To quantify and localise differences in Class I and Class II dental arches in Malay schoolchildren.
The subjects were 50 Malay schoolchildren (Mean age: 15 + 0.7 years) with either Class I (N = 25) or Class II (N = 25) malocclusions. Fourteen homologous landmarks on the upper and lower study models of the subjects were digitised using MorphoStudio software, and the Procrustes means were computed. The mean Class I and Class II configurations were subjected to
Normalised upper arch Class I and Class II configurations were statistically different (
Size and shape differences between Class I and Class II dental arches can be identified with finite element analysis.
