Accuracy was expressed as trueness and precision, usability as scan time, and feasibility as the number of total scan failures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods<\/jats:title>\n                    <jats:p>An edentulous mandibular model with four implants was fabricated with minimal surface morphology. Five scan body extension configurations were tested: no extensions (control), commercially available extensions, conventional impression copings used as extensions, and two morphological 3D\u2010printed extensions oriented between adjacent implants or toward the center of the arch. Two intraoral scanners were used. For each scanner and configuration, 30 scans were acquired. Inter\u2010implant distances were compared against coordinate measuring machine reference values. Trueness was assessed as mean absolute deviation, precision as standard deviation, and differences were analyzed with non\u2010parametric tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The highly morphological scan body extensions produced the most consistent improvements. Combined across scanners, trueness improved by 40\u201357\u2009\u03bcm relative to control for the longest inter\u2010implant span. Precision improved significantly for the center\u2010oriented configuration. All scan body extension techniques reduced scan time by 18%\u201341% and reduced scan failures from 13% (control) to 3% for the morphological designs. Improvements were most pronounced for longer spans and varied between scanners.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Highly morphological 3D\u2010printed scan body extensions significantly improved the accuracy, usability, and feasibility of complete\u2010arch digital implant impressions compared to an unmodified control workflow.
