Abstract:
An orthodontic bracket having a bracket pad (2), and a bracket body (1) extending from the bracket pad. The bracket has a slot (4) for receiving an orthodontic archwire. The slot has a proximal slot side face (4a), a distal side face (4b) and a slot ground face (4c). The bracket has at least one archwire support structure (5a, 5b) that forms a support surface (6a, 6b) in a plane of the slot ground face. The support surface is spaced from the slot ground face. The archwire support structure forms a flat and protrudes in a dimention generally parallel to a slot cross axis. The invention help maximizing the tip control in an orthodontic treatment.
