| Abstract: | Based on patient forehead CT data,the 3-D model of a damaged skull is reconstructed by using the method of reverse engineering,the skull-restoration of titanium plate is digitally designed.The result of the virtual assembly shows that the damaged skull and the restoration are well fitted.The strength analysis of the titanium restoration is conducted by using finite element method,indicating that it has enough mechanical strength,which provides the reliable foundation for the next step digitized manufacture. |
