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.
在全口无牙患者中，传统的引导手术方案耗时较长，需要制作放射影像导板和双锥形束 CT（CBCT）扫描。使用口内扫描仪扫描无牙颌牙槽嵴和现有义齿已被提倡用于简化该过程。该技术为无牙患者的固定或可摘修复体的数字化规划工作流程提供了一种通用、精确和可预测的方法。此外，这种方法还有助于通过减少与现有义齿相关的 CBCT 伪影以及捕获软组织轮廓来提高导板的质量，从而进一步改善手术导板的贴合度。
