The maxillary protraction device comprises a hyrax provided with an adjustable screw and a plurality of bands connected to the hyrax through a connecting wire. A tongue plate is connected to the hyrax through the connecting wire. A tongue sprue wire is provided and soldered to an anterior segment of a premolar band to reinforce the tongue plate. The connecting wire holds the tongue plate in a position to resist a tongue pressure. The physiological tongue forces produced during swallowing are used to move the maxilla in forward, sagittal and vertical directions. The parasagittal osteotomy is employed to reposition the individual segments in a widened transverse dimension, and to facilitate 3-dimensional movements of the maxilla.
