• Age: 7 Years – 15 Years
• Healthy volunteers: Accepted

Summary

The aim of the study is to compare an Infra-zygomatic Mini implant supported appliance with headgear in distalization and intrusion of maxillary dentition for treatment of growing patients with class II malocclusion (maxillary excess)

Detailed description

In this randomized trial, 2 groups will be included. The first group will receive an Infra-zygomatic Mini implant supported appliance. In the second group, the patient will receive a removable high pull headgear. the follow-up period will be 8 months or till class I canine or incisors relation is obtained. the assessment will be through a lateral cephalogram

Conditions

• Class II Division 1 Malocclusion

Interventions

Type	Name	Description
DEVICE	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
DEVICE	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
