Accuracy Analysis of Extraoral 3D Scanning in the Development of Dental Prosthetic.

Objective: The study has evaluated the accuracy (trueness and precision) of seven extraoral scanners when scanning two different types of jaws: simplified jaw with sharp edges and abutments and realistic jaw with natural teeth. The accuracies of extraoral scanners were compared, and their compliance with the required clinical accuracy levels was discussed.

Material And Methods: Ten scans were made with each scanner for both models.
