Three scanning modalities were compared (n<\/jats:italic>\u2009=\u200910): (1) self\u2010developed structured light scanning with a mirror (SSLS); (2) intraoral scanner (IOS); and (3) photogrammetry system (PG). The scanners were stopped for 1\u2009min after each scan. Six scan bodies were analysed within each scan model. Linear deviations between the scan bodies (1\u20132, 1\u20133, 1\u20134, 1\u20135, and 1\u20136) and 3D mucosal deviations were established. The overall deviation was calculated as the mean of all linear deviations. \u201cTrueness\u201d represented the discrepancy between the test and reference files, while \u201cprecision\u201d denoted the consistency among the test files. Kruskal\u2013Wallis and Mann\u2013Whitney U tests were used for statistical analyses.<\/jats:p><\/jats:sec>Results<\/jats:title>Significant overall linear discrepancies were noted among the SSLS, PG, and IOS groups (p\u2009<<\/jats:italic>\u2009.001).

For the 3D mucosal deviation, the trueness (p<\/jats:italic>\u2009<\u2009.001) and precision (p\u2009<<\/jats:italic>\u2009.001) of the SSLS group were significantly better than those of the IOS group.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>The SSLS exhibited higher accuracy in determining the implant positions than the PG and IOS.
