After STL merging, each master STL file was used for printing a prosthesis prototype. The primary outcome was the accuracy of fit assessment of the printed prototypes on verified master stone casts. Two experienced clinicians tested the accuracy of fit with radiographs and screw\u2010resistance tests. Secondary outcomes were the effect of the scan body shape and implant number on the accuracy of fit.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Out of the 45 DDS\u2010generated prosthesis prototypes, 39 presented with accurate fit on verified master stone casts, yielding an 86.70% accuracy of fit. Cylindrical scan bodies led to 100% accuracy of fit (25\/25), whereas polygonal scan bodies presented with 70% accuracy of fit (14\/20). Four implant\u2010supported prostheses yielded 100% accuracy of fit (12\/12), compared with 25\/29 (86.30%) accuracy of fit for the six\u2010implant\u2010supported ones.
