Figure 3. Soft tissue and skeletal cephalometric analysis. 1, The upper lip to the E line; 2, the lower lip to the E line; 3, the sella-nasion to the palatal plane angle (SN-PP); 4, the SN-anatomic occlusal plane angle (SN-Occ); 5, the SN to the mandibular plane angle (SN-Mn); 6, the distance between the pterygoid vertical plane and point A (PTV-A); 7, the distance between the pterygoid vertical plane and point B (PTV-B); and 8, the lower anterior face height (LAFH; ANS-Me). Refer Table 2 for definitions of the landmarks.
