Automated generation of bone treatment means

The invention relates to a method (1) for producing bone treatment means (7), with a first step (2) in which original 3D data of a bone (8) or of a bone portion of a specific patient to be treated are made available, wherein a site to be treated is present inside the bone (8) or the bone portion, with a second step (3) involving the use of 3D data of a reference patient who has been selected according to predefined criteria, wherein the 3D data correspond to the bone (8) or to the bone portion with the site to be treated, and with a third and reconstructive step (4) for supplementing 3D data for the reconstruction of the site to be treated, wherein a mirroring step (5) is used in which 3D data of the specific patient to be treated, which have their origin on a mirror-symmetrical other side of the patient, are superposed, specifically at a site corresponding to the bone (8) or bone portion, in order to obtain the combined 3D data.
