Kind Code:

Abstract:
The purpose of the present invention is to provide an orthodontic bracket in which a ligation member can be easily hooked, the ligation member can be prevented from being detached, and furthermore, friction at the time of movement of teeth can be suppressed. An orthodontic bracket (11) includes: a sheet-like base part (12) to be disposed such that the reverse surface (15a) side thereof opposes a tooth surface; a pair of protrusion parts (21a, 21b) protruding in the sheet thickness direction from the obverse surface (15b) side of the base part (12) in a state of being spaced apart from each other, so as to form a groove-like slot (22) for receiving therein an arch wire (44); and a pair of wing parts (31a, 31b) protruding from the pair of protrusion parts in outward directions. Hook grooves (36a, 36b) for inserting therein a ring (45), are formed between the upper surface of the base part and the reverse surfaces of the pair of wing parts. Hooking parts (28a, 28b) at inner sections of the hook grooves are positioned so as to be distant upward from the arch wire received in the slot.
