[Abstract] PURPOSE: To evaluate the difference of treatment on growing patients with Class Ⅱ division  using various
anteroposterior and vertical skeletal dysplasias MEHODS Twenty eight moderate to severe Class Ⅱ division 
malocclusion patients with Class Ⅰmolar and canineocclusion after treatment were selected The subjects were divided
into 3 groups based on the initial ANB and FMA angles Pretreatment and posttreatment cephalograms were evaluated
for soft and hard tissues changes after treatment The data was analyzed using SPSS 12 software package RESULS
ANB angle decreased in all three groups Changes of ANB angle in group 2 and group 3 were greater than group 1 ( P<
). SNA angle decreased significantly in group 3 (P<.. SNB angle increased significantly in group  (P<0.0 and
group 2(P<0.05. All groups had great maxillary incisors retraction and similar changes in mandibular incisor positions.Soft
tissue index showed no significant difference among three groups before and after treatment ( P>0.05. But nasolabial angle
(P<0.05, soft tissue convexity(P<0.05 and Z angle(P<0.0 changed significantly in group 3. CONCLUSIONS Conventional
orthodontic therapy successfully corrects Class Ⅱ division  malocclusions in growing patients with the improvement of soft
and hard tissues.The patients who initially have the most severe skeletal dysplasias can have the greatest changes in profile.
