简要总结
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)
详细描述
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
