This study evaluated the concordance of Steiner, Ricketts, and the Element II of Andrews' Philosophy cephalometric analyses for determining the antero-posterior relationship of the upper maxilla in patients from the orthodontics second specialty clinic of the Universidad Norbert Wiener during the 2014-II to 2015-I period. It is an observational, prospective, cross-sectional study with a descriptive research level and a community or ecological design for multiple comparisons. Thirty cephalometric tracings were performed, which were evaluated by a single examiner. Each tracing underwent two cephalometric studies, and Element II of Andrews' philosophy was evaluated to determine the antero-posterior position of the upper maxilla. Results: The Steiner cephalometric analysis showed that 53% of patients had maxillary protrusion. The Ricketts cephalometric analysis showed that 57% of patients were within normal limits, and Element II of Andrews' philosophy showed that 60% of patients had maxillary retrusion. Using the Kappa statistical test, the study concluded that there was no concordance between the Steiner and Ricketts analyses (0.01946) for determining the antero-posterior position of the upper maxilla; nor was there concordance between the Element II of Andrews and Steiner cephalometric analysis (0.0865), or between Element II of Andrews and Ricketts cephalometric analysis (0.0948).
