Abstract

The aim of this study is to compare the arc length deviation, arc length, Bolton analysis, overjet and overbite values obtained from OrthoCAD software of plaster models, transferred to the three-dimensional environment with the iTero Element 2 intraoral scanner, with conventional methods. The study included plaster model obtained from a total of 30 individuals aged 18-25 years old, Angle Class I, Angle Class II and Angle Class III who obtained for orthodontic treatment. Models were digitized with iTero Element 2 intraoral scanners. To determine the arc length deviation, arc length, Bolton analysis, overjet and overbite, measurements were carried out on the models. The measurements were repeated 30 days apart from each other. For the characteristics considered, descriptive statistics are expressed as mean, standard deviation, minimum and maximum value. In terms of these characteristics, the paired sample t-test was used to compare the first and second measurement differences. In terms of arc length deviation, overjet, and overbite values, there was no statistically significant difference between the groups. A statistically significant difference was found between the two methods for lower arch length measurements. A statistically significant difference in the anterior ratio was found in the Bolton analysis, while no statistically significant difference in the overall ratio was observed. When compared to traditional approaches, the values obtained on the models obtained with the iTero 2 Element 3D scanner and the OrthoCAD software are thought to be accurate and alternative
