Purpose: To assess the effects of different sterilization methods on the trueness and precision of 3D-printed surgical guides. Methods: In this study, surgical guides were 3D-printed using resin to facilitate the planned placement of a missing mandibular right second premolar in a training model. Sterilization was performed using hydrogen peroxide plasma (55℃ for 25 minutes) and autoclaving (132℃ for 20 minutes, followed by a 30-minute drying cycle). Each surgical guide was scanned, and the data were exported in standard tessellation language format. The root mean square (RMS) values were calculated using 3D superimposition software, with the original design file as the reference data and the scan file of the 3D-printed guide as the measurement data. Thirty surgical guides were divided into three groups (n=10): non-sterile, plasma sterilization, and autoclave sterilization. Statistical analyses of the extracted RMS values were conducted using ANOVA for trueness assessment and the Kruskal–Wallis test for precision evaluation. Results: In the trueness evaluation, no statistically significant differences in RMS values were observed among the non-sterile, plasma sterilization, and autoclave sterilization groups (p>0.05). In contrast, the precision evaluation revealed significant differences among the groups, with the plasma sterilization group showing the lowest RMS value. Color map analysis showed relatively greater localized internal surface deviations in the autoclave sterilization group, whereas the plasma sterilization group exhibited comparatively uniform internal surface stability. Conclusion: The internal trueness of the 3D-printed surgical guides did not differ significantly depending on the sterilization method; however, a significant difference in precision was observed.
