Patent ID: 8720037

Claim:
A method for making a guide channel in a drilling jig for drilling a dental implant jaw bore to be bored into a patient's jaw bone to a target depth (L 1 ) using a jaw drill with a drill stop, the method comprising: step 1 providing an auxiliary jig comprising a coupling structure which corresponds to a corresponding coupling structure of the drilling jig so that the auxiliary jig and the drilling jig are arranged in a defined spatial position relative to each other; step 2 drilling an auxiliary bore into the auxiliary jig so as to be in a virtual axial alignment with the planned dental implant jaw bore; step 3 inserting an auxiliary bore sleeve comprising a reference ring plane into the auxiliary bore in an axial position predefined by the target depth (L 1 ) of the planned jaw dental implant jaw bore; step 4 placing the auxiliary jig on the drilling jig in the spatial position defined by the coupling structure and the corresponding coupling structure; step 5 drilling a guide bore into the drilling jig so as to be in axial alignment with the auxiliary bore sleeve; step 6 inserting a guide sleeve into the guide bore using a positioning tool comprising a reference device so as to form the guide channel, the guide sleeve comprising a depth stop for the drill stop, the guide sleeve being inserted to an insertion depth defined by the reference ring plane and the reference device; and step 7 removing the auxiliary jig, wherein, steps 1-7 are performed in the order set forth.
