Illustrations of transverse skeletal and dental measurements. (A) posteroanterior cephalometric reference points (Mx: intersection of the lateral contour of the maxillary alveolar process and the lower contour of the maxillozygomatic process of the maxilla; Go: the most lateral point on the angle of the mandible) and lines (dotted) measuring the maxillary width (Mx-Mx) and mandibular width (Go-Go).23 (B) Intermolar width measurement from the most palatal aspects of the upper first molars at the level of the cementoenamel junction.24
