Fig. 4From: Preliminary comparison of three-dimensional reconstructed palatal morphology in subjects with different sagittal and vertical patterns3D coordinate system. a, The three-dimensional (3D) coordinate system of the palatal morphology. U1’, The origin; Plane XY, the horizontal plane; Plane YZ, the sagittal plane; and Plane XZ, the coronal plane. b, The average 3D palatal morphology for each group established by the method of average calculationBack to article page
