3D打印技术在颅颌面创伤应用的相关技 术与发展趋势 张纯妍 聂鑫 沈阳联保中心大连疗养院口腔科 温州医科大学附属 口腔医院颌面外科 摘 要: 3D打印作为新兴技术首次应用于工业领域, 目前在医疗领域的潜在价值也受到 诸多关注。 自从20世纪 80年代后期引入医学领域以来, 利用这一技术, 医学数 字成像和通信 (DICOM) 文件可以转化为立体光刻 (STL) 文件, 打印出血管、 肿 瘤和头盖骨等三维解剖结构, 使外科医生能够改进术前规划。 由于该领域起步晚, 技术种类繁多且各有利弊, 目前尚无标准的 3D打印模式用于临床和医学研究。 为了使创伤外科临床医生能正确使用3D打印技术, 笔者对各种3D打印和计算机 辅助设计 (CAD) 软件的临床应用特别是颅颌面创伤的应用作一综述。 关键词: 颅颌面; 创伤; 3D 打印; 计算机辅助; Three-dimensional printing: applied technologies and developmental trend in craniofacial trauma ZHANG Chun-yan NIE Xin Department of Stomatology, Dalian Sanatorium , Shenyang Joint Logistics Center; Department of Maxillofacial Surgery, Stomatological Hospital, Wenzhou Medical University; Abstract: Three-dimensional ( 3 D) printing is a developing technology and firstly used in the industrial field. Recently, it gains a lot of attention in the medical field for its potential benefits. Since its introduction to the medical field in the late 1980 s, with the 3 D printing technology, digital imaging and communication in medicine ( DICOM) can be translated into stereo lithography ( STL) files. Finally, 3 D anatomical structures such as vessels, tumors, and skulls are printed, which enable surgeons to improve pre-operative planning. Due to the infancy of the field, and a wide range of technologies with varying advantages and disadvantages, there is currently no standard 3 D printing process for clinical and medical research. To enable craniofacial trauma doctor to optimize the use of this technology, we outline the variable clinical practical methods and design software for 3 D printing under the assistance of computer in the surgical field, especially in the field of craniofacial trauma. Keyword: craniofacial surgery; trauma; three-dimensional printing; computer-aided design; 3D打印技术是近年快速发展的新兴技术, 其基本原理是根据计算机辅助设计 (computeraided design, CAD) 模型或X射线计算机断层成像 (X-ray computed tomography, CT) 形成的数据, 在电脑程序控制下, 基于离散和堆积成型的原 理, 利用光、热等外界输入, 并配合打印材料的特性, 将打印材料逐步固化、堆 积成型, 实
