Table 1 Short description of various parameters used in the study
Parameter | Short description |
|---|---|
ANB | The angle formed by the intersection of the point A to N (nasion) line and the point B to N (nasion) line (Figure 1) |
β angle | A perpendicular is dropped from point A to a line drawn from C (center of condyle) to point B. β angle is the angle between this perpendicular and the A-B line (Figure 2) |
YEN angle | Angle between the S (sella) to M (center of the premaxilla) line and the M to D (center of the symphysis) line (Figure 3) |
W angle | A perpendicular is dropped from M to the S-D line. W angle is measured between this perpendicular and the M-D line (Figure 4) |
APDI | (NPg-FH plane) ± ( NPg-AB) ± (FH-palatal plane) (Figure 5) |
Wits appraisal | Distance between the projection of point A and point B on the occlusal plane (Figure 6) |
App-Bpp | Distance between the projection of point A and point B on the palatal plane (Figure 6) |
