Abstract

The utility model discloses a dental orthodontic self-ligating bracket. The dental orthodontic self-ligating bracket comprises a base plate and a bracket body provided with an arch wire groove. A bracket opening is arranged at an intersection of the bracket body and the arch wire groove. Chutes formed by wire-electrode cutting are symmetrically arranged on both sides of the bracket opening. Chute sides are vertically arranged in the chutes. A bracket cover made of an elastic material is slidingly arranged in the chutes. Sliding bars are arranged on both sides of the bracket covers. A front wing hook and a back wing hook are respectively arranged at the front and back ends outside each sliding bar. Inclined groves are arranged at two sides of the starting end of the chute at the left side of the corresponding chute side along an insertion direction of the bracket cover. A flare groove is arranged at two sides of the tail end of each chute. The opening of each flare groove reduces gradually along the insertion direction of the bracket cover. The upper end faces of a part of each inclined groove and the flare groove are lower than that of the chutes. The bracket cover is just pushed to the end, and the wing hooks at the front and back ends of the bracket cover bend, and the three grooves are not in a same plane so that the bracket cover deforms elastically. Therefore, the dental orthodontic self-ligating bracket is self-ligated, and fussy operation of ligating steel wires is avoided.
