Summary

The study will monitor changes induced by orthodontic treatment and in the retention period, two years after the end of orthodontic treatment. The alignment of teeth, hygiene and gingiva will be assessed. Efficiency of two types of fixed appliances in active phase will be compared - esthetic and metal. Efficiency of two types of retention appliances in retention phase will be compared - fixed and removable. The benefits of orthodontic treatment to be studied are aesthetic concerns, dental self-confidence, self-esteem, social contacts, psychological influences, and chewing limitation. The stability of personality traits, body image and perfectionism will also be analyzed, as well as the extent to which these dimensions modify the reporting of psychosocial effects of malocclusion treatment.
