations are also required here.
- a drill sequence from FRIADENT GmbH, D-68229 Mannheim, Germany is known.
- the following drills are used for a self-tapping 3-stage screw implant 05.5mm: a) a pre-drill 02.0mm for precise drilling of the position and specification of the axial direction; b) a rose drill 03.4mm to widen the bore mouth to 03.4mm; c) a 3-step milling cutter for the preparation of a 3-step hole 03.4mm; d) a 3-step milling cutter for preparing a 03.8mm hole; e) a 3-step milling cutter for preparing a 04.5mm hole; and f) a 3-step milling cutter for preparing a 05.5mm hole.
- the task is based on creating an improved pilot drill.
- Another task is to create an improved tiered borer.
- An additional task is to propose a multi-part, advantageously usable drill set from the pilot and step drills. It can be assumed here that the drilled hole penetrates the cortical bone very precisely at the planning-appropriate location in order to ensure the correct position of the implant and thus of the subsequent denture. The direction of the bore must be precisely aligned in order to optimally absorb the loads that will later affect the dentures.
- the jawbone should be stressed as little as possible.
- the preparation of the bore must be simple and time-saving in just a few simple steps; only a small number of instruments should be required. Finally, it is important to keep the overall costs low.

- the pilot guide with the pilot tip is intended to determine the position of the stepped bore to be produced by introducing a pilot hole approach through the cortex of the jawbone, the approach consisting of a pilot hole guide and a pilot hole tip.
- the step is designed to generate a noticeably increased drilling resistance after the penetrated cortex - with the completion of the pilot drill guide and tip - so that the surgeon can check the direction of the drill at this indication.

It can be seen that around the pilot hole 61 - with the pilot hole tip 610, the pilot hole guide 611 and the pilot hole neck 612 - all further step holes 62, 63, 64 made afterwards - with the corresponding step tips 620, 630, 640, the associated step guides 621, 631, 641 and step necks 622,632,642 - are centered and have the same drilling depth.
- the diameter b2 on the drill neck 12 of the pilot drill 1 is at least almost identical to the diameter b2 'on the step guide 21 of the first step drill 2.
- at least almost identical diameters also result in the resulting bores, namely the pilot drill neck 612 and the first step guide 621, which both are labeled d2.
- the bore diameter d1 was produced by the pilot guide 11 of the pilot drill 1 with the bore diameter b1.
- the bore diameters d3 and d4 originate from the at least almost identical diameters b3 on the drill neck 12 of the first step drill 2 and the diameter b3 'on the step guide 21 of the second step drill 2 or of the diameters b4 on the drill neck 12 of the second step drill 2 and the diameter b4 'on the step guide 21 of the third step drill 2.
- This facilitates the insertion and penetration of the outside non-cutting step guide 21 with the blunt guide cutting edges 212 into the pilot neck 612 of the pilot bore 61 or into the step neck 622, 622 of the first or second step bore 62, 63.
- FIG. 14C shows in principle how the tip 41 of the implant 4 with the largest diameter i5 lies in the cross section of the third stepped bore 64 with diameter d5.
- the rounding 411 from the implant tip 41 fits well into the step tip 640 of the third step bore 64.
- the cross section of the step guide 641 of the local step bore 64 is minimally smaller than the cross section of the cone 412 of the implant tip 41.
- it has a cutting edge geometry 44 with a cone cutting area 441. As a result, particles are cut off from the bone 5 in the region of the cone 412 and the bore cross section is expanded accordingly.
