Abstract:
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.
