Flow diagram showing the processing of the cone-beam computed tomography (CBCT)-synthesized posteroanterior (PA) cephalograms. The raw CBCT data were imported using Dolphin software 11.95 Premium (Dolphin Imaging & Management Solutions, Chatsworth, CA, USA). The head position was adjusted to reduce layered bilateral structures. The ‘Build X-ray’ button in the software was used to synthesize the CBCT-PA with orthogonal X-ray exposure while eliminating virtual magnification, which causes image distortion.
