Digital evaluation of marginal and internal fit of single-crown fixed dental prostheses
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.
