A digital workflow by means of intraoral scanners and computer tomography has been used in dental implantology, allowing clinicians to be potentially more accurate and precise. Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) and 3D models facilitate the process from treatment planning to the surgical procedure, up to the implant placement and final prosthesis. The aim of the present retrospective study was to evaluate a fully digital workflow for single-tooth implant rehabilitation. A total of 19 patients (22 implants) were included in the present study, with a mean follow-up time of 2 years. A fully digital workflow was performed on each patient through the planning, design and printing of a surgical guide, following a digital impression made with an intraoral scanner, computer-tomography-guided implant placement and, finally, with the delivery of a CAD-CAM crown. The two-year follow-up results were satisfactory in terms of the aesthetic yield and precision of the prosthesis. In single-implant-supported restorations, due to digital protocols and digital planning, a reduced number of clinical sessions was registered and the treatment plan results were more predictable. Future studies are needed to understand the application of fully digital protocols in cases of partially or totally edentulous patients.
通过口腔内扫描仪和计算机断层扫描的数字工作流程已应用于牙种植学，使临床医生可能更准确、精确。计算机辅助设计与计算机辅助制造（CAD-CAM）以及三维模型促进了从治疗计划到外科手术，直至种植体植入和最终修复体的整个过程。本回顾性研究的目的是评估单颗牙种植修复的全数字工作流程。本研究共纳入19例患者（22颗种植体），平均随访时间为2年。对每位患者进行全数字工作流程，包括通过口腔内扫描仪进行数字印模、计算机断层扫描引导下的种植体植入，以及最终制作CAD-CAM牙冠，随后进行手术导板的规划、设计和打印。两年的随访结果在美学效果和修复体精度方面令人满意。在单颗种植体支持的修复中，由于数字协议和数字规划，临床诊疗次数减少，治疗计划结果更具可预测性。未来需要开展研究以了解全数字协议在部分或完全无牙患者病例中的应用情况。
