Me仇ods: 30 children patients (age 弘II ) and 44 adult patients (age 1弘21) of Cla.o;s 皿 malocclusion wi由 different vertical skeletal facial profile were recruited into the research , which were marked and analyzed by computer aided Delai陀 cephalometric analysis. Hypothesis testing was analyzied hy SAS9.0 , and independent-samples t-test were used ωanalyze the data when homogeneity of variance , while Satterthwaite t-test were used to analyze 由e data when variance ar由ythmias. Results: 白le Delaire cephalometric values of these samples were obtained ，由e difference of L2 , L4 , (p阳-M)/C2 ， (M-Cp)/C3 (%).
