Study of growth pattern of cranialfacial complex based on skeletal age in children with normal occlusion in Shandong province

Abstract

Abstract: PURPOSE: To establish the normal values of cephalometric items for children with normal occlusion in Shandong province, and study the growth tendency of them and analyze the characteristics in different skeletal stages and sexes. METHODS: Lateral cephalograph was taken in 172 children of Han nationality with normal occlusion in Shandong province. The pictures were processed by WinCeph7.0, and statistical analysis was carried out using SPSS18.0 software Package. The results between sexes and 4 skeletal stages were compared. RESULTS: Facial contour in males were larger than in females. With growth of children, counter-clockwise rotation happened in mandibular plane, and males rotated more than females. Maxillary anterior tooth tilted more forword in males than in females, while mandibular anterior tooth positioned more upright in males than in females, and the protrution of maxillary and mandibular anterior tooth in males decreased along with growth. The lower lip in males was thicker than in females. CONCLUSIONS: The normal values and standard deviations of measuring items in different gender and bone-age group were established.
