Lateral Cephalometric Assessment of Bimaxillary Dentoalveolar Protrusion among Filipino Adult Patients with Emphasis on Growth Pattern

This research is conducted to evaluate the bimaxillary protrusion in adult Filipino subjects according the inclusive criteria of this study to investigate the behavior of the discrepancy. Seventy cephalograms were selected according the inclusive and the exclusive criteria for bimaxillary protrusion. Then all were traced and analyzed by the cephalometric analysis with related variables which used in the study. Results of the study showed that the patients with bimaxillary protrusion indicated the high angle mandibular plane partly due to excessive upper posterior dentoalveolar height and partly because of short ramus. The patients showed hyperdivergent facial pattern with decreased overbite which demonstrated skeletal openbite and long face pattern. Filipino patients with bimaxillary protrusion have varied degrees of skeletal vertical discrepancy which makes the primary horizontal discrepancy more complicated. Hence, vertical consideration before any corrective treatment should take into the account regarding the limitations of the orthodontic treatment, especially in the severe cases.
