ABSTRACT

Objective: The aim of this study was to make soft-tissue esthetic evaluation in Chinese adults with well-balance profiles by Holdaway analysis and compare them with other ethnic population. Methods: Cephalometric radiographs of 100 selected Chinese adults with normal occlusion were analyzed; and with double selection by orthodontist and the public, a sample with 56 subjects of esthetically pleasing subjects was selected. All of them analyzed by the Holdaway cephalometrics conducted statistical test with SPSS program. Results: The Chinese esthetically pleasing subjects showed significant differences by gender in soft tissue subnasale to H line; significant statistical differences existed in most of measurements compared with Japanese, Yemeni and the Whites. Find out the correlational relationship in Holdaway cephalometric measurments and regression relationship of between the relevant hard and soft tissue. Conclusions: Holdaway norms in Chinese adults with well-balance profile were established. The regression relationships between the relevant hard and soft tissue were found out. Chinese had more convex profiles than the Yemeni and the Whites which were similar with Japanese, and showed the most markedly lip protrusion among the four ethnic population. These racial differences had to be considered in orthodontic treatment and orthognathic surgery planning.
