title: The cephalometric distinction of class II, division 2 malocclusion.
abstract: Forty-two cases of Class II, Division 2 malocclusions were selected on the basis of Strang's first six steps. There were nineteen male and twenty-three female patients in the study. The average age was 12.5 years. These cases were compared with the normal sample of the Alabama Analysis. The Class II, Division 2 sample was compared to a sample of fifty-seven Class II, Division 1 cases. Means, standard deviations, and analyses of covariance, adjusted for age and sex, were derived. Illustrations show, numerically and graphically, the similarities and differences between Class II, Division 2 malocclusions and normal occlusions. Fig. 4 shows the comparison between the Class II, Division 1 and the Class II, Division 2 typical profiles.
