Dr. Kinya Fujita is a pioneer of lingual bracket system. 1978, he reported about development of the lingual bracket. In the recent Fujita method, tooth axis can be controlled precisely, with maximum utilization of its occlusal slot and horizontal slot. The occlusal slot, which is the main slot, provides precise rotation control and make it possible to place and remove arch wires from occlusal side. The horizontal slot can be used for auxiliary purposes and it provides precise tipping control.
