It is important for the patients after resection of the maxillofacial tissues to recover function and esthetics. The facial prosthesis is the most effective excellent technique for these patients. The most delicate care in the fabrication of a facial 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 on to 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 able to reduce the time taken to adapt the wax model to the patient. The navigation system has provided its usefulness.
