The traditional protocol for guided surgery in a completely edentulous patient is time-consuming, requiring the fabrication of a radiographic guide and a dual cone beam computed tomography (CBCT) scan. Using intraoral scanners to scan the edentulous ridge and the existing denture has been advocated to simplify the process. This technique offers a versatile, precise, and predictable method for the digital planning workflow in edentulous patients for either a fixed or removable restoration. In addition, this approach can help improve the quality of the guide produced by reducing CBCT artifacts associated with the existing denture, as well as capture the soft-tissue contour to further improve the fit of the surgical guide.

在完全缺牙的患者中进行常规引导手术的协议非常耗时，需要制作放射线引导器和双锥束计算机断层扫描（CBCT）扫描。有人提倡使用口内扫描仪扫描无牙和现有的义齿，以简化该过程。该技术为无牙颌患者的固定或可移动修复体的数字计划工作流程提供了一种通用，精确且可预测的方法。另外，该方法可通过减少与现有义齿相关的CBCT伪影来帮助提高导向器的质量，并捕获软组织轮廓以进一步改善手术导向器的贴合性。
