Table 1 Cephalometric variables investigated in the present study
Variables | Definition |
|---|---|
SNA | the angle formed between points S, N, and A, indicating the anteroposterior projection of the maxilla |
SNB | the angle formed between points S, N, and B, indicating the anteroposterior projection of the mandible |
ANB | the angle formed between points A, N, and B, indicating the sagittal intermaxillary relationship |
SN (Anterior cranial fossa length) | the distance between the sella point (S) and nasion point (N) |
AH (Total anterior facial height) | the distance between the nasion point (N) and the menton point (Me) |
AHU (Upper anterior facial height) | the distance between the nasion point (N) and the anterior nasal spine point (ANS) |
AHL (Lower anterior facial height) | the distance between the anterior nasal spine (ANS) and menton point (Me) |
DIV (Intermaxillary angle) | the angle between the bispinal plane (ANS-PNS) and the mandibular plane (Go- Me) |
