Outcome Measures

Primary Outcomes (1)

  • Cephalometric angles and clinical features

    At least 6 months

Study Arms (2)

Group A

EXPERIMENTAL
Device: Fixed Tongue Appliance

Group B

EXPERIMENTAL
Device: Fixed Face Mask

Interventions

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.

Also known as: tongue plate
Group A

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.

Also known as: face mask
Group B
