During intraoral complete-arch digital implant scanning, one of the most technique-sensitive steps is the implant data acquisition and merging of different surface geometry data sets for prototype prosthesis fabrication due to the absence of fixed landmarks. Recently developed extraoral techniques have allowed for an alternative approach for the digital acquisition of implant position in completely edentulous patients. Specifically, extraoral digital scanning of the conversion prosthesis after connecting reverse scan bodies has been proposed as an efficient approach. The reverse scan body protocol digitally simulates the traditional back-pouring technique long utilized in analog workflows. The present article describes a technique for simplifying the digital workflow for the fabrication of passive-fitting definitive prostheses using the reverse scan body concept.
在口腔内全牙弓数字化种植扫描过程中，由于缺乏固定的标记点，最具技术敏感性的步骤之一是种植体数据采集以及为制作原型修复体而合并不同的表面几何数据集。最近开发的口外技术为全口无牙患者的种植体位置数字化采集提供了另一种方法。具体而言，连接反向扫描体后对口外转换修复体进行数字化扫描已被提议作为一种有效的方法。反向扫描体方案以数字方式模拟了长期用于模拟工作流程的传统回灌技术。本文介绍了一种使用反向扫描体概念简化被动适配最终修复体制作数字工作流程的技术。
