Post-functional cephalometric analysis
| Normal values | Patient values | Inference | |
| SNA (Sella–Nasion–A point angle) | 82±2° | 82° | Normally placed maxilla |
| SNB (Sella–Nasion–B point angle) | 80±2° | 79.5° | Backwardly placed mandible |
| ANB (A point–Nasion–B point angle) | 2° | 2.5° | Class II skeletal pattern |
| Effective maxillary length | 92.1±4.1mm | 95 mm | Normal for age |
| Effective mandibular length | 114.4±4.3mm | 117 mm | Normal for age For 95 mm maxilla, the mandible should be 122–125 mm, according to McNamara’s growth prediction. Hence, mandibular length is short by 8 mm for that maxilla. |
| FMA (Frankfort-mandibular plane angle) | 17°–28° | 23° | Average growth pattern |
| SN-GoGn (Sella-Nasion to Gonion-Gnathion angle) | 32° | 33° | Average growth pattern |
| Y-axis | 53°–66° | 65.9° | Average growth pattern |
| U1–SN (Upper incisor-Sella-Nasion angle) | 102° | 114° | Proclined upper incisors |
| U1–NA (Upper incisor-Nasion-Point A angle) | |||
| Linear | 4 mm | 6.7 mm | Forwardly placed upper incisors |
| Degree | 22° | 25.7° | Proclined upper incisors |
| L1–NB (Lower incisor-Nasion-Point B angle) | |||
| Linear | 4 mm | 8.3 mm | Forwardly placed lower incisors |
| Degree | 25° | 35.6° | Proclined lower incisors |
| L1–A-Pog (Lower incisor to Point A-Pogonion angle) | 2 mm | 5.9 mm | Normally placed lower incisors |
| U1–L1 (Upper incisor-Lower incisor angle) | 135° | 116° | Bidental proclination |
| IMPA (Incisor mandibular plane angle) | 90° | 105.8° | Proclined lower incisor |
| Cant of occlusion | 1.5°–14° | 8° | Normal |
| Nasolabial angle | 90° –110° | 100° | Normal |
| Lip strain | 2 mm | Lip strain of 2 mm |
