Purpose: Th e aim of this study was to fi nd the correlation of transverse measurements obtained from 2-dimensional posteroanterior (PA) cephalogram and 3-dimensional computed tomography (CT). Methods: The subjects were 40 adult patients (25 males and 15 females, mean age: 22Y 8M) in Yonsei University Hospital with the diagnosis of skeletal Class III malocclusion. Transverse dimensions measured in PA cephalogram were correlated with respective measurements in CT. Results: Maxillary width (J-J) in PA had signifi cant correlation with all maxillary transverse dimensions in PA and CT, while mandibular width (Ag-Ag) in PA did not show signifi cant relation with mandibular measurements in CT. None of the measurements was found associated with the mandibular 1st molar width (L6a-L6a). Alveolar bone width of Mn canine (L3a-L3a) in CT was correlated with intercanine width of mandible (L3-L3) in PA. Conclusion: This study indicates that maxillary width (J-J) of PA may represent the maxillary alveolar transverse dimensions in CT, whrereas mandibular width (Ag-Ag) in PA may not be a useful indicator of mandibular basal arch width. Instead, mandibular intercanine width (L3-L3) in PA may represent the alveolar bone width of mandibular canine area.
