(a) Skeletal cephalometric measurements. 1. SNA: angle between the maxilla and the cranial base; 2. A-NPg: the distance between point A and NPg; 3. maxillary depth: angle between NA and Frankfort horizontal; 4. SNB: angle between the mandible and the cranial base; 5. Co-Gn: mandibular length between points Co and Gn; 6. Co-B: mandibular length between points Co and B; 7. Ar-Go: mandibular ramus height; 8. Co-Pg: mandibular length between points Co and Pg; 9. ANB: angle between the maxilla and mandible; 10. GoGnSN: angle between mandibular plane and SN; 11. FMA: angle between mandibular plane and Frankfort horizontal; and 12. ANS-Xi-Pm: lower facial height. (b) Dental cephalometric measurements. 1. overjet: horizontal overlap between upper and lower incisors; 2. overbite: vertical overlap between upper and lower incisors; 3. U1-SN: upper incisor inclination related to cranial base; 4. U1-APg: upper incisor inclination related to APg line; 5. U1-PTV: the distance between the tip of the upper incisor and PTV; 6. U6-PTV: the distance between the most distal point of the distal contour of the upper molar and PTV; 7. U1-FH: the distance between the tip of the upper incisor and the Frankfort horizontal; 8. U6-FH: the distance between the tip of the mesiobuccal cusp of the upper molar and the Frankfort horizontal; 9. IMPA: lower incisor inclination related to mandibular plane; 10. L1-APg: lower incisor inclination related to APg line; 11. L1-PTV: the distance between the tip of the lower incisor and PTV; 12. L6-PTV: the distance between the most distal point of the distal contour of the lower molar and PTV; 13. L1-GoMe: the distance between the tip of the lower incisor and mandibular plane; and 14. L6-GoMe: the distance between the tip of the mesiobuccal cusp of the lower molar and the mandibular plane.
