Abstract

Abstract

Objective To evaluate the accuracy of digital models obtained using the iTero Element 1 intraoral scanner and traditional plaster models for measurements in mild to moderate crowding. Methods 37 patients who sought treatment at the Qinxing Road Clinic of Kunming Medical University Affiliated Stomatological Hospital were selected. The iTero Element 1 intraoral scanner was used to obtain digital models, while alginate impression was used to obtain traditional plaster models. The differences in digtal measurements and manual measurements of the traditional plaster models of tooth crown width, dental arch width, and coverage were compared. Results The ICC value of the three repeated measurements for both digital and plaster models were all above 0.9, indicating good repeatability. There were statistically significant differences in the arch width of 14～24 in mild and moderate crowded group, crown width （11、16、21、31、36、41、43、46） and 22 overjet in mild crowded group, and crown width of （11、23、16、31）and 11、12 overjet in moderate crowded group. Conclusion There are some differences between the data from iTero digital models and the manually measured plaster models in cases of mild to moderate crowding. This may be due to misalignment of teeth, leading to measurement errors. However, the differences in measurement data are small and do not affect the clinical application of iTero digital models.
