Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mini Implant Supported Appliance
this group will receive an Infra-zygomatic Mini Implant Supported Appliance after leveling and alignment of the four upper incisors for 8 months or till class I canine or incisors realation is reached with follow up every month
Infra-zygomatic Mini Implant Supported Appliance
1. leveling and alignment of the four maxillary incisors
2. infra zygomatic mini-implant will be placed bilaterally
3. wire frame work that is designed resembling the inner bow of headgear will be adapted to the upper arch
4. a heavy arch wire engaging the 4 incisors will be attached to the wire frame work
5. orthopedic force will be delivered from the mini-implants to the wire frame work
Headgear
this group will receive a high pull headgear appliance attached to a removable acrylic maxillary splint for 8 months or till class I canine or incisors realation is reached with follow up every month
high pull head gear
1. acrylic maxillary splint is made with flying tubes
2. high pull head gear is adapted to be inserted in the flying tubes
