An orthodontic expansion device which may be used for expanding the palate of a patient or for other orthodontic treatments. The expansion device is a compact design which essentially uses tubular-shaped screw actuating structure and rod-shaped screw actuating structure for connecting first and second legs which are respectively attached to a patient's teeth. When at least one of the screw actuating structures is rotated, expansion of the legs may be effected during the treatment of a patient. The legs may be connected rigidly to the screw actuating structure or may form part of the screw actuating structure.
