About

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

Full description

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
