title: [A study on dental and cranioficial structure of normal shanghai adults occlusion-I the craniofacial structure analysis with posterioanterior cephalometric roentgenography]
abstract: OBJECTIVE: To evaluate the characteristics of normal transverse craniofacial structure in Shanghai area and to establish the database of normal Shanghai adults occlusion for posterioanterior cephalometric roentgenography.METHODS:Posterioanterior-cephalometric of the 92 adults subjects with normalocclusion were measured and analysed by Jiffy orthodontic evaluation 5.0 software package.RESULTS:The database of normal Shanghai adults occlusion for posterioanterior cephalometric roentgenography was established. Transverse measurements were intercorrelated, no statistically significant gender differences were demonstrated in craniofacial width, while the molar overjet of male was larger than that of female.CONCLUSION:The normal transverse cranioficial structure in Shanghai area has its own characteristics. The established database would provide a foundation for the diagnosis and treatment of malocclusion.
