Cephalometrics evaluation	Description
N-Ba (mm)	The distance between Nasion (anterior part of nasal bone) and Basion (the postero-inferior part of Sfenoid bone)
Co-GN (mm)	The distance between Condilion (upper part of mandibular condyle) and Gnation (the anterion part of mandibular symphysis)
ANS-PNS (mm)	The distance between SNA (anterior nasal spine) and PNS (postero-nasal spine)
MXL-BL°	The angle between the MXL (maxillary line) and BL (anterior cranial base line)
MXL-Co-Gn°	The angle between MXL (maxillary line) and CO-GN line (the condilion-gnation line)
