　　Objectives: To determine and analyze the incisal jaw morphology of maxillary bone of class II division 1 malocclusion among different vertical skeletal facial types.Materials and methods: 121 subjects of pretreatment lateral cephalometric radiographs with class II division 1 malocclusion including 54 males and 67 females of early permanent dentition aged from 12-14 years were studied. SN-MP angle was used to select 59 average angle, 30 high angle and 32 low angle vertical skeletal facial types C...
