A method for fabricating a custom cranial remodeling device for correction of cranial deformities in a subject is described. The method comprises generating a three-dimensional head data file for the subject. Predetermined reference points are identified on the head. The predetermined reference points are utilized to calculate contour lines on the head. A modified head shape data file is generated and juxtaposed with the head represented by the three-dimensional head data file having the contour lines thereon. The modified head shape data file is used to generate a shape for a desired custom cranial remodeling device, the shape having an interior surface to contact the head and an outer surface The contour lines establish peripheral edges for the custom cranial remodeling device.
