RESUMO
The purpose of this study was to provide data on the normative values of some clinically important soft tissue dimensions for adult Korean females with aesthetically beautiful facial profiles. Lateral cephalograms of 18 Korean female models, who were selected for their well balanced and aesthetic facial profiles, were evaluated. All cephalograms were taken with the subjects in a natural head position with the teeth in occlusion and the lips at rest. The means and standard deviations were determined and presented. In addition, comparisons with the previous studies were performed. The results of the present study were as follows: 1. The upper and lower lips were posteriorly located in relation to the Ricketts' E line (Upper lip to E line: -2.08, Lower lip to E line: -0.04). 2. Both lips were more posteriorly located than those in the results of previous studies on Korean females selected by normal occlusion, but more anteriorly located than in the results of studies selected on an aesthetic basis. 3. The nasolabial angle for this sample was 101.03 degrees with a standard deviation of 8.47 degrees.
