Titanium and PEEK scan bodies were scanned using an intraoral scanner, with the initial scan serving as the reference. Each scan body underwent 14 steam autoclave cycles (134\u00b0C for 10 min followed by 15 min drying). Scans were exported as STL files and superimposed onto the reference dataset. Linear, angular, diameter, and root mean square (RMS) deviations were measured.\n <\/jats:p>\n <\/jats:sec>\n \n Statistical Analysis Used:<\/jats:title>\n \n Data were analyzed using repeated measures analysis of variance (ANOVA). Mean differences with 95% confidence intervals were calculated, and statistical significance was set at\n P<\/jats:italic>\n < 0.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Both materials showed deviations after repeated sterilization; however, titanium scan bodies exhibited significantly lower linear, angular, and RMS deviations.
