A study of hard tissue and soft tissue contour and growth on normal occlusion among Chinese population was made by means of computerized radiographic cephalometrics. Correlation analysis and polygon methods were applied to analyse the profile contour. The result showed that the dento-skeletal pattern and integumental contour were not necessarily alike, the diversity could be quite prominent. As to the growth change features in soft-tissue and hard-tissue structure, we found that the growth behavior of the lips seemed to show a tendency to follow the dental structure directly. The bony profile tended to become less convex with aging, while the soft-tissue profile remained stable in its degree of convexity.
