| Abstract | ||
| The purpose of this study was to investigate soft tissue adaptability to hard tissue; in other words, to evaluate the relation between the inclination of upper and lower anterior teeth with the upper and lower lips, and how this relation affect the soft tissue profile in Class II division 1 malocclusion subject for both genders (males and females). The sample of this study comprised lateral cephalograms from 40 Class II division 1 malocclusion subjects (20 males and 20 females) aged 18–25 years. Two dental [upper and lower incisor inclination {the angle formed between the long axis of the upper central incisor (U1) and the palatal plane (PP) and the angle formed between the long axis of the lower central incisor (L1) and the mandibular plane (MP)}] and three soft tissue [nasolabial (nla), labiomental (lma) and soft tissue facial convexity (n–sn–pog)] angular measurements were analyzed. The results showed no significant difference between males and females concerning the proclination of upper anterior teeth and the prominency of upper lip, while the females exhibited more proclined lower anterior teeth and more protrusive lower lip than males. The males tend to have more convex facial profile than females | ||
