Method of manufacture of custom cranial remodeling devices by additive manufacturing
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 and determining contour lines on the head. The method further comprises automatically generating a modified head shape data file and juxtaposing the modified head shape with the head represented by the three-dimensional head data file having the contour lines thereon. Still further the method includes utilizing the modified head shape data file 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 method also includes projecting lines outward from the contour lines to the outer surface and utilizing the projected lines to establish cranial remodeling device contour lines for the custom cranial remodeling device.
1. A method for fabricating a custom cranial remodeling device for correction of cranial deformities in a subject's head, said method comprising:
providing a processor, said processor operating on a three-dimensional head data file for a head shape of said subject's head to identify and utilize predetermined reference points on said head shape represented by data in said three-dimensional head data file to determine one or more contour lines on said head shape represented by said three-dimensional head data file, said contour lines defining peripheral edges of said custom cranial remodeling device;
operating said processor to automatically to process said head data file to produce a modified head shape data file for said head;
operating said processor to utilize said modified head shape data file to generate a device shape for a said custom cranial remodeling device, said device shape having an interior surface to contact said head and an outer surface;
