Introduction: beauty has an "ideal proportion" that occurs in certain shapes of nature with the characteristics of being harmonious, symmetrical and balanced. According to Ricketts, "you need to use auric proportions as they are attractive and remembered in the limbic as beautiful, harmonious and balanced system."
Objective: to compare facial auricle proportions in the edentulous patient without dentures and after rehabilitation with dentures.
Methods: we obtained data of 41 patients rehabilitated with total dental prostheses at the Clinic Department of Prosthodontics, University of Chile. They were photographed by the team of Cone beam computed volumetric tomography with facial scanning integrated and then measured and compared three facial proportions before and after rehabilitation with removable prosthesis, watching these ratios approaching or receding from the auric proportion. Statistical analysis of the data was performed using software STATA version 11. The tests Shapiro-Wilk and Student-T test were applied.
Results: in the facial proportion 1 before rehabilitation, was observed that 51.2 % of patients have auric proportion and after rehabilitation was obtained that 63.4 % had auric proportion. In the facial proportion 2 before rehabilitation, was observed that 22 % of patients had auric proportion and after rehabilitation was obtained that 17.1 % had auric proportion. In the facial proportion 3 before rehabilitation, was observed that no patient had auric proportion and after rehabilitation we found that 7.3 % had auric proportion.
Conclusions: in this sample shows a significant change in facial proportions found before and after prosthetic rehabilitation in the elderly patients. Proportion external angle of the eye Stomion in proportion to Stomion Menton is showing closer to the auric ratio before and after rehabilitation with dentures.
