Dependence of the face aesthetic from sagittal and vertical jaw relations

Abstract

Treatment plan in contemporary orthodontics cannot be imagine without analyzing soft tissue facial characteristics besides assessment of jaw and dental relationships. Aim. Using a questionnaire, we aimed this study at establishing facial characteristics, in relation to sagittal and vertical facial ratios, which are considered aesthetically acceptable, and which could be altered by the means orthodontic treatment. Material and Method. The research was conducted in persons from 23 to 30 years of age whose photographs were taken in standard conditions. Photographs of three patients with different facial profiles were chosen (Class I, Class II and Class III). Every photo was modified in six new profiles by changing facial features. This included mesial and distal shift of maxilla and mandible, as well as increase and decrease of lower facial height. Results. The results showed that straight profile, which is most often present in normal jaw relationships, is considered the most beautiful, furthermore slightly convex profiles are also considered very attractive. Convex profile is connected with distal jaw relationship and its intensity affects facial attractiveness. Concave profile in patients with mesial jaw relationship is aesthetically the least acceptable.
