Embodiment 1

[0048] according to figure 1 As shown, a self-ligating orthodontic bracket is provided, including:

[0049] The bottom plate 100 is used to adapt to the curvature of the surface of the crown and be bonded to the surface;

[0050] The main body 200 is provided with a groove 201 for accommodating the orthodontic wire and conducting the orthodontic wire to apply a correction force to the surface of the crown, and a clamping hole 202 for inserting the clip 300; the bottom plate 100 is away from the crown One side is welded to the bottom end surface of the main body 200;

[0051] A locking piece 400, which is slidably engaged with the upper end surface of the main body 200, so as to be slidably connected with the locking member 300 thereon;

[0052] Wherein, the opening direction of the groove 201 is upward.

[0053]During specific use, the side of the locking piece 400 facing away from the main body 200 is composed of an arc surface 401 and a plane 402 integrally formed with th...

Embodiment 2

[0060] A self-locking orthodontic bracket according to Embodiment 1, according to Figure 4 As shown, the side of the locking piece 400 facing the main body 200 is provided with a downwardly opening groove 403 for sliding connection with the clip 300 , and the left and right sides of the groove 403 are arranged symmetrically. There is a fixing part 404, so that the clamping part 300 is in sliding contact with the side wall of the fixing part 404;

[0061] Wherein, the fixing part 404 is composed of a limiting part 406 with an arc-shaped concave surface 405, and a sliding part 407 formed integrally with it, and the width between the opposite sides of the two sliding parts 407 is a gradual change from narrow to wide. configuration, and the narrow end is connected to the limiting part 406, so that when the clip 300 abuts against the arc-shaped concave surface 405, the locking piece 400 is engaged with the main body 200, and when an external force acts on When the locking piece 4...

Embodiment 3

[0065] According to a kind of self-locking orthodontic bracket described in embodiment three, according to Figure 5 As shown, the left and right sides of the locking piece 400 are symmetrically provided with sliders 408 for slidingly connecting with the main body 200 .

[0066] More specifically, according to figure 2 , image 3 As shown, the end of the main body 200 facing the locking piece 400 is provided with a sliding platform 203 that is slidably adapted to the locking piece 400. groove 201 and sliding groove 205, the bottom end surface of the cover opening groove 204 is flush with the bottom end surface of the sliding groove 205 and connected through the groove 201, the bottom end surface of the groove groove 201 is located at the bottom end surface of the opening cover The groove 204 is below the bottom end surface of the sliding groove 205, so that after the orthodontic wire is placed in the groove 201, it is locked and fixed with the main body 200 through the lock...

Abstract

The invention provides a self-locking orthodontic bracket, which comprises a bottom plate used for being matched with the surface radian of a dental crown and being adhered to the surface of the dental crown; a main body is provided with a groove and a clamping hole, the groove is used for accommodating an orthodontic wire and transmitting the orthodontic wire to apply orthodontic force to the surface of the dental crown, and the clamping hole is used for placing a clamping piece; one surface, deviating from the dental crown, of the bottom plate is welded on the bottom end surface of the main body; a locking plate is clamped on the upper end surface of the main body in a sliding manner so as to be connected with the clamping piece on the main body in a sliding manner; and the opening direction of the groove is upward. Theself-locking orthodontic bracket has the advantages that the defect that locking between the locking plate and the main body is not firm can be effectively overcome, the self-locking function is strong, and due to the structural characteristics of the self-locking orthodontic bracket, automatic unlocking cannot occur when hard food is eaten in the using process, so that the situation that human bodies are injured due to separation of the locking plate is avoided, and the safety and the stability of the structure protected by the invention are improved while the functionality of the structure is ensured.

Description

technical field [0001] The invention relates to the technical field of dental orthodontics, in particular to a self-locking orthodontic bracket and a preparation method thereof. Background technique [0002] The orthodontic bracket is an important part of the fixed orthodontic technology. It is directly bonded to the surface of the crown with an adhesive. Its main function is to fix the arch wire. The arch wire exerts various types of orthodontic force on the tooth through the orthodontic bracket. , so as to control the three-dimensional movement of teeth to achieve the purpose of orthodontic treatment. [0003] And the orthodontic bracket of existing structure is because of its structural defect, makes edible hard food in the oral cavity, is easy to clamp thrust to push it away on the cleat on it in the process of mastication, opens orthodontic wire with cleat Going out, even the cleats are dropped and swallowed by mistake, causing harm to the human body. [0004] Orthodo...
