The present study was designed to formulate cephalometric norms of normal occlusion for usage in orthodontic diagnosis of malocclusion in Korean children. Thirty two children, aged 4 to 6. with normal occlusion were chosen for this study. Sagittal and vertical relations were analyzed using lateral cephapogram and clinical photos and the measurements were compared with those of adults. On skeletal sagittal analysis, the mean values of the SNA and SNB angles were 83°and 78.72°. It showed that the mandible was retrognathic and retropositioned in comparison to those angle pattern in children and reduction of gonial angle due to counterclockwise rotation of the mandible. On dental analysis. the mean values of the U1 to SN and IMPA were 91.04° and 86.57°, This showed retroclined upper and lower deciduous teeth in comparison to adults. For values. the linear values were generally greater in males than females.
