Facial and intraoral photographs, panoramic and lateral cephalometric radiographs, and virtual dental impressions were taken prior to orthodontic treatment (Figures 1 and 2). 3D digital models of the upper and lower jaws were obtained with the iTero HD 2.9 intraoral digital scanner (Align Technology, Inc., San Jose, CA) (Figure 3).

Manual alignment and global registration functions superimposed and fine-tuned the position of the two scans. 3D Compare analysis was performed which generated a 3D, color-coded map of the differences between the two palates (Figure 4).

The deviations for each of the three XYZ coordinate axes Dx, Dy, and Dz and the overall deviation magnitude values for the eleven variables were automatically calculated and recorded in the Geomagic software and then exported into Microsoft  Excel (Figure 5).
