Educational Objectives

The overall goal of this article is to provide the reader with information on digital impressions.
After completing this article, the reader will be able to:

1. Describe the changes that have occurred in digital impression technologies

2. List and describe differences between digital and traditional impression techniques

3. Review the differences between open and closed architecture, scanning options and
restorative options with different systems.


Digital technologies have changed the world we live in, and have also resulted in significant changes in dentistry. One of these was digital impressioning, together with
CAD/CAM. Digital dental impressions were first introduced in the 1980s, with two available options: scanning and chairside milling of inlays and onlays; and digital scanning of stone models that had been poured from traditional impressions. Much has changed since then. The evolution of digital impressioning has resulted in it now being utilized for restorative care, implant components, splints, orthodontics and dentures. Digital impressioning is now mainstream. In the case of restorative care, not only the availability of accurate CAD/CAM systems5 but also esthetic and durable CAM restorative materials and advanced adhesive technologies have promoted the adoption of digital impression techniques.
