| SN-MxOP |
Angle formed by SN and the maxillary occlusal plane (plane drawn through the mesiobuccal cusp tip of the maxillary molar to the upper central incisor tip) |
| SN-MnOP |
Angle formed by SN and the mandibular occlusal plane (plane drawn through the mesiobuccal cusp tip of the mandibular molar to the lower central incisor tip) |
| MP-MnOP |
Angle formed by mandibular plane (inferior gonion to menton) and the mandibular occlusal plane |
| SN-PP |
Angle formed by SN to palatal plane (ANS to PNS) |
| SN-MP |
Angle formed by SN to mandibular plane (inferior gonion to menton) |
| SN-GoGn |
Angle formed by SN and the plane drawn through the points inferior gonion and gnathion |
| U1-PP |
The millimetric distance between U1 tip and the palatal plane (ANS to PNS) |
| L1-GoGn |
The millimetric distance between L1 tip and the plane drawn through inferior gonion-gnathion |
