Purpose: The present study aimed to assess the accuracy and reproducibility of laser-scanned digital models compared to plaster models. Materials and Methods: A total of 50 plaster models were scanned using the 3M ESPE Lava scan ST scanner to construct digital models. Various measurements, encompassing intra-arch and inter-arch from scans and plaster models, were estimated. The plaster models were measured using digital calipers and digital models using MiniMagics 3.0 software. Descriptive statistics were calculated, and the mean difference of the parameters between the two groups was tested by paired t-test. Results: No significant difference was detected between the digital and manual measurements in the majority of the parameters, and the values for the parameters showed significant differences that were not clinically applicable. The digital method showed good reproducibility for all the measurements (r > 0.7). Overbite showed a marked variation between the manual and digital measurements due to overlapping tooth structures in digital models with respect to ideal occlusion. Bolton's analysis did not show a significant difference between the manual and digital methods. Conclusions: Digital models could be compared to the gold standard plaster models.
