Subjects were classified into two groups as \u201cAsymmetry group\u201d and \u201cSymmetry group\u201d. The distance from the most anterior and most inferior points of the ALIAN (IANant and IANinf) to the vertical and horizontal reference planes were measured (dAnt and dInf). The distance from IANant and IANinf to the mental foramen were also calculated (dAnt_MF and dInf_MF). The length of the mandibular body and symphysis area were measured. All measurements were analyzed using 3D analysis software.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There were 57 total eligible subjects. In the Asymmetry group, dAnt and dAnt_MF on the non-deviated side were significantly longer than the deviated side (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). dInf_MF on the non-deviated side was also significantly longer than the deviated side (<jats:italic>p<\/jats:italic>\u2009=\u20090.001). Mandibular body length was significantly longer on the non-deviated side (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). There was no significant difference in length in the symphysis area (<jats:italic>p<\/jats:italic>\u2009=\u20090.623).
