Soft tissue parameters variability in patients with normal dental occlusion

Abstract

Facial aesthetics can be characterized by both subjective and objective data. The subjective view depends on many factors: gender, age, education level, population, race, ethnic group, fashion.Aim. Determine of soft tissue variability parameters in individuals with physiological occlusion.Materials and methods: a photometric examination of 20 persons with normal occlusion aged 20-24 years was carried out. There were used 12 soft tissue points on face profile and 6 front points for the photometric study. We researched soft tissue’s transversal parameters in full face structures and the angular parameters. Also we researched soft tissue profile’s ratio of points and planes to the true vertical and horizontal, and the face parts ratio reflecting indices.Results. It was determined that papameters have the maximum variability: under/beard line rotation, cervical-chin angle, cervical angle, cervical index, nose, middle and lower heights face ratio rotation angle. Facial Changes index shows that 35% of the studied subjects were classified as mild, 45% as moderate, and 20% as severe.Conclusions. The of the standards narrow framework does not allow taking into account the individual, ethnic, gender and age components of the face aesthetic perception. There is needed norms Greater individualization, an index evaluation increase role and face parts ratio analysis.
