Aim: to evaluate the reliability in the identification of the markers observed in frontal Cephalometric x-rays. Methods: in 3 dry humans skull were adapted expansor appliances, in which markers were attached at orthodontics brackets and tubes. Results: the statistical comparison of the 27 postero-anterior cephalograms revealed that the angular measures showed small variations; however the smallest error were for the lineal measures among the markers. Conclusion: the markers demonstrated its reliability for the use in longitudinal researches with frontal cephalometric x-rays.

Keywords: Frontal cephalometric radiography. Frontal cephalometric. Maxillary expansion.
