Each patient received four or six dental implants (Straumann BLX). Both CI and DI were performed using randomized sequences. Linear and angular deviations were measured between the reference scan (coordinated measuring machine) and the CI (desktop scanner) and DI (intraoral scanner, IOS) using CATIA software (Dassault Syst\u00e8mes). Framework passivity was evaluated using the Sheffield one\u2010screw test. The Shapiro\u2013Wilk test determined data normality (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), and nonparametric statistical tests were applied using statistical software.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Descriptive statistics showed a mean linear discrepancy of 29.05 (84.80\u2009\u03bcm) for CI and 6.95 (154.10\u2009\u03bcm) for DI, with angular deviations of 0.06\u00b0 (0.36\u00b0) for CI and 0.05\u00b0 (1.40\u00b0) for DI. No statistically significant differences were found in linear (<jats:italic>p<\/jats:italic>\u2009=\u20090.38) or angular (<jats:italic>p<\/jats:italic>\u2009=\u20090.12) measurements between CI and DI. Framework passivity testing showed that both techniques achieved passive fit in 17 out of 20 cases (85%), with the reference scan achieving passivity in 18 (90%) cases. Distal implants, particularly in the upper jaw, exhibited greater discrepancies, but none were statistically significant.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>No significant differences in trueness were found between CI and DI techniques.
