Method and device for placing dental implants

The invention relates to a method and device for placing implants (1) using a surgical template (11) which is made from tomographic cuts in the patient's jawbone (7). According to the invention, step drills (4) and calibrating drills (5), having a single standard diameter for each type of implant (1), are guided through drill bushings (18) which are inserted into bores (15) in the template (11) in order to produce any drilling sequence corresponding to an implant plan. The penetration depth of the drills (4, 5) is controlled by the height of the bores (15) or by the drill rings (21). The aforementioned template (11) bores (15) serve as a guide for the precise placement of the implants (1) owing to the adapted implant supports (3). Moreover, washers (23), which are mounted around the implant supports (3), limit compression in relation to the implants (1) while said implants are being placed (20). The above-mentioned characteristics serve to limit the required number of drills (4, 5) and implant supports (3) to the longest models only. The inventive method and device are particularly suitable for computer-assisted implantology systems.
