Abstract　： [Abstract] The relationship between the structures and development of the craniofacial morphology during aging is a major concern in the diagnosis, prevention, interception and treatment of malocclusion. The cant of the maxillary posterior occlusal plane is of particular interest because individual variations of this plane are related to changes in the mandibular position. The purpose of this study is to compare the cant of the occlusal plane in various skeletal frames and to analyze the correlation between the posterior occlusal plane and the morphology of various craniofacial structures. Models of 172 skulls (adult, Caucasian) were reconstructed using 3D cone beam computed tomography and several 3D cephalometric measures were compared and correlated. In the morphology of craniofacial structures, three parameters show a significant variation in dentoskeletal frames; the palatal plane angle, the mandibular plane angle and the cant of the posterior occlusal plane. The cant of the posterior occlusal plane shows significant correlations with various parameters, which may indicate its role in the development of craniofacial morphology. The cant of the posterior occlusal plane differs greatly from the morphology of the craniofacial architecture, and should be analyzed independently in the diagnosis and treatment planning of different malocclusions.
