Digital Geometry Processing Applied in Customized Medical Implant Design

Standard medical implants are used in most implantation cases, but in some special cases, only those implants conforming to individual patient's skeletal morphology can serve the purpose. This paper proposes a new approach to design and fabricate customized exact-fit medical implants. With a real surgical case as the example, technical design details are presented; and two algorithms are given respectively for segmentation based on object features and triangular mesh defragmentation.
