Cephalometric study of craniofacial morphology by computer on children with normal occlusion in chongqing.

Objective:In order to establish the normal value of hard tissues of Chongqing and to reveal the regular patterns and characteristics concerning the craniofaicial morphology. Method:58 students,with early permanent dentition were selected as the samples.The cephalometric images were scanned into a computer and the images were impoerted into the program.The cephalometric analysis were automated by the computer.The cephalometric analytical on hard tissues features was used in this study.Correlational analysis for SNA、SNB、ANB、FMA、FMIA、IMPA were caculated. Result:The normal values of hard tissues for early permanent dentition on normal occlusal children of Chongqing were established and compared with that of other areas. Conclusion:We found that hard cephalometric measurement values are various in sexual and races and regional population.
