Morphometric analysis of the hard palate. A and B Axial reconstructions—green line positioned in the median sagittal plane and perpendicular to the purple line, which passes over the palatine roots of the upper first premolars and first molars. A Coronal reconstruction—measurement of hard palate width (green line) and height (yellow line) at the first premolars region. B Coronal reconstruction—measurement of the hard palate width (green line) and height (yellow line) at the first molars region. 1st PM first premolar; 1st Ms: first molar; R: right; L: left.
