Abstract： |
The preparation method of biological material integrally-implanted ear soft bone bionic support includes the following steps: 1. preparing laminate image of reference auricle contour; 2. restructuring said image to obtain three-D entity model; 3. layering said three-D entity model to obtain two-D graph of every layer; 4. coding every layer two-D graph to obtain digital control code; 5. inputting digital control code of every layer two-D graph into quick forming machine; and 6. using the quick forming machine to make hierarchical piling and hierrarchical cutting according to the inputted digital control codes so as to obtain the invented ear soft bone support. |
