Measurement | Abbreviation | Definition |
|---|---|---|
Maxillary length | ANS-PNS (mm) | Distance between the projection of PNS and ANS points onto the sagittal plane |
Maxillary width | J-J (mm) | Distance between the right and the left Jugale points (J) along the transverse axis |
Maxillary height | J-FHP (mm) | The perpendicular distance from Jugale points (J) to the FH plane |
Maxillary antero-posterior inclination | (PP/FHP) ° | The angle between of palatal plane (PP) and Frankfort plane (FHP) antero-posteriorly onto the sagittal plane |
Maxillary medio-lateral inclination | (J-J /FHP) ° | The angle between J-J line and Frankfort plane (FHP) medio-lateraly onto coronal plane |
