Embodiment Construction

[0020] As shown in the figure, a locking plate self-ligating bracket for orthodontics of the present invention includes a base plate 1 , a bracket body 2 and a movable locking plate 3 . The base plate is a mesh bottom base plate. The bracket body 2 has an archwire slot 5 , and the working wing 21 and the working wing 22 are respectively located on the left and right sides of the archwire slot 5 . A traction hook can be set on any working wing. A chute 6 is arranged on the working wing 22 , and at least two extruding rollers 4 protrude from the bottom surface of the chute 6 . The lower surface of the corresponding movable locking piece 3 is provided with a locking blind hole 33 cooperating with the extruding roller, and the movable locking piece 3 cooperates with the chute 6 to slide. The extruding roller 4 has elasticity, that is, when the movable locking piece 3 is pushed from the chute, the two squeezing rollers 4 can be pushed down by the movable locking piece 3 and squee...

Abstract

The invention relates to a bracket for tooth orthodontics, and specifically discloses a lock plate type self-ligating bracket for tooth orthodontics. The lock plate type self-ligating bracket comprises a substrate plate, a bracket body and a movable lock plate, wherein an arch wire groove is formed in the bracket body, work wings are respectively arranged on two sides of the arch wire groove, the work wing on one side of the arch wire groove is provided with a chute, at least two elastic extrusion rolling shafts are arranged on the groove bottom of the chute in a protruding manner, and the corresponding lower surface of the movable lock plate is provided with a locking blind hole matched with the extrusion rolling shafts. The lock plate type self-ligating bracket has the advantages that the movable lock plate slides smoothly, and locking and unlocking of the movable lock plate are convenient and rapid.

Description

technical field [0001] The invention belongs to the field of orthodontics, in particular to a self-locking bracket for orthodontics. Background technique [0002] Brackets for correcting occlusal deformities are important components in the orthodontic treatment of patients with occlusal deformities. In the traditional ligation method, the friction between the arch wire and the bracket is relatively large, which will affect the movement of the teeth. In order to improve the above situation, self-locking brackets have appeared on the market. Self-locking brackets reduce the friction between the arch wire and the bracket to a certain extent, and at the same time reduce the chairside operation time of the dentist. [0003] However, the existing self-locking brackets have a relatively complicated self-locking method, and are even prone to loosening after locking. Contents of the invention [0004] Aiming at the problems existing in the background technology, the present inven...
