Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to an orthodontic bracket. Background Art
[0002] Orthodontic brackets include lingual orthodontic brackets and labial orthodontic brackets. A labial orthodontic bracket refers to installing the orthodontic bracket on the side of the tooth close to the lips. Fixed orthodontic correction with a labial orthodontic bracket is to cement the correction bracket to the buccal side of the tooth through an adhesive, and apply force through the correction arch wire and the correction bracket on the tooth to correct the teeth. However, during the correction period, there is an obvious hindrance to the patient's appearance.
[0003] A labial orthodontic bracket is to paste devices such as orthodontic brackets on the inner side of the teeth. Since the lingual orthodontic bracket is all installed on the lingual side of the tooth for treatment, during daily conversations, outsiders cannot see the brackets and arch wires at all, thus achieving the effect of "invisible" orthodontic treatment.
[0004] An orthodontic traction hook is added to the arch wire, and a special tool can be used to clamp the traction hook on the arch wire, so that the gap can be closed by the traction force of the arch wire.
[0005] During the treatment of patients, traction hooks of different lengths are required to close the gaps. However, in the prior art, usually only one traction hook is provided. When the patient needs to use traction hooks of different lengths, the operator needs to remove the traction hook from the arch wire and replace it with a new one, which prolongs the time of tooth correction and thus reduces the efficiency of tooth correction. Summary of the Utility Model
[0006] In order to solve the deficiencies of the prior art, the purpose of this application is to provide an orthodontic bracket with relatively high correction efficiency.
[0007] To achieve the above purpose, the following technical solutions are adopted in this application:
[0008] An orthodontic bracket, which includes a bracket body. The bracket body is connected to the bracket base. An arch wire is arranged in the bracket body. The arch wire includes an arch wire body and a traction assembly. The arch wire body is connected to the traction assembly, and the traction assembly can be arranged at any position on the arch wire body. The traction assembly includes a first traction hook, a second traction hook and a third traction hook, and the first traction hook, the second traction hook and the third traction hook are arranged in sequence away from the arch wire body.
[0009] Further, the distance between the first traction hook and the arch wire body is greater than or equal to 0.8 mm and less than or equal to 1.5 mm.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.
[0023] As Figure 1As shown in the figure, an orthodontic bracket 100 includes a bracket body 11, a bracket base 12, and an arch wire 13. The bracket base 12 is used to adhere to the teeth, the bracket body 11 is used to fix the arch wire 13, and the arch wire 13 is used to provide traction force. The bracket body 11 and the bracket base 12 are connected, and the arch wire 13 is arranged inside the bracket body 11. Through the above settings, the traction force provided by the arch wire 13 can be transmitted to the teeth through the bracket body 11 and the bracket base 12, so that the teeth can move to the preset position through the traction force of the arch wire 13, thereby realizing orthodontics. It should be noted that the preset position refers to the normal physiological position of the teeth.
[0024] As Figure 2 shown in the figure, specifically, the arch wire 13 includes an arch wire body 131 and a traction assembly 132. The arch wire body 131 and the traction assembly 132 are connected, and the traction assembly 132 can be arranged at any position of the arch wire body 131. Through the above settings, the operator can judge the position where the traction assembly 132 needs to be placed according to the actual situation, so as to place the traction assembly 132 at the corresponding position.
[0025] As Figures 2 to 3 shown in the figure, more specifically, the traction assembly 132 includes a first traction hook 1321, a second traction hook 1322, and a third traction hook 1323. The first traction hook 1321, the second traction hook 1322, and the third traction hook 1323 are arranged in sequence away from the arch wire body 131. Through the above settings, the operator can choose to connect an elastic structure such as a chain to the traction assembly 132 and the orthodontic bracket 100 according to the actual situation to close the space between the teeth and close the dental gaps. It can also enable the operator to connect the traction assembly 132 and the orthodontic bracket 100 through an elastic structure such as a chain without replacing the traction assembly 132, thereby reducing the time of tooth correction and improving the efficiency of tooth correction.
