Half were sterilized by steam autoclaving with Cycle 1 (121\u00b0C, 1\u2009bar, 20.5\u2009min), half with Cycle 2 (134\u00b0C, 2\u2009bars, 5.5\u2009min). Before (T0) and after sterilization (T1) the guides were scanned with a structured light 3D scanner, and selected guides also with micro\u2010CT for validation. Linear measurements were performed in three axes on STL, and on T0 and T1 scans. Linear mixed\u2010effects models were used, followed by post\u2010hoc tests in case of significance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Measurements at T0 and T1 differed significantly from STL in both <jats:italic>x<\/jats:italic>\u2010 and <jats:italic>y<\/jats:italic>\u2010axis (4 and 3 PRCs, respectively) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05); in <jats:italic>z<\/jats:italic>\u2010axis only DLP\/Next showed significant differences between T0 and STL (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).

In the <jats:italic>z<\/jats:italic>\u2010axis all PRCs except for SLA\/DSG exhibited significant shrinkage (for Cycles 1 or 2).
