Objective: The purpose of this study was to evaluate the validity of the study models involved in the simulation training for dental technology using 3-dimensional virtual models. Methods: The study models and dental models from 25 young adult Korean were scanned as a virtual dental model with a 3-dimensional scanner (Scanner S600; Zirkonzahn). The dental arch form (arch width, arch length), buccolingual cusp inclination, and the radius of Monson’s sphere were measured on prepared virtual models using RapidForm2004 (INUS Technology Inc.). Wilcoxon signed-rank test was performed to verify the validity of the study models participating in the dental technique training using 3-dimensional virtual models (=0.05). Results: Arch width (intercanine width/intermolar width) and arch length (incisor to intercanine/incisor to intermolar) were smaller in both upper and lower study models than those of adult Korean models in general (p<0.05). In maxilla, buccolingual cusp inclinations of right and left side of premolars and molar were larger (2.21°-5.20°) in adult Korean models except for the first molar (p<0.05), which was the opposite in mandible (2.98°-9.20°) (p<0.05). The radii of Monson’ sphere was 104.92 mm in the study models and 121.85±47.11 mm in adult Korean models. There was no statistically significant difference between the two groups (p>0.05). Conclusion: In the study models involved in the simulation training, dental arch was smaller. Buccolingual cusp inclination was more inclined for upper and less inclined for lower than 25 subjects. This finding could be used as a meaningful reference for further studies focusing on validity on dental technique trainings for study models.
