Automatic fabrication system for maxillofacial prosthesis

颌面部组织切除术后患者的功能和美观的恢复是非常重要的。面部假体是治疗这些患者最有效的技术。在面部假体的制造中，最微妙的护理是相对于修复的面部缺陷的三维形态定位眼球的位置。我们开发了一个导航系统来雕刻面部假体。该系统由一台个人电脑、一台投影仪和一个三脚架组成。将人脸照片输入计算机，在计算机中利用镜像技术生成人脸恢复图像。然后将修复后的图像投射到面部石膏模型上。通过最小的微调，可以雕刻出具有最佳眼睛位置和面部三维形态的面部假体。该导航系统对于制作精细的面部假体非常有用，并且能够减少使蜡模型适应患者的时间。导航系统发挥了它的作用。

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.
