Abstract

Aims: To investigate the difference in soft tissue facial morphology in various groups of vertical facial pattern and to explore gender dimorphism within each type. Materials and Methods: One hundred and twenty Iraqi adults (60 males and 60 females) with Class I normal occlusion were selected. Standardized lateral cephalometric radiograph was taken for each subject and then the sample was divided into 3 groups according to vertical pattern, short, average and long facial types. Thirteen linear measurements were rec-orded on each lateral cephalometric radiograph and the data were analyzed using one way analysis of vari-ance and Duncan's multiple range analysis test and independent sample t test at p<0.05. Results: The short faced subjects showed the lowest dimension for lower facial height and lower lip height, while the long faced subjects exhibited thicker lower lip thickness at point B than the other 2 types. Gender dimorphism was recorded, as males showed thicker upper lip and lower lips, as well as longer upper facial height and lower lip height in the 3 groups of facial type. Conclusions: The soft tissue drape particularly facial verti-cal dimensions are influenced by the underlying skeletal vertical pattern
