根据头颅模型进行手术模拟设计以及个性化修复体的制作是数字化外科技术的核心部分。由于颅颌面部骨骼解剖关系的复杂性,传统诊疗方法不能准确再现颅颌面部畸形的特点,更无法进行术前手术模拟。数字化模型外科是近年来基于三维重建技术、计算机辅助设计技术、快速成型技术和反求工程技术发展而来 The modeling of the surgical simulation based on the skull model and the fabrication of a personalized restoration are central to the digital surgical technique. Due to the complexity of craniofacial bone anatomy, the traditional diagnosis and treatment methods can not accurately reproduce the characteristics of craniomaxillofacial deformity, but also can not be preoperative surgical simulation. Digital model surgery in recent years based on the three-dimensional reconstruction technology, computer-aided design, rapid prototyping and reverse engineering technology
