N2  - Aim: To evaluate the dentoalveolar and skeletal effect of a new Infra-zygomatic Mini implant supported appliance and compare it with high pull headgear appliance in treatment of growing patients with class II malocclusion. Methodology: 22 growing boys aged between (10 to 12 years) with class II div 1 malocclusion randomly divided to 2 equal groups. The first group treated with high pull headgear with acrylic splint and the second one treated with a new Infra-zygomatic Mini implant supported appliance. The treatment duration was 8 months for both groups. Lateral cephalometric radiographs were taken before and after the treatment for each patient to be analyzed. Results: The first molar distalization was 2.58 ± 2.31 mm in head gear group and 1.53 ± 2.83 mm in mini-implants group. SNA and A-S VRL changed by mean (-0.29 ± 1.12 and -1.45 ± 2.19) respectively in the head gear group and by mean (-0.90 ± 0.63 and -0.66 ± 1.44) respectively in the mini-implants group. There were no significant differences between the two groups except in U1-PP, Cen U1-S-VRL,Interincisal angle and Nasolabial angle. Conclusions: the mini-implant supported appliance can be used as the fixed replacement of the removable high pull headgear appliance with no need for patient cooperation
