Mandibular Geometry Analysis from CT Scans

All linear and CSA measurements were controlled for general mandibular size, as expressed by its geometric mean (MGM—mandibular geometric mean). The latter was calculated based on a set of six linear measurements: ramus length and width, mandibular body length, gonial width, coronoid length, andbigonial breadth, following the methods described by Sella Tunis et al. [28 (link)]. All measurements were taken directly from the CT scans using the Brilliance Workspace Portal (Philips v. 2.6.1.5, Philips, Amsterdam, Netherlands). The square roots of the chin and symphysis CSAs were divided by the MGM, following the principles presented in Jungers et al. [29 (link)].
