Different Angular and linear measurements used

Skeletal

1. Point A-N perp.   Distance from point A to Nasion perpendicular line

2. Pog-N perp.   Distance from Pog to the Nasion perpendicular line

3. F.MPA   The angle between the Frankfort plane and mandibular plane

4. Facial axis angle (F.A.A)   Angle between the basion-nasion plane and foramen rotundum- Gnathion plane

5. M.F.L   Effective midfacial length: distance from condylion to point A

6. Mand.L   Effective mandibular length: distance from condylion to Gnathion

7. L.F.H   Lower facial height: distance from ANS to Menton

Dental

1. Ui- point   A From labial surface of the upper incisor to point A

2. Li- A-Pog   From the edge of the lower incisor to a line from point A to Pog