[0026] In this embodiment, a curve extending along the direction of the hard palate 200 is defined, and the first traction hook 1321, the second traction hook 1322, and the third traction hook 1323 are arranged along the curve. Among them, the hard palate 200 refers to the anterior 2 / 3 of the palate, and its bony basis is the palatine process of the maxilla and the horizontal plate of the palatine bone. Through the above settings, the extending directions of the first traction hook 1321, the second traction hook 1322, and the third traction hook 1323 are consistent with the trend of the hard palate 200, which can improve the comfort of the patient.
[0027] As Figures 2 to 4As an implementation, the distance L1 between the first traction hook 1321 and the arch wire body 131 is greater than or equal to 0.8 mm and less than or equal to 1.5 mm. Specifically, the distance L1 between the first traction hook 1321 and the arch wire body 131 is greater than or equal to 0.9 mm and less than or equal to 1.4 mm. More specifically, the distance L1 between the first traction hook 1321 and the arch wire body 131 is greater than or equal to 1 mm and less than or equal to 1.3 mm. Through the above settings, it is possible to prevent waste of the material of the traction hook due to the excessive length of the distance L1 between the first traction hook 1321 and the arch wire body 131, thereby improving the structural compactness of the traction assembly 132. It is also possible to prevent the elastic structure such as the elastic chain from being unable to connect to the first traction hook 1321 due to the too short distance L1 between the first traction hook 1321 and the arch wire body 131, thereby improving the practicability of the first traction hook 1321.
[0028] As an implementation, the distance L2 between the second traction hook 1322 and the arch wire body 131 is greater than or equal to 1.8 mm and less than or equal to 3 mm. Specifically, the distance L2 between the second traction hook 1322 and the arch wire body 131 is greater than or equal to 2.1 mm and less than or equal to 3.2 mm. More specifically, the distance L2 between the second traction hook 1322 and the arch wire body 131 is greater than or equal to 2.4 mm and less than or equal to 2.9 mm. Through the above settings, it is possible to prevent waste of the material of the traction hook due to the excessive length of the distance L2 between the second traction hook 1322 and the arch wire body 131, thereby improving the space utilization rate of the traction assembly 132. It is also possible to prevent the elastic structure such as the elastic chain from being unable to connect to the second traction hook 1322 due to the too short distance L2 between the second traction hook 1322 and the arch wire body 131, thereby improving the practicability of the second traction hook 1322.
[0029] As an implementation, the distance L3 between the third traction hook 1323 and the arch wire body 131 is greater than or equal to 2.5 mm and less than or equal to 4.8 mm. Specifically, the distance L3 between the third traction hook 1323 and the arch wire body 131 is greater than or equal to 2.9 mm and less than or equal to 4.4 mm. More specifically, the distance L3 between the third traction hook 1323 and the arch wire body 131 is greater than or equal to 3.3 mm and less than or equal to 4 mm. Through the above settings, it is possible to prevent waste of the material of the traction hook due to the excessive length of the distance L3 between the third traction hook 1323 and the arch wire body 131, thereby improving the material utilization rate of the traction assembly 132. It is also possible to prevent the elastic structure such as the elastic chain from being unable to connect to the third traction hook 1323 due to the too short distance L3 between the third traction hook 1323 and the arch wire body 131, thereby improving the practicability of the third traction hook 1323.
[0030] As an implementation, the traction assembly 132 further includes a connection structure 1324. The connection structure 1324 is connected to the first traction hook 1321 and the connection structure 1324 is connected to the arch wire body 131, so as to improve the connection stability between the traction assembly 132 and the arch wire body 131.
[0031] Specifically, the connection structure 1324 includes a connection body 1324a and a recessed portion 1324b. The connection body 1324a is connected to the recessed portion 1324b, and the arch wire body 131 is disposed within the recessed portion 1324b. Through the above arrangement, the integrity between the connection structure 1324 and the arch wire body 131 can be improved, and further the connection stability between the connection structure 1324 and the arch wire 13 is improved. In addition, the integral setting of the connection structure 1324 and the arch wire 13 can also improve the comfort of the patient.
[0032] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
