Malocclusions are manifested with changes in the teeth position, different position of the bones of maxilla and mandible are often accompanied by soft tissue changes. Orthodontic treatment also affects the changes of soft tissue structures, and improves the facial aesthetics of the patients. In order to see the benefits of orthodontic therapy in Class II/1 malocclusion, an analysis of the changes that occur in the soft tissues and lips in patients before and after, was performed. For this purpose, 7 soft tissue parameters of the lips were analyzed in 30 patients with Class II Division 1 malocclusion, before and after orthodontic treatment, and in 30 patients with normal occlusion. The results indicate that after orthodontic treatment in patients with Class II/1 malocclusion, there are significant changes in the upper smile line, the height of the upper lip at rest position and during the smile and for the intercommissural length. From the analysis it can be concluded that the soft tissues follow the changes that occur with orthodontic treatment, which positively affects the aesthetics of the lips and the smile.
