概要	This study aimed to assess the accuracy of digital dental models obtained using a new non-contact 3D measuring system compared to direct measurements made on plaster models as the gold standard. The means of the 10 parameters were different between the 2 methods, and the absolute differences ranged between 0.07 and 0.23 mm; some of which were statistically significant. However, all these differences were less than 0.3 mm, so are not considered clinically significant. The ratios of standard deviation were larger than 1 in 7 of 10 parameters, suggesting that the reproducibility of the 3D scanner was slightly less reproducible than the direct measurements, but still clinically acceptable. Our non-contact 3D measuring system showed high reliability on repeated measurement.
