In order to incorporate a dental implant, it is necessary to create an implant bed, which is done using a set of drills with marking, pilot and, for example, so-called cannon drills, possibly with subsequent thread cutting using a corresponding thread cutter or using a self-tapping implant itself, which in this combination applies to round implants, while a disc cutter was used for blade implants, which sacrificed massive and unnecessary bone substance.

For this reason, the applicant has recently submitted an application with the title "oscillating saw".

For a newly registered step implant, if the insertion instruments described above are retained, a new set of drills is required, which allows the optimally coordinated implant bed to be created for the individually completed step implant.

As usual, this requires a marking drill and a pilot drill with length marking, preferably with internal cooling.

The maximum drilling depth is achieved by a length-marked, internally cooled drill bit that is shaped similarly to a cannon drill or corresponds to a twist drill with its corresponding cutting edges.

For the second stage, a drill is used whose distal part is preferably designed as a guide, with a diameter in this area corresponding to the most caudal (lowest) hole and, from a defined length, widening to become a drill that is preferably internally cooled, whereby a twist drill with its chip removal is most likely to be preferred to a cannon drill. The drilling part also has a length marking in order to create an appropriate bed for the implant step attachment.

For all other drills, the end part, manufactured in a rotary manner, corresponds to a guide and the following part, as a preferred internally cooled drill, is adapted to the respective implant step attachment as a twist drill.

In practical application, after using the marking and pilot drill, the first implant bed-creating drill is used, which has an internally cooled length marking and its diameter corresponds to that of the lowest part of the implant. The drilling depth was previously determined and an implant body was completed according to the expected bone situation.

For the first implant level, a drill is used whose lower part is designed to be circular and thus has guiding flexibility, while the diameter is matched to the lowest implant level.

In the following drill, these can be seen with both the guide and drilling parts, so that the guide part is also designed in a stepped, rotating shape. The length markings are used to identify the penetration depth according to the implant step that has been placed.

The invention will now be explained in more detail with reference to claims 1 - 5 and figures 1, 2.

It shows:

Figure 1 shows a possible step implant,

Figure 2 schematically shows a possible embodiment of a drill to create an optimal
Step implant bed, shown on a
Implant level.

Figure 1 shows a schematic of a possible step implant (1) with its indicated "soul" (2), onto which (2) the individual implant steps (3) are preferably screwed. The implant body is assembled according to the determined bone conditions and is ready for implantation. The implant (1) is closed in the healing phase (13).

Figure 2 shows a schematic of a possible drill example (4) for the third implant step of the end part (5), whereby the guides (6,7) for the implant steps (3) and (3 ^λ ) are designed to be circular and whereby the actual drill part (8) with its indicated secondary cutting edges (9) and the main cutting edges not indicated here in the diagram has a through perforation (10) for internal cooling, which of course also continues into the receiving extension (12) for e.g. a surgical angle piece. In addition, the drill part (8) has length markings (11) which are necessary to optimize the implant bed for the inserted step extension (3).
