Accuracy of conventional and 3D printed casts for partial fixed prosthesis

Purpose: To evaluate and compare the accuracy of conventional and 3D-printed casts using five different 3D printers. Materials and Methods: In the control group (CG group, n = 5), five conventional impressions using light- and heavy-body polyvinyl siloxane were obtained from the master model, resulting in five stone models. In the test groups, five different scans were performed by a well-trained and experienced clinician using a TRIOS intraoral
