[Vertical superposition on distance radiography in norma lateralis: normal or asymmetrical?]

Cephalometric analysis, together with clinical examination and study of models, is an essential tool in practitioners' preparations of orthodontic diagnoses for their patients. However, despite the use of standardized techniques, cephalograms in norma lateralis still inescapably superimpose patients' right and left sides on each other. This study attempts to demonstrate the significance of these superimpositions particularly when serial cephalograms are themselves superimposed on each other to discern growth or treatment changes.
