The aim of this clinical report is to describe a complete digital workflow protocol for mandibular full-arch implant rehabilitation from guided surgery to definitive prosthesis in only 3 appointments. This expedited protocol allows for guided implant placement with a system of stackable surgical templates and CAD/CAM prosthodontic rehabilitation using a digital workflow. At the first appointment, a guided implant placement protocol with the stackable template concept was done followed by immediate loading with a prefabricated interim prosthesis. At the same appointment, the Double Digital Scanning (DDS) technique was used for scanning, maxillomandibular relationship registration and virtual articulation. The anchor pins from guided surgery were used as fiducial markers for DDS data superimposition. At the second appointment, the prosthesis prototype was tried-in and adjustments were made. At the third appointment, the definitive monolithic zirconia full-arch prosthesis was delivered.
本临床报告的目的是描述一种完整的数字化工作流程方案，用于从引导性手术到最终义齿修复，仅在 3 次就诊内完成下颌全颌种植修复。该加速方案允许使用堆叠式手术模板系统进行引导性种植体植入，并使用数字化工作流程进行 CAD/CAM 修复体修复。在第一次就诊时，采用堆叠式模板概念进行引导性种植体植入，并立即加载预制临时义齿。在同一次就诊时，使用双数字化扫描 (DDS) 技术进行扫描、上下颌关系登记和虚拟咬合。引导手术中的定位销用作 DDS 数据叠加的基准标记。在第二次就诊时，试戴义齿原型并进行调整。在第三次就诊时，交付最终的整体氧化锆全颌义齿。
