摘要： The invention pertains to a process for producing endoprostheses wherein the data block of a three-dimensional actual model (10) of the existing bone structure of a patient is acquired using CT scanning; in a computer the actual model (10) thus determined is subtracted from the data block of an existing or CT scan-generated three-dimensional command model (14), and from the difference a computer-internal model for the endoprosthesis is formed. With this process, to reduce the work required for making the corrective adaptation of the endoprosthesis and to avoid faulty adaptations, the invention proposes that the data blocks of the actual model (10) and reference model (14) are converted into the data of a CAD free form surface geometry describing the limiting surfaces of the models through spline and Bézier functions oriented to points of support and are imaged, superimposed, on the computer monitor, and that this imaging is used to take back segments of the interface (11) of the actual model (10) by displacing points of support toward the volume of the command model (14).
