Feres3 Marcio Vinícius H. de Quadros4 Abstract Objective: To propose a cephalometric factor that reports the mean and standard deviation of posterior alveolar height at upper first molars level. Methods: Fifty-one (51) cephalometric radiographs of mesofacial individuals were used to obtain cephalometric tracings using the Radio Manager 7.0 program. The distance from the perpendicular initiated in the palatal plane to the mesiobuccal cusp of the first maxillary molar was measured. Data from the research of Brandão Filho et al was used as a control sample. Results: A clinical standard value of 23.3mm was obtained, with a standard deviation of ± 2.78mm (p = 0.9790). Conclusion: The clinical mean and standard deviation of the proposed cephalometric factor contributes to the diagnosis and treatment plan for vertical dysplasias.
