Orthodontic bracket for tooth correction

Abstract

The orthodontic bracket comprises a bracket bottom plate, a locking groove, a locking wing and a lock catch, the center of the bottom surface of the bracket bottom plate is provided with a circular concave surface, the periphery of the circular concave surface is provided with a plurality of radial linear grooves, and the circular concave surface is provided with a plurality of undercut nail protrusions; a lock wing is arranged on the back surface of the bracket bottom plate, a lock groove is formed in the middle of the lock wing, and the lock wing is divided into an occlusal direction wing and a gingival direction wing by the lock groove; the occlusal direction wing is composed of two cambered surfaces with gradients, a lock catch is installed in the middle of the gingival direction wing in a sliding mode, and a traction hook is installed at the end of the lock catch. According to the invention, the integral structure design of the towing hook and the lock catch and the double-gradient cambered surface design of the occlusal direction wing are adopted, so that the overall thickness of the appliance is effectively reduced; meanwhile, a plurality of radial linear grooves are formed in the circular concave surface, so that the effective colloid is in wider contact with the bottom plate, and the bonding force of the orthodontic bracket is obviously enhanced.

Description

technical field [0001] The invention relates to an orthodontic bracket used for orthodontic treatment, belonging to the technical field of medical instruments for orthodontic treatment of teeth. Background technique [0002] As we all know, during teething, children often have individual dental deformities, complete dentition deformities, etc. due to many factors, and even seriously affect the facial appearance and the ability to eat and chew, so corrections are needed; in addition, there are many adults. Patients with malocclusion also have a large demand for orthodontic treatment. Therefore, the invention and innovation of orthodontic appliances are particularly important in the development of orthodontic medical field in my country and even in the world. [0003] At present, there are many types of fixed metal bracket appliances for orthodontics, such as square wire bracket appliances, straight wire bracket appliances, self-locking bracket appliances, etc. has produced ce...

AI Technical Summary

Problems solved by technology

[0004] 1. After bonding for a period of time, the bottom plate of the appliance is prone to fall off. The reason is due to the structural defects of the bracket bottom plate itself. Specifically, the bracket itself is relatively thick, and the occlusal occlusal relationship is too tight. However, occlusal disengagement is prone to occur under strong chewing and occlusal force; secondly, the bottom plate of the bracket is not designed to facilitate the gas discharge after the colloid is pressed, so that the effective bonding colloid solution is too little bonded to the bottom plate, resulting in poor adhesion. decline

[0005] 2. The overall thickness of the appliance is relatively large, resulting in poor comfort for patients

[0006] 3. The traditional bracket adopts the locking wing design of the upper and lower single wings. Although it is very smooth in the clinic, the patient still feels that the four single wings hang the mucosa in the oral cavity, and occasionally the oral mucosa will be punctured.

[0007] 4. The existing traction hook needs to be fixed on the edge of the appliance, which increases the thickness of the bracket virtually. Once the thickness increases, the occlusal collision force will increase significantly, and the risk of falling off will increase.
