Dental arch form in 5 Chinese minorities was metrically analyzed for the purpose of describing their dental arch form with the use of widths and lengths and showing their affinity to other Asian populations through the application of multivariate analysis. Materials were dental impression models of 5 Chinese minorities, Hani, Dai, Naxi, Pumi and Miao in Yunnan Province. They were placed under an arm-type 3D digitizer (Micro Scribe 3DX) and the landmarks were plotted. Arch width was represented by 9 parameters and arch length was represented by 8 parameters with the use of the program CADKEY2000. Principal component analysis showed that dental arch size of Yunnan Chinese minorities was small and relatively short compared with other Asian and Pacific populations in males and females. Among the 5 groups Hani had a larger dental arch, hereas Miao had a smaller one than the other groups. In the sex-combined analysis, it was generally clear that males arches were larger in size and broader in shape in all of the populations studied.
