Self-locking bearing groove with self-provided locking buckle of elastic ring on working wing

Abstract

The invention relates to a self-locking bearing groove with a self-provided locking buckle of an elastic ring on a working wing, which comprises a bottom plate of the bearing groove and a working wing arranged at the buccal labial face of the bottom plate of the bearing groove, wherein the working wing comprises a base connected with the bottom plate of the bearing groove, the middle part of the base is downwards recessed so as to form slots, and all the slots are arranged on the axis of one slot; the base is divided into a first base and a second base by the axis of the slot; the self-locking bearing groove with the self-provided locking buckle of the elastic ring on the working wing is characterized in that: the top of the first base is provided with a locking buckle of an elastic ring, the locking buckle of the elastic ring comprises a spring piece and a free end, one end of the spring piece is fixed with the first base, the other end is connected with the free end, the spring piece is a bending piece with elasticity, and the free end is suspended above the buccal labial face of the working wing; a clamping piece and a blocking piece which extend out towards different directions are arranged on the free end; and when the spring piece is at a loose state, the clamping piece, the blocking piece and the slots form an arch wire groove together. The clamping piece and the blocking piece are simultaneously and synchronously moved, so that the functions of closing an outlet / inlet port of an arch wire and restricting the arch wire in the arch wire groove are simultaneously realized.

Description

technical field

[0001] The invention relates to the field of dental orthodontic instruments, in particular to a self-locking bracket with an elastic ring lock on the working wing. Background technique

[0002] Orthodontic treatment is a highly specialized branch of dentistry, mainly for the correction of teeth, jaws, and facial deformities, and gradually restores the normal occlusal function of patients by fixing orthodontic appliances inside the oral cavity. Brackets are an important part of orthodontic appliances. They are mainly bonded to front teeth, canines, and premolars. Orthodontic treatment guides the misaligned teeth to move to the ideal position by installing the orthodontic arch wire in the groove of the bracket. s position.

[0003] The traditional brackets are fixed in the groove by ligating wires or elastic rubber rings, but this fixing method has the disadvantages of time-consuming and inconvenient clinical operation, high friction, and poor comfort. In rec...
