In complete arch implant rehabilitation, one of the greatest difficulties still encountered in the digital workflow is the deviation of the implant position during intraoral scanner (IOS) data acquisition. As a result, the passivity of a definitive prosthesis fabricated using IOS data might be compromised. Thus, an implant position verification method is essential, either digitally or conventionally executed. A fully digital protocol for the fabrication of the definitive fixed prosthesis for completely edentulous patients, without the interference of any conventional step within the digital process, is presented. For the verification of the captured position of the scan-bodies, novel scan analogs were connected to the interim prosthesis extraorally and scanned. The virtual superimposition of the interim prosthesis intraorally with the same prosthesis extraorally served as a verification device for the position of the implants.
在全牙弓种植修复中，数字工作流程仍面临的最大困难之一是在口内扫描仪（IOS）数据采集过程中种植体位置出现偏差。因此，使用IOS数据制作的最终修复体的被动就位可能会受到影响。所以，无论是通过数字方式还是传统方式执行，种植体位置验证方法都是必不可少的。本文介绍了一种用于为全口无牙患者制作最终固定修复体的全数字方案，该方案在数字流程中不受任何传统步骤的干扰。为了验证扫描体的捕获位置，将新型扫描代型在口外连接到临时修复体并进行扫描。口内临时修复体与口外同一修复体的虚拟叠加用作种植体位置的验证装置。
