The relationship between vertical facial growth patterns and palatal morphology in Class I and Class II malocclusion cases is explored. An in vitro analysis of 24 subjects (12 in each group) showed that individuals with Class II malocclusion and high-angle growth displayed significantly greater mandibular plane angles, facial heights, palatal widths, and arch lengths compared to their Class I counterparts. Data shows that vertical growth tendencies have a marked influence on palatal dimensions. Visual data representation further confirmed the distinctive morphological differences between the groups. Thus, the need to account for vertical facial growth patterns in orthodontic diagnostics and treatment planning is reported.
