  1. SD: Standard Deviation. ROI: Region of Interest
  2. 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 area between the separated genial segment and mandibular corpus
  3. † This ROI measurement was performed only to evaluate the healing of the area between the mandibular corpus and genial segment at the time-point of the T1. * Result of Friedman Repeated Measures Analysis of Variance on Ranks test. ** Results of All Pairwise Multiple Comparison Procedures (Student-Newman-Keuls Method). The same letters in the column indicate that there is no difference in pairwise comparison
