| Abstract: | The current simulation planning systems for maxillofacial prosthesis surgery were used to extrapolate 3D surgical movements and outcomes based on the 2D radiographs, which were inadequate for complex surgical movements.A 3D treatment planning system based on the computerized tomography (CT) data was presented. A 3D data field was constructed out of the sectional image stack through linear interpolation. After objective tissue segmentation and using the marching cubes algorithm method, the triangular mesh model and 3D geometric model of diseased facial skeleton were reconstructed. Then the model was cut, the segments were moved or rotated to their predicted positions, and angles and distances were measured. After triangular mesh model was decimated, a RP model was manufactured for surgical simulation and prosthesis design. The system was used in clinic with more than fifty cases and technically validated with success. |
