Fig. 2From: Evaluation of trabecular changes following advancement genioplasty combined with or without bilateral sagittal split osteotomy by fractal analysis: a retrospective cohort studyThe region of interests (ROIs) was obtained from the panoramic radiographs, a square of 50 × 50 pixels. ROI 1: right region of the separated genial segment. ROI 2: left region of the separated genial segment. ROI 3: middle region of the separated genial segment. ROI 4: region selected in the right mandibular angulus. ROI 5: selected region in left mandibular angulus. ROI 6: healing region between the separated genial segment and mandibular corpusBack to article page
