This article describes a technique to make an implant-retained maxillofacial prosthesis using CAD/CAM technology and a rapid prototyping machine. The primary advantage of this technique is virtual 3-dimensional integration of the defective surface with the mirrored and digitalized normal ear. Making an impression of the defective side is not necessary, because only the position of the implants must be recorded to develop the bar for the retention of the prosthesis. This procedure allows positioning of the ear straight onto the computer screen, eliminating the diagnostic waxing, and the fabrication of the stone mold is not necessary because of the rapid prototyping process.
本文介绍了一种使用CAD/CAM技术和快速成型机制作种植体固位式颌面修复体的技术。该技术的主要优点是将缺损表面与镜像数字化的正常耳朵进行虚拟三维整合。由于制作修复体固位杆时仅需记录种植体的位置，因此无需对缺损侧取印模。此操作可将耳朵直接定位在电脑屏幕上，无需制作诊断蜡型，且由于采用了快速成型工艺，无需制作石膏模型。
