Arms Assigned Interventions
Experimental: Group A Device: Fixed Tongue Appliance
A functional appliance used for maxillary protraction. It has two bands on first molars, expansion screw and long palatal plate in the canine area which cages the tongue and transfers the force of the tongue during physiological activity to the upper arch.
Other Name: tongue plate
Experimental: Group B Device: Fixed Face Mask
An extra-oral appliance used for treatment of maxillary deficiency in growing patients. It takes anchorage from the chin and forehead, has a fixed intra-oral appliance with an expansion screw and hooks for elastics that exert a force of 300 gr. It should be used 14 hours a day.
Other Name: face mask

Detailed Description:

The above method will be compared with traditional one which uses the facemask in combination with an intra-oral fixed appliance.
