“…The accuracy of Geomagic to make linear measurements was demonstrated by Sousa et al 20 in 2012. Because of the very high values of ICC tests, it was possible to ascertain that linear measurements to assess transverse changes in digital dental arches is reproducible using Geomagic.…”

Objectives: To investigate the predictability of arch expansion using Invisalign. Materials and Methods: Sixty-four adult white patients were selected to be part of this retrospective study. Pre-and posttreatment digital models created from an iTero scan were obtained from a single orthodontist practitioner. Digital models from Clincheck were also obtained from Align Technology. Linear values of upper and lower arch widths were measured for canines, premolars, and first molars at two different points: lingual gingival margins and cusp tips. A paired ttest was used to compare expansion planned on Clincheck with the posttreatment measurements. Variance ratio tests were used to determine if a larger change planned was associated with larger error.

“…In fact, recent advances in digital technology have vastly improved the diagnostic phase of orthodontic treatment, and analog records have quickly been replaced by digital formats [14]. Several studies in the literature have verified the accuracy of angular and linear measurements on three-dimensional digital models with different software [15,16]. Three-dimensional images allow to assess linear and angular measurements that describe the arch form and the morphology of the palatal vault [16].…”

“…Several studies have confirmed validity and reliability when measuring arch dimensions with either plaster or digital models 4,[16][17][18] . We can magnify the laser scanned digital model to mark out the desired point as the magnification of the virtual image is an excellent advantage compared with the plaster models, because of anatomic details can be more accurately viewed 19,20) . Zilberman et al, compared values of standard study model and virtual models (OrthoCAD) measurements by the use of nonparametric statistics, and methods' errors were also calculated.…”

The purpose of this study was to evaluate the validity and reliability of orthodontic measurements made on laser scanned 3D models created with NextEngine laser scanner and ScanStudioHD software. The data sources were plaster dental models from the archives of School of Dental Sciences, Universiti Sains Malaysia. A total of 100 dental models with 800 variables were measured using the plaster dental casts and laser scanned 3D models. The arch width, arch length, arch perimeter, LII, OJ and OB were measured by digital caliper (DC) and ScanStudio HD software. The validity (accuracy) of the digital measurements showed no statistical difference in any of the measurements performed. The reliability coefficient values were comparable between laser scanned 3D models and measurements using DC, the ICC coefficients were statistically significant (p<0.001), and the values of coefficient were in the range of strong correlation. The results show that linear measurements of dental casts using laser scanned 3D models are valid and reliable and can be used for various clinical orthodontic procedures.
