Figure 3. A color presentation of the deviations between surfaces from the iTero® scanner. The color map was set to range from 0 µm to +200 µm. For the models in upper box A (C1R_ight, C2R_ight, C3R_ight, and C4R_ight), scanning started in the right molar region and then continued on the left side; in lower box B (C1L_eft, C2L_eft, C3L_eft, and C4L_eft), scanning started in the left molar region and then continued on the right side.

C1, Ideal arch dentition; C2, mildly crowded dentition; C3, moderately crowded dentition; C4, severely crowded dentition.
