To introduce a novel digital workflow to replace a terminal or a complete edentulous arch with a complete-arch implant-supported fixed prosthesis.
A novel fully digital protocol provides an interim and definitive prosthesis by integrating extraoral dental photogrammetry with intraoral scanners.
The described technique has great potential to deliver a complete-arch implant-supported fixed interim and definitive prosthesis in edentulous patients in an efficient way.
In the era of digital dentistry, using a fully digital workflow in full arch implant rehabilitations might be beneficial to replace multistep conventional methods.
Why is this case new information? To the author's knowledge, this article illustrates the first step-by-step technique that combines intraoral scanning with dental photogrammetry to provide a full-arch implant-supported interim and definitive prosthesis. What are the keys to successful management of this case? Well-defined presurgical planning and adequate primary stability of the dental implants. Accurate digital impressions of the scan bodies. A dental laboratory that is familiar with digital workflow for complete-arch rehabilitations. What are the primary limitations to success in this case? The learning curve of the scanning procedure. The cost barriers to acquire intraoral and photogrammetry scanners. Limited clinical studies that investigated the accuracy of intraoral scanning and dental photogrammetry for complete-arch digital implant impression.
引入一种新型数字工作流程，用全牙弓种植体支持的固定修复体替代单个牙或整个无牙颌弓。
一种新型全数字方案通过将口腔外牙科摄影测量与口内扫描仪相结合，提供临时和最终修复体。
所描述的技术有很大潜力以高效方式为无牙患者提供全牙弓种植体支持的固定临时和最终修复体。
在数字牙科时代，在全牙弓种植修复中使用全数字工作流程可能有利于取代多步骤传统方法。
为什么这个病例是新信息？据作者所知，本文阐述了将口内扫描与牙科摄影测量相结合以提供全牙弓种植体支持的临时和最终修复体的首个分步技术。成功处理这个病例的关键是什么？明确的术前规划和牙种植体足够的初期稳定性。扫描体的精确数字印模。熟悉全牙弓修复数字工作流程的牙科实验室。这个病例成功的主要限制是什么？扫描程序的学习曲线。获取口内扫描仪和摄影测量扫描仪的成本障碍。研究全牙弓数字种植印模的口内扫描和牙科摄影测量准确性的临床研究有限。
