Description

Technical Field

[0001] This utility model belongs to the field of orthodontic technology, specifically relating to a circular three-winged double-wire orthodontic device. Background Technology

[0002] In orthodontic treatment, the bracket device is the core component for realizing three-dimensional tooth movement. In the existing technology, traditional brackets mostly adopt a ligation structure, which uses metal wires or elastic ligatures to fix the archwire in the bracket groove. In recent years, self-ligating brackets have gradually become popular. They achieve quick locking of the archwire through sliding doors or spring clips, reducing the number of ligation steps.

[0003] However, existing bracket devices still have significant limitations. Traditional bracket slots can only provide archwire positioning in one direction, making it difficult to adapt to complex changes in dental arch shape, resulting in uneven distribution of orthodontic force. Summary of the Invention

[0004] The purpose of this invention is to provide a circular three-winged dual-wire orthodontic device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circular three-wing bifilar orthodontic device, comprising:

[0007] A base having a base plate for fixed connection with a tooth surface, the upper surface of the base plate being provided with a mesh retention structure;

[0008] The bracket body is fixedly installed on the top of the base, and guide rails extending vertically are symmetrically arranged on both sides of the top of the bracket body;

[0009] The bracket door is slidably disposed on the top of the bracket body, and its inner side is provided with a sliding groove that cooperates with the guide rail, so that the bracket door can slide relative to the bracket body in the direction of the cheek tongue;

[0010] A pair of hook grooves are symmetrically opened on the near, far and middle side walls of the bracket body, and the hook grooves have a U-shaped concave structure;

[0011] The main bracket groove is formed between the inner wall of the bracket door in the closed state and the top surface of the bracket body. Its groove extension direction is adapted to the curvature of the dental arch and is used to accommodate the orthodontic archwire.

[0012] The secondary support groove is disposed between the bottom surface of the support body and the top surface of the base, and the cross-section of the secondary support groove is semi-circular.

[0013] Preferably, the inner wall of the main support groove is provided with a nanocomposite coating, which contains zirconium dioxide particles and antibacterial silver ions.

[0014] Preferably, the groove of the secondary support is embedded with a shape memory alloy wire, and the deformation temperature of the shape memory alloy wire is 35-38℃.

[0015] Preferably, the slotted door has an integrated self-locking structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) Through the adaptive groove design of the main bracket groove along the arch curvature, combined with the memory alloy wire embedded in the groove of the secondary bracket, dynamic deformation pressure can be generated at oral temperature, forming a three-dimensional controllable orthodontic force system, avoiding the root resorption or tilting and displacement problems caused by traditional uniaxial orthodontics.

[0018] (2) The self-locking structure of the bracket door and the concealed ligation design of the U-shaped hook grooves on the mesial and distal sides avoid the mechanical stimulation of soft tissue by the traditional exposed ligation wings. Combined with the streamlined contour of the whole device, it significantly reduces oral mucosal damage and food impaction, and improves the patient's wearing comfort. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 and Figure 2 As shown, a circular three-winged bifilar orthodontic device includes:

[0024] The base 10 has a base plate 11 for fixed connection with the tooth surface, and the upper surface of the base plate 11 is provided with a mesh retention structure.

[0025] The bracket body 20 is fixedly installed on the top of the base 10, and guide rails extending vertically are symmetrically arranged on both sides of the top of the bracket body 20.

[0026] The bracket door 30 is slidably disposed on the top of the bracket body 20, and its inner side is provided with a sliding groove that cooperates with the guide rail, so that the bracket door 30 can slide relative to the bracket body 20 along the cheek tongue direction;

[0027] A pair of hook grooves 40 are symmetrically opened on the near, far and middle side walls of the bracket body 20, and the hook grooves 40 have a U-shaped concave structure.

[0028] The main bracket groove 50 is formed between the inner wall of the bracket door 30 in the closed state and the top surface of the bracket body 20. Its groove extension direction is adapted to the arch curvature of the dental arch and is used to accommodate the orthodontic archwire.

[0029] The secondary support groove 60 is disposed between the bottom surface of the support body 20 and the top surface of the base 10, and the cross-section of the secondary support groove 60 is semi-circular.

[0030] In one embodiment of the present invention, the inner wall of the main support groove 50 is provided with a nanocomposite coating, which contains zirconium dioxide particles and antibacterial silver ions.

[0031] In one embodiment of this utility model, a shape memory alloy wire is embedded in the groove 60 of the secondary support, and the deformation temperature of the shape memory alloy wire is 35-38℃.

[0032] In one embodiment of this utility model, the slotted door 30 has an integrated self-locking structure inside;

[0033] The device includes an elastic arm extending longitudinally along the inner sidewall of the tray door, with its root connected to the tray door via a hinge shaft; a locking block located at the free end of the elastic arm, with a wedge-shaped locking surface on its bottom surface that mates with the groove wall of the main tray; and an unlocking button protruding from the outer surface of the tray door and linked to the elastic arm. When the tray door is closed, the wedge-shaped locking surface of the locking block is embedded in the limiting recess of the sidewall of the main tray groove, forming a three-point contact locking mechanism.

[0034] As can be seen from the above, the base plate 11 of the base 10 is first fixedly connected to the tooth surface with dental adhesive, and its mesh retention structure is used to enhance the bonding stability. Then the bracket body 20 is vertically installed on the top of the base 10.

[0035] In the closed state, the inner wall of the bracket gate 30 and the top surface of the bracket body 20 form the main bracket groove 50. The main bracket groove 50 is opened and closed by manually sliding the bracket gate 30. The orthodontic archwire is embedded in the groove along the arch curvature and locked in position by the integrated self-locking structure. At the same time, the U-shaped hook groove 40 helps to fix the ligature wire or elastic chain ring. The secondary bracket groove 60 is equipped with a shape memory alloy wire that generates deformation pressure at oral temperature to assist in the positioning of the archwire. The nano-composite coating on the inner wall of the main bracket groove 50 continuously releases antibacterial components. Finally, three-dimensional orthodontic force control is achieved through the synergistic effect of the multi-level grooves.
