Objective:
The aim of the study was to establish a cephalometric normal standard value for Korean in Yanbian China by means of Steiner analysis.
Methods:
72 cases of Korean adults in Yanbian with normal occlusion were selected, standard lateral cranial X-ray films were taken and cephalometric Steiner analysis was performed. The data was compared with Korean in Soul of Republic of Korea with normal occlusion.
Results:
1) Cephalometric Steiner normal standard values, standard deviation and Cheveron analysis chart were established. 2) 1-NB angle of male was significantly bigger than that of female, while GoGn-SN angle of female was significantly bigger than that of male (P<0.05), respectively. 3) There were significant differences on SNA, SNB, ANB, SND, [symbol: see text]-NA (mm),1-NB (except woman) compared with same age group Korean presented by In-Chool Park (P<0.05).
Conclusion:
There is a significantly different between male and female Koreans with normal occlusions in Yanbian China. This experiment filled in the blank of stomatology research in Yanbian Korean autonomous region. In the mean while, it completed and supplemented the normal occlude data of different nations in China. The present paper also provided the reference for clinic and scientific research on orthognathic surgeon. At the same time, the experiment provided the evidence for the further research.
