Cephalometric analysis is a valuable tool used for diagnosis and treatment planning for dental malocclusion and underlying skeletal discrepancies. In view of the fact that a malocclusion is a product of an interaction between the alignment of the erupting teeth in their basal bone and the skeletal position of the basal bone itself, cephalometric analysis are used to evaluate dentoalveolar proportions and elucidate the anatomic basis for both jaw and tooth related abnormalities in the sagittal plane.
