A low profile orthodontic bracket with arcwire slot (23). The slot (23) has a height (d1) between .0190 and .020 inches and a depth (d2) less than .026 inches, with a preferred embodiment being a height of .0195 inches and a depth of .025 inches. The slot is preferably rectangular in cross-sectional shape thus having equal length short sides and preferably equal length long sides (25),(26), the long sides having straight, uninterrupted walls. The orthodontic appliance may be in the form of a bracket or tube, each for receiving a .019 x .025 inch archwire and each shaped for one or more upper or lower permanent teeth. The appliances may be universal, thus being of a same size on all applicable teeth or may be a bi-dimensional setup, which uses conventional .018 or .022 inch slotted brackets in combination with the slotted bracket having a height between and not including .0190 and .020 inches.
