The irreversible trend toward digitization in dentistry and dental technology has resulted in technical progress and continuous changes to conventional workflows. In particular, implantology and prosthetics have benefited from a multitude of interesting new possibilities. Three-dimensional (3D) computed radiography and digital surface scanning can be invaluable in terms of backward planning and making implant surgery and denture fabrication more predictable. In this context, two digital implant-prosthetic treatment strategies are presented that allow for an efficient digital workflow while ensuring a minimally invasive surgical procedure. By means of digital intraoperative scanning of the implant position, the digital one-abutment/one-time concept allows for the insertion of computer-aided design/computer-aided manufacturing (CAD/CAM)-manufactured single crowns instantly after uncovering the implant. The second approach uses 3D radiographic data to preoperatively manufacture a one-piece root-analogue implant (RAI) and insert it immediately after tooth extraction. Both ideas promise some advantages in terms of quality and preservation of periimplant tissues as well as a noticeable reduction in overall treatment time.
牙科和牙科技术中不可逆转的数字化趋势带来了技术进步,并使传统工作流程不断变化。特别是,种植学和修复学受益于众多有趣的新可能性。三维(3D)计算机放射成像和数字表面扫描在逆向规划以及使种植手术和义齿制作更具可预测性方面可能具有极高价值。在此背景下,介绍了两种数字化种植修复治疗策略,它们在确保微创手术过程的同时,实现了高效的数字化工作流程。通过对种植体位置进行术中数字扫描,数字化单基台/一次性概念允许在暴露种植体后立即植入计算机辅助设计/计算机辅助制造(CAD/CAM)制作的单冠。第二种方法是利用3D放射成像数据在术前制作一体式牙根模拟种植体(RAI),并在拔牙后立即植入。这两种理念在种植体周围组织的质量和保存方面都有一些优势,并且显著缩短了整体治疗时间。
