The development of digital techniques in dentistry is rapid. The use of 3D-printing for the production of resin-based constructions has become more widespread in recent years and new materials, printers and accessories are constantly becoming available.

The adaptation of single-crown fixed dental prostheses (FDPs) is a subject of great interest in the research community. Many investigations have been published, and a variety of evaluation methods have been used to determine the fit accuracy of prosthetics.
Many of the methods required manual measurements of the gap between the restoration and the abutment. With the introduction of CAD/CAM techniques, digital tools started being used for evaluating the adaptation of FDPs.
In this study, a tabletop dental scanner was used. It is anticipated that in a clinical setting, an intraoral scanner is sufficient, at least for single-crown FDPs.

Suboptimal adaptation of fixed dental prostheses (FDPs) can lead to technical and biological complications. It is unclear if the computer-aided design/computer-aided manufacturing (CAD/CAM) technique improves adaptation of FDPs compared with FDPs made using the lost-wax and metal casting technique.

With equipment for computer-aided design and manufacturing (CAD/CAM) in the dental office, the dentist again becomes his own dental technician. While the equipment itself is not subject to health-related regulation, the European Medical Devices Directive imposes requirements on the prosthodontic devices it produces
