本研究描述了术前定制植入物的设计和制造。植入物形状和功能要求通过基于CT扫描和镜像操作的数字数据确定。介绍了定制下颌骨修复体的设计过程、制造工艺（直接金属激光烧结）和尺寸控制。报道了钛合金（Ti-6Al-4V）中具有复杂几何形状和内部结构的定制植入物的激光烧结工艺及其限制。还描述了复杂零件生产中的重要参数和限制，包括支撑结构、最大悬伸角度和内部结构。(C)2010爱思唯尔有限公司版权所有。
Design and manufacturing of customized implants prior to surgery are described in this study. Implant shape and functional requirements are established by digital data based on CT scans and mirroring operations. The design process of customized mandible prosthesis is illustrated as well as its manufacturing process (direct metal laser sintering) and dimensional control. Laser sintering process and its constraints for the production of customized implants in titanium alloy (Ti-6Al-4V) with complex geometry and internal structures are reported. Important parameters and restrictions in the production of complex parts, including support structures, maximum overhanging angle and internal structure are also described. (C) 2010 Elsevier Ltd.
