Table 1 Measurements of mandibular ramus morphology

1. Mandibular angle: angle between two tangent lines of ower border and posterior border

2. ML–MF: distance from ML to MF

3. AP: anteroposterior ramal dimension at ML parallel to OP

4. ML–internal line: distance from ML to internal oblique line parallel to OP

5. ML–external line: distance from ML to external oblique line parallel to OP

6. ML–posterior line: distance from ML to posterior border of the ramus parallel to OP

7. ML–SN: distance from ML to the lower point of sigmoid notch

8. ML–second molar: distance from ML to the CEJ of mandibular second molar

9. ML–lower border: distance from ML to the lower border of ramus

10. ML–Go: distance from ML to Go
