The objective of the present report is to illustrate a proof-of-concept protocol for CAD/CAM fabrication of milled verification jigs during full-arch implant rehabilitation using photogrammetry for data acquisition. The present report aims to bridge the gap between analog and digital workflows by introducing a CAD/CAM technique to intraorally verify digitally acquired information without the use of the technique-sensitive and labor-intensive conventional resin verification jig. One patient was treated with a digital prosthodontic protocol where a digitally designed CAD/CAM milled verification jig (generated from intraoral digital scans) was used to confirm implant 3D positioning prior to the fabrication of double full-arch monolithic definitive zirconia prostheses. The procedures are presented step-by-step after clinical and radiographic observation.
本报告的目的是说明在全口种植体修复中使用摄影测量术进行数据采集时，通过 CAD/CAM 制造铣削验证夹具的概念验证方案。本报告旨在通过引入 CAD/CAM 技术来在口腔内验证数字获取的信息，而无需使用技术敏感且劳动密集型的传统树脂验证夹具，从而在模拟和数字工作流程之间架起桥梁。一名患者接受了数字化修复治疗方案，其中使用数字化设计的 CAD/CAM 铣削验证夹具（由口腔内数字扫描生成）来确认种植体的三维定位，然后再制作双全口整体式氧化锆固定修复体。在临床和影像学观察后，按步骤介绍了这些程序。
