Digital impression systems are integral part of modern dental practice for the complete digital workflow. Digital intraoral scan containing the digital information of the oral cavity’s geometry generates a standard tessellation language (STL) file format, which is also essential during guided endodontics procedures. Direct and indirect methods can generate the STL file during classic computer-aided design (CAD)/computer-aided manufacturing (CAM) workflow. This chapter will discuss the fundamentals of digital impression systems and digital workflow, and describe a few available systems. These can generate the required STL file, which can be aligned on cone-beam computer tomography (CBCT) scans to design the guiding sleeve’s position during a guided endodontic procedure. The guided, virtually planned, minimally invasive access cavity ensures a quick and successful root canal access with the smallest possible loss of tooth structure.
