Description

Technical Field

[0001] This application relates to the field of medical devices, and particularly to an orthodontic bracket. Background Art

[0002] When an orthodontic bracket is bonded to a tooth, an operator applies an adhesive to the tooth surface and then places the bracket base of the orthodontic bracket on the adhesive so that the adhesive can bond the bracket base to the tooth, and further enables the adhesive to bond the tooth and the orthodontic bracket.

[0003] When an orthodontic bracket is bonded to a tooth through an adhesive, the excess adhesive will overflow from the bonding area between the orthodontic bracket and the tooth. However, in the prior art, the ligation wing is substantially parallel to the lowest point of the bracket base. When it is necessary to remove the excess adhesive, the operator's line of sight will be affected by the ligation wing, resulting in a longer time to remove the excess adhesive and reducing the bonding efficiency between the orthodontic bracket and the tooth. Summary of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the purpose of this application is to provide an orthodontic bracket with a relatively high bonding efficiency between the orthodontic bracket and the tooth.

[0005] To achieve the above purpose, the following technical solutions are adopted in this application:

[0006] An orthodontic bracket includes a bracket body, a bracket base, and an arch wire. The bracket body includes a slot groove. The bracket base is connected to the bracket body. The arch wire is disposed in the slot groove. The bracket body includes a bracket wing, and the bracket wing is connected to the slot groove. Define a projection plane perpendicular to the width direction of the orthodontic bracket. The projections of the bracket base and the bracket wing on the projection plane are projection surfaces, and the included angle formed by the lowest point of the bracket base and the lowest point of the bracket wing on the projection surface is greater than or equal to 2° and less than or equal to 8°.

[0007] Further, the included angle formed by the lowest point of the bracket base and the lowest point of the bracket wing on the projection surface is greater than or equal to 3° and less than or equal to 7°.

[0008] Further, the included angle formed by the highest point of the bracket base and the highest point of the bracket wing on the projection surface is greater than or equal to 0° and less than or equal to 5°.

[0009] Further, the included angle formed by the highest point of the bracket base and the highest point of the bracket wing on the projection surface is greater than or equal to 1° and less than or equal to 4°.

[0010] The orthodontic bracket provided by this application enables an operator to quickly remove the excess adhesive, thereby improving the bonding efficiency between the orthodontic bracket and the tooth. Brief Description of the Drawings

[0014] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present application.

[0015] As Figure 1 shown, an orthodontic bracket 100 includes a bracket body 11, a bracket base 12, and an arch wire 13. The bracket base 12 is connected to the bracket body 11. The tooth is connected to the bracket body 11 through the bracket base 12. The bracket body 11 includes a slot groove 111. The arch wire 13 is disposed in the slot groove 111, so that the arch wire 13 can be disposed in the bracket body 11. The traction force provided by the arch wire 13 is transmitted to the tooth through the bracket base 12, so that the tooth can be displaced to a preset position, thereby achieving the purpose of orthodontic correction of tooth deformity. It should be noted that the preset position refers to the normal physiological position of the tooth. In the present application, it should be noted that the width direction of the orthodontic bracket 100 refers to the left-right direction as Figure 1 shown, the length direction of the orthodontic bracket 100 refers to the front-back direction as Figure 1 shown, and the height direction of the orthodontic bracket 100 refers to the up-down direction as Figure 1 shown.

[0016] As Figures 1 to 3As shown in the figure, specifically, the bracket body 11 includes a bracket wing 112 and a ligature loop. The bracket wing 112 is connected to the slot groove 111. When the orthodontic bracket 100 is in the ligated state, the bracket wing 112 is connected to the ligature loop. Define a projection plane 101 perpendicular to the width direction of the orthodontic bracket 100. The projections of the bracket base 12 and the bracket wing 112 on the projection plane 101 are the projection surfaces. The angle α formed by the lowest point of the bracket base 12 and the lowest point of the bracket wing 112 on the projection surface is greater than or equal to 2° and less than or equal to 8°. More specifically, the angle α formed by the lowest point of the bracket base 12 and the lowest point of the bracket wing 112 on the projection surface is greater than or equal to 3° and less than or equal to 7°. In this embodiment, the angle α formed by the lowest point of the bracket base 12 and the lowest point of the bracket wing 112 on the projection surface is greater than or equal to 4° and less than or equal to 6°. Through the above settings, when the orthodontic bracket 100 is in the ligated state, it can prevent the angle between the lowest point of the bracket base 12 and the lowest point of the bracket wing 112 from being too large, resulting in the ligature loop falling off from the first ligature wing, thereby improving the connection stability between the first ligature wing and the ligature loop. It can also prevent the angle between the lowest point of the bracket base 12 and the lowest point of the bracket wing 112 from being too small, which may block the operator's line of sight, so that the operator can quickly remove the excess adhesive to improve the bonding efficiency between the orthodontic bracket 100 and the tooth. In addition, it can also enable the operator to put the ligature loop into the first ligature wing at a faster speed, thereby improving the ligating efficiency of the orthodontic bracket 100. It should be noted that when the bracket base 12 is connected to the tooth through an adhesive, the excess adhesive will overflow from the connection between the bracket base 12 and the tooth.

[0017] As another implementation, the angle β formed by the highest point of the bracket base 12 and the highest point of the bracket wing 112 on the projection surface is greater than or equal to 0° and less than or equal to 5°. Specifically, the angle β formed by the highest point of the bracket base 12 and the highest point of the bracket wing 112 on the projection surface is greater than or equal to 1° and less than or equal to 4°. More specifically, the angle β formed by the highest point of the bracket base 12 and the highest point of the bracket wing 112 on the projection surface is greater than or equal to 2° and less than or equal to 3°. Through the above settings, it further prevents the operator's line of sight from being blocked, so that the operator can further quickly remove the excess adhesive to improve the bonding efficiency between the orthodontic bracket 100 and the tooth. In addition, it can also enable the operator to put the ligature loop into the first ligature wing at a faster speed, thereby improving the ligating efficiency of the orthodontic bracket 100.

[0018] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this application.
