Abstract: The invention relates to a dental implantology device combining a specific drill (21) which is adapted to jawbone density variations and an implant (1) which is formed in a corresponding manner to the drill (21) and which is also adapted to bone density variations. According to the invention, the implant (1) and the drill (2) comprise a plurality of zones over the heights thereof, which are suitably produced such that the drill (21) alone is used to form the seat for the implant (1). The invention is suitable for high-precision dental implantology.
