- The dimensions and indices measured on lateral cephalometric radiographs were not statistically significant between men and women, except that the length of the anterior and posterior cranial bases in women was larger than in men; Most of the differences were statistically significant between the three types of occlusion according to the Angle classification except for skull base deviation, which did not show any difference (CC-N: 48, 92±3, 53 mm; Po-PtV: 37, 11±2, 35 mm; Ba-N / Xi-Pm: 60, 55±5, 09o; A / N-Pog: 1, 37±3, 03 mm; N-A / Fh: 90, 39±3, 06o; CC-Gn / Ba-N: 89, 11±4, 05o; N-Pog / Fh: 86, 64±4, 08o; Ls-E: 0, 47±2, 24 mm; Li-E: 0, 84±2, 25 mm; A1/B1: 122, 65±12, 08 o; R6HD / PtV: 11, 35±3, 23 mm).
