Mesial bite, 20 year-old woman
A 20 year-old female was complaining about big protruded lower jaw and malocclusion. Examination of her face and occlusion revealed jaw size abnormality: small upper jaw and big lower jaw, mesial bite. Upper teeth were protruded and lower teeth were retruded, thus providing the best fit of dental arches at present position of jaws.
During the course of orthognathic treatment which lasted 2 years, dental arches were decompensated - teeth were inclined to the most physiological position and the crowding was reduced. After surgery performed on both jaws, new facial features brought harmony in the face. When jaws became similar in size, lip line and facial profile straightened up. Correct occlusion enabled proper chewing of food.
