Brief summary

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

Detailed 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

Interventions

DEVICEIntraoral protraction device

Use of modified lingual arch with indirect anchorage from screws between lower lateral incisor and lower canine to protract maxilla after ALT-RAMEC protocol

DEVICEExtraoral protraction device

Facemask which is an extraoral appliance used for maxillary protraction
