Meanwhile, digital impressions were taken by an intraoral scanner. Implant planning software was used, considering a prosthetic-driven approach. Fully guided surgeries were executed. To evaluate the four groups of fully guided surgical guides, a digital imprint was obtained immediately after surgery. All STL files were imported into CAD software, and a digital library translated scan bodies to implant fixture replicas. For trueness tests, new STL files were loaded into an inspection program.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A single experienced surgeon inserted 86 implants using four different types of fully guided surgical guides.
