With the advent of CAD/CAM and rapid prototyping (RP), a technical revolution in oral and maxillofacial trauma was promoted to benefit treatment, repair of maxillofacial fractures and reconstruction of maxillofacial defects.
For a patient with zygomatico-facial collapse deformity resulting from a zygomatico-orbito-maxillary complex (ZOMC) fracture, CT scan data were processed by using Mimics 10.0 for three-dimensional (3D) reconstruction. The reduction design was aided by 3D virtual imaging and the 3D skull model was reproduced using the RP technique. In line with the design by Mimics, presurgery was performed on the 3D skull model and the semi-coronal incision was taken for reduction of ZOMC fracture, based on the outcome from the presurgery.
Postoperative CT and images revealed significantly modified zygomatic collapse and zygomatic arch rise and well-modified facial symmetry.
The CAD/CAM and RP technique is a relatively useful tool that can assist surgeons with reconstruction of the maxillofacial skeleton, especially in repairs of ZOMC fracture.
随着计算机辅助设计/计算机辅助制造（CAD/CAM）和快速成型（RP）技术的出现，口腔颌面创伤领域迎来了一场技术革命，这有利于颌面部骨折的治疗、修复以及颌面部缺损的重建。
对于一名因颧眶上颌复合体（ZOMC）骨折导致颧面部塌陷畸形的患者，利用Mimics 10.0软件处理CT扫描数据以进行三维（3D）重建。借助3D虚拟成像辅助进行复位设计，并使用RP技术复制3D颅骨模型。根据Mimics的设计，在3D颅骨模型上进行术前操作，并根据术前结果采用半冠状切口进行ZOMC骨折复位。
术后CT及影像显示，颧部塌陷明显改善，颧弓升高，面部对称性良好。
CAD/CAM和RP技术是一种相对有用的工具，可协助外科医生进行颌面骨骼重建，尤其是在ZOMC骨折的修复中。
