Orthodontic treatment aims at correction of facial proportions and oral functions. Diagnostic imaging of the face and dental occlusion is necessary in order to assess growth and development, diagnose malocclusion, plan the treatment and evaluate the treatment outcomes (1–6). Radiographic assessment became more accurate by the use of multiplanar images including cone beam computed tomography (CBCT) scans. The introduction of the new generations of CBCT machines allowed significant reduction of radiation exposure and provided multiplanar imaging with high resolutions (7). Along with the multiplanar reformatting (MPR), CBCT also allows creating three-dimensional (3D) volume rendering which enables detailed 3D evaluation (7).
