Comparative Results of Maxillary Deficiency Treatment by Fixed Tongue Appliance and Fixed Facemask in Growing Patients

This Study is to Apply the Tongue Force to Correct the Dentofacial Deformities

A new fixed appliance will be used to transfer the tongue force during its physiological activity to advance the nasomaxillary complex; this method will be compared with the traditional method which uses a facemask with a fixed appliance in the mouth.

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

Inclusion Criteria:
