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. |
