Table 2 List and definition of all the measurements used in the present study
Measurement | Definition |
|---|---|
Angular (°) | |
PP-MP | The angle between the palatine plane (PP), passing through Ans and Pns, and mandibular plane (MP) |
PP-OP | The angle between the palatine plane (PP), passing through Ans and Pns, and occlusal plane |
OP-MP | The angle between the occlusal plane (OP), passing through the incisal edge of U1 to the midpoint of the U6 on the occlusal, and mandibular plane (MP) |
AFH | The anterior facial height (Na-Me) expressed in percentage |
PFH | The posterior facial height(S-Go) |
Linear (mm) | |
Δ7MB | Post-treatment difference in the linear distance from the mesio-buccal cusp of the second mandibular molar to the reference plane |
Δ6MB | Post-treatment difference in the linear distance from the mesio-buccal cusp of the first mandibular molar to the reference plane |
Δ5B | Difference after treatment linear distance between buccal cusp of second premolar and reference plane |
Δ4B | Difference after treatment linear distance between buccal cusp of the first premolar and reference plane |
