Computed tomography images used for linear and angular measurements of jaw symmetry. (Left) Horizontal deviation for maxilla (anterior nasal spine and upper incisor) and mandible (lower incisor and menton); ANS, anterior nasal spine; UI: upper incisor; LI: lower incisor; Me: menton. (Center) Vertical discrepancy for mandible (distance between point R and point L); point R: inflection point of mandibular body at the level of right mental foramen; point L: contralateral corresponding point of mandibular body on the left side. (Right) Horizontal discrepancy for mandible (distance discrepancy between dr and dl); dr: distance from point R to the facial midsagittal plane; dl: distance from point L to the facial midsagittal plane.
