The invention provides to a prefabricated appliance for correcting many types of malocclusions typically with no more than limited use of wires or bands. The appliance is designed to be fitted stably and tightly to the upper front teeth or back teeth when needed. The appliance comprises: a teeth engaging box adapted to engage the upper front teeth; a stabilizing segment attached to the teeth engaging box and adapted to permit a stable and comfortable fitting of the appliance in a patient's mouth; and a pair of spaced inclined remodeling segments extending from in front of the teeth engaging box downward and rearward at a predetermined angle designed so that the inclined remodeling segments contact the lingual contacting surface of selected lower front teeth and urge the lower jaw forward and upward to the desired degree. |
