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.

A surgical template for performing dental implant osteotomies comprises a malleable, resinous, thermoplastic base, at least one non-thermoplastic, rigid drill guide attached to the base, and a securing mechanism between the base and the drill guide. The template may reversibly melt to a malleable state and can be handled by hand without additional tools so as to conform to the adjacent teeth of the edentulous ridge, either directly in the patient's mouth or on a cast model. Dental osteotomies using the template can then be performed. The surgical template may be manufactured of a thermoplastic material having a sharp and low melting point but high rigidity in the solid state at room temperature.

A dental drilling assembly comprises a drill (30) and a bushing (40) which is mounted, or mountable, coaxially with the drill (30). The bushing (40) can be inserted with the drill (30) into a bore hole of a surgical template and can similarly be removed from the bore hole when a hole has been drilled. The bushing has a serrated leading edge (51) for cutting soft gingival tissue. A pathway (54, 55) is defined between the drill (30) and the bushing (40). The pathway (54, 55) cooperates with a fluted channel on the drill and serves, in use, to evacuate soft tissue from the cutting surface (51). A surgical template has at least one bore hole representing a position where the drill is required to be used. The bore hole, or a bore tube lining the bore hole, has a diameter which is only slightly larger than the bushing.

A technique for generating a data set that geometrically defines a bone cut configuration for transverse maxillary distraction is using a computer-implemented method. An aspect of the technique comprises creating a numeric model of a maxilla based on patient-specific data of the maxilla. The numeric model is representative of mechanical properties of the maxilla. Based on the numeric model thus generated, one or more cut configurations for one or more bone cuts on at least one of a left hand side and a right hand side of the maxilla are determined. Each cut configuration has been determined to compensate for asymmetric mechanical properties of the maxilla. In a further step, a data set indicative of the one or more cut configurations thus determined is generated. The data set may be used to create a surgical template or jig, for computer-assisted surgery or a surgical navigation system.
