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
