1. A system for producing a custom cranial remodeling device to correct for a cranial shape abnormality of a subject, comprising: one or more processors; one or more memories; a first database comprising a first plurality of first three-dimensional digital data files captured directly from a corresponding plurality of subjects, each said first three-dimensional digital data file captured from an abnormally shaped head; a second database comprising a second plurality of second three-dimensional digital data files of modified head shapes each corresponding to one of said first database digital data files, each of said second three-dimensional digital data files being generated by said one or more processors operating on a corresponding first three-dimensional digital data files to produce a three-dimensional digital data file of a corrected head shape; a third database comprising a third plurality of three-dimensional digital data files generated by said one or more processors and each corresponding to three-dimensional trim lines for a corresponding cranial remodeling device of a first type provided for its corresponding second three-dimensional digital data file and either directly captured from said corresponding second cranial remodeling device or generated by said one or more processors; a fourth database comprising a fourth plurality of three-dimensional digital data files generated by said one or more processors and each corresponding to three-dimensional trim lines for a corresponding cranial remodeling device of a second type provided for its corresponding second three-dimensional digital data file and either directly captured from said corresponding second cranial remodeling device or generated by said one or more processors; and said one or more processors coupled to said first, second, third, and fourth databases; said one or more processors operable to receive a captured first three-dimensional digital data file of said subject; said one or more processors utilizing said captured first three-dimensional digital data file of said subject and said first and second databases to generate a new second three-dimensional digital data file of a modified head shape for said subject; said one or more processors utilizing said new second three-dimensional digital data file to control apparatus to control manufacture of said custom cranial remodeling device for said patient; and said one or more processors automatically utilizing said captured first three-dimensional digital data file of said subject to select one of said third and fourth databases to generate new trim lines for use in fabricating said custom cranial remodeling device; said one or more processors automatically processing said new trim lines based upon varied curvatures over the three-dimensional shape of said custom cranial remodeling device to calculate an offset for a cutting tool such that a cut made along said new trim lines by said cutting tool is perpendicular to a surface portion of said custom cranial remodeling device.
