The dentoalveolar mechanism, within the dentofacial complex, acts to camouflage the vertical base bone discrepancies resulting in differences in the functional occlusal plane cant (FOPC). Considering this, ensures more stable orthodontic treatment re
sults. This research aims to study the possibility of a relationship between the FOPC (represented by anterior and posterior occlusal planes) and the vertical facial growth patterns (VFGPs) using cone beam computed tomography (CBCT). The research sample consisted of 50 CBCTs (22 males and 28 females) aged 18 to 35 years with no prior orthodontic treatments. Their FOPCs were studied according to the VFGPs. Pearson's correlation coefficient was then calculated for all the data obtained. The study showed that the posterior occlusal plane has a clearer correlation to the VFGPs than to the traditional occlusal plane. The posterior occlusal plane showed a strong correlation with the VFGPs in the female sample.
