Facial symmetry in subjects with full dental arches

Abstract

The universal notion of beauty does not exists, however, the facial symmetry contributes to a better aesthetic effect. This harmony is primarily determined by the relationship between parts of the face and dental parameters. Tooth loss leads to a decrease in the height of the bite and consecutive oncoming of the tip of the nose and chin and a violation of the vertical and horizontal relationship between the maxilla and mandible. The aim of the study was to determine the interrelationship of facial parts in subjects with a full dentition. The study included 60 dental students of both sexes in whom the presence of a complete dentition was determined by clinical examination. Facial parameters of the subjects' profiles were measured, as well as the ratio of bipupillary distance and intercommissural distance. The obtained results partially confirmed the theory of matching the heights of the profile thirds and halves of the face. The values of the distance between the two pupils and the lip commissure did not differ statistically significantly. The obtained results could be used in the reconstruction of intermaxillary relationships after the loss of some or all teeth.
