PROCEDE POUR LA FABRICATION D'UN CHAPEAU D'UN DISPOSITIF DE RECOUVREMENT POUR UN SITE DE DEFAUT OSSEUX, ET DISPOSITIF POUR LE RECOUVREMENT ET/OU LA RECONSTRUCTION D'UN SITE DE DEFAUT OSSEUX
A method for producing an attachment piece (4), which has at least one predetermined break point (16), a cover device for a bone defect site (2), and a device (1) for covering and/or reconstructing a bone defect site (2) are proposed, wherein by comparing a first data set, which represents the affected bone defect site (2) in the actual state, against a second data set, which represents the desired state of a bone regenerated at the bone defect site (2), wherein the second data set was calculated or was recorded at a time when the bone at the site now to be regenerated was still a healthy bone (18), it is possible that the regenerated bone, which arises through the regeneration of the bone defect site (2), has a form corresponding to the form that the bone at the site to be regenerated had when it was still healthy.
