Objective: The aim of this study was to determine average values of profile teleradiographs of the angles between the occlusal plane and five craniofacial planes in a Moroccan population.
Methods: In this cross-sectional study, we collected 160 profile teleradiographs of adult patients (XX females and XXX males) with class I dental occlusion who underwent treatment from March, 2021 to July, 2021. Patients were divided into three groups according to vertical facial type: group I (normodivergent; n = 47), group II (hypodivergent; n = 36) and group III (hyperdivergent; n = 77).
Results: The results indicated that the mean angles between the occlusal plane and the five craniofacial structures examined were 8.6° for the Frankfort Horizontal plane, 10.6° for the Camper plane, 11.4° for the Palatine plane, 13.3° for the Axio-orbital plane and 18.6° for the Mandibular plane.
Conclusion: The comparison of global mean values with mean values for each group of patients suggested that angle mean values in hypodivergent cases were lower than the overall values and significantly higher than the overall values. With respect to normodivergent cases, a significant difference was noted only for the POPM and POPC values, which were lower than the sample’s mean. To orient the occlusal plane, cephalometry, combined with other reference planes, can be used as an adjunct to position the occlusal plane; that is with profile teleradiography.
