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).

Evaluation of the occlusal vertical dimension by cephalometric analysis in dentate patients treated at the Norbert Wiener University Dental Center, 2023
(Universidad Privada Norbert Wiener, 2024-06-06) Lobato Avila, Elvis Luis; Guevara Sotomayor, Juan César
This thesis aimed to evaluate the occlusal vertical dimension (OVD) through cephalometric analysis in dentate patients treated at the Dental Center of the Universidad Norbert Wiener in 2023. A quantitative, applied, non-experimental, and cross-sectional study design was used. A total of 31 lateral cephalograms of adult dentate individuals were analyzed to establish the OVD, using a data collection sheet through the observation technique of the cephalometries. The first step was to verify general characteristics such as age and sex, then measure the distance from the tip of the nose to the tip of the chin, and finally, the occlusal vertical dimension was established through cephalometric analysis. It was observed that regarding OVD through cephalometric analysis, the upper angle showed a maximum value of 640 and a minimum of 400, with a mean of 51.640; the middle angle had a maximum value of 620 and a minimum of 260, with a mean of 48.030, and the transferred lower angle showed a maximum value of 590 and a minimum of 410, with a mean of 49.640. It was concluded that the occlusal vertical dimension through cephalometric analysis in dentate patients treated at the Dental Center of the Universidad Norbert Wiener in 2023 was an upper angle mean of 51.640, a middle angle mean of 48.030, and a transferred lower angle mean of 49.640.
