Abstract
The matter that requires the most delicate care in the fabrication of an orbital prosthesis is where to locate the eye ball relative to the restored 3-dimensional morphology of the facial defect. We developed a navigation system for the sculpting of a facial prosthesis. The system consists of a personal computer, a projector and a tripod. The facial photograph is input into the computer, and the restored image of the face is generated by using the mirror image technique in the computer. This restored image is then projected onto a facial plaster model. With a minimum of fine tuning, a facial prosthesis can be sculpted with optimal eye position and 3-dimensional morphology of the face. The navigation system is very useful for fabricating fine facial prostheses and reduce the time taken to adapt the wax model to the patient. The navigation system has proved its usefulness.
