Purpose of Review

With the advent of CAD/CAM systems in dentistry, digital impressions have become an integral part of the treatment workflow in implant dentistry. The purpose of this article is to review the current status of digital impression systems, their applications within the digital workflow in implant dentistry, and the literature related to clinical viability in terms of its efficiency, accuracy, and patient-centered factors.

Recent Findings

The accuracy of intraoral scanners is similar to that of conventional impression techniques for single-crown and short-span fixed dental prosthesis (FDP) implant restorations. Clinical adjustment times were found to be shorter for dental implant crowns that were fabricated through a digital workflow than through a conventional one. Patients overwhelmingly prefer digital impressions over conventional methods in clinical studies.


Intraoral scanner systems are clinically viable tools for the taking of implant impressions, demonstrating comparable accuracy and improved efficiency as compared to conventional methods, when provided appropriate case selection. Conventional methods demonstrate better accuracy for full-arch cases and long-span FDPs. Due to the relative lack of clinical studies in this area, future investigative efforts should focus on in vivo investigation into the accuracy of digital implant impressions in a variety of clinical situations.
