Abstract: Provided is an orthodontic buccal tube, which is capable of preventing glue from flowing out towards a boundary between a tooth (300) and a base (100), being firmly attached to a face of the tooth (300), and being easily removed from the face of the tooth (300) after being used. The orthodontic buccal tube is attached to the face of the tooth (300) by the glue (400), and includes a base (100) having a bonding face (110) on one side of the buccal tube, a body (200) having a slot (210) into which an archwire is inserted in the middle of the body (200) on a side opposite the base, and a glue anti-outflow step (120) formed along an outer circumference of the bonding face (110) at a predetermined height in a closed loop. The glue anti-outflow step (120) prevents the glue (400) applied to the bonding face (110) from flowing out towards a boundary between the base (100) and the tooth (300).

Abstract: Disclosed herein is an orthodontic bracket which can be firmly attached to a tooth surface and can also be easily detached from the tooth surface after having been used. The orthodontic bracket includes a plurality of channels formed in a bonding surface of a base. Each of the channels is formed such that it is long in a direction perpendicular to the slot, and is open at a first side surface thereof located at a side surface of the base. Long and short side surfaces of the channels are inclined to serve as a locking step when the orthodontic bracket is attached to the surface of the tooth.
