[Evaluation of facial profile changes in individuals with skeletal Class II anomaly treated with activator and activator + occipital headgear].

The aim of this study is to evaluate the changes occurring in facial profile in individuals treated with activator and activator + occipital headgear. Our study is based on two treatment groups namely activator and activator + occipital headgear and one control group which received no orthodontic treatment. In each group there were 18 individuals of which 108 lateral cephalometric films were obtained reflecting before and after treatment/control periods. In this research 18 measurements were made. According to the results, it is found out that there exists difference in treatment groups in terms of the movement of lips related to Steiner soft tissue line.
