Intraoral Maxillary Protraction Technique vs Facemask Using Alt-RAMEC Protocol for Treatment Class III Growing Patients

Cairo University22 enrolled

Overview

The study compares use of intraoral technique for maxillary advancement and extra oral technique with hep of protocol called Alt-RAMEC which depends on repeated expansion and constriction of maxilla to help in maxillary protraction

Delivering hybrid expander supported by 2 miniscrews in palate to perform Alt-RAMEC protocol for 9 weeks then intervention group will start protraction using class iii elastics on modified lingual arch with hooks in canine area and 2 miniscrews labially between lower lateral and canine while control group use face mask for protraction of maxilla
