|
Gnathion-interdental distance (Gn-IdD) | Direct distance from infradentale (idD) to gnathion (Gn). |
| Bigonial width (Go-GoD) | Direct distance between right and left gonion (Go). |
| Bicondylar breadth (Ko-KoD) | Direct distance between the most lateral points on the two condyles. |
| Height of the mandibular body (VTM) | Direct distance from the alveolar process to the inferior border of the mandible perpendicular to the base at the level of the mental foramen. |
| Breadth of the mandibular body (STM) | Maximum breadth measured in the region of the mental foramen perpendicular to the long axis of the mandibular body. |
| Mandibular length (DTM) | Distance of the anterior margin of the chin from a center point on the protected straight line placed along the posterior border of the two mandibular angles. |
| Minimum ramus breadth (MSR) | Least breadth of the mandibular ramus measured perpendicular to the height of the ramus. |
| Maximum ramus height (MVR) | Direct distance from the highest point on the mandibular condyle to gonion (Go). |
| Height of the condyles (VKo) | Distance between Kon and axis of the lowest point of mandibular cut perpendicular to MVR. |
| Gnathion-condylar distance (Gn-KoD) | Distance between Gn and Kon. |
