Description

Technical Field

[0001] The utility model relates to the technical field of brackets, and more specifically, to a bracket with a firm bottom plate. Background Art

[0002] At present, most of the brackets used in domestic orthodontic treatments are composed of a bracket body and a base plate, and the base plates are all in the shape of a dovetail and a single-layer mesh bottom. The bonding strength between the bracket and the tooth surface depends to a large extent on the structural form of the bracket base plate. This kind of base plate structure often causes the bracket to fall off the tooth surface during the orthodontic treatment process. In this case, it not only causes great trouble to patients and doctors, but also affects the treatment cycle and effect. Therefore, in order to solve these problems, we propose a bracket with a firm bottom plate to solve the problem.

[0003] The patent document with the publication number CN210673468U in the prior art provides a ceramic bracket. This ceramic bracket is adhered to the tooth surface by adhesively bonding a bracket matrix and a metal groove with resin, and then fixing the wire with a ligature wing in cooperation with a bracket elastic band.

[0004] Although this ceramic bracket has many beneficial effects, there are still the following problems: This ceramic bracket is adhered to the tooth surface by adhesively bonding multiple prominent tooth position marks with resin. Its structure is single, the bonding area is small, and the fixing effect on the bracket is poor, which needs to be improved; secondly, the fixing ligature wing of this ceramic bracket needs to be used in cooperation with a bracket elastic band to fix the wire, and the wire cannot be fixed quickly, and the convenience of the device needs to be improved. Therefore, a bracket with a firm bottom plate is proposed for the above problems. Content of the Utility Model

[0030] Please refer to Figures 1-5 The present invention provides a technical solution:

[0031] A bracket with a firm bottom plate, the bottom plate assembly 1 includes a base bottom plate 110 and a fixed frame 150. A first fixing plate 160 is installed above the base bottom plate 110, and a sliding frame 120 is installed above the base bottom plate 110. The fixed frame 150 is used to fix the fixing rack 240 and connect the mesh layer 210. The sliding frame 120 can cooperate with the movable plate 310 to slide the fixing assembly 3, facilitating the fixing of the wire to the bracket.

[0032] The installation component 2 includes a grid layer 210 above the installation fixing frame 150, an installation fixing frame 240 installed below the grid layer 210, a second fixing groove 250 opened on the side wall of the fixing frame 240, and a groove 260 opened on the side wall of the fixing frame 150. The grid layer 210, the second fixing groove 250, and the groove 260 can increase the contact area with the resin, improve the fixing effect on the bracket, and prevent the bracket from falling off. The resin can fill the second fixing groove 250.

[0033] The fixing component 3 includes a movable plate 310 slidably connected to the side wall of the sliding frame 120. An upper fixing plate 320 is installed above the movable plate 310. An elastic spring piece 340 is installed on the side wall of the upper fixing plate 320. A clamping block 350 is installed on the side wall of the elastic spring piece 340. The sliding frame 120 can cooperate with the sliding groove 130 to slide the movable plate 310. After driving the upper fixing plate 320, the elastic spring piece 340, and the clamping block 350 to slide, the clamping block 350 can be clamped into the first fixing groove 170 to fix the steel wire.

[0034] Specifically, a sliding groove 130 is provided on the side wall of the sliding frame 120, and a limiting block 140 is provided on the inner wall of the sliding frame 120. The sliding groove 130 is used to cooperate with the sliding frame 120 to slidably connect the movable plate 310, so that the fixing component 3 can be slid, facilitating the fixing of the steel wire on the installed bracket. The limiting block 140 can cooperate with the second fixing block 330 in the sliding groove 130 to limit the movable plate 310 on the sliding frame 120, preventing the movable plate 310 from detaching from the sliding frame 120.

[0035] Furthermore, a convex block 230 is installed above the base plate 110, and a first fixing block 220 is provided above the convex block 230. The convex block 230 is used to connect the first fixing block 220 and the base plate 110. The first fixing block 220 can increase the contact area between the bracket and the resin when the bracket is adhered to the tooth surface with resin, preventing the bracket from detaching.

[0036] It should be noted that a second fixing block 330 is installed above the movable plate 310, and an installation hole 360 is opened above the elastic spring piece 340. The second fixing block 330 can cooperate with the limiting block 140 to limit the movable plate 310 on the sliding frame 120. By using the installation hole 360 to cooperate with an installation tool to press the installation hole 360 and push upward, the clamping block 350 can be clamped into the first fixing groove 170. Also, the clamping block 350 can be pulled out of the first fixing groove 170 by using the installation hole 360 to cooperate with an installation tool, facilitating the installation of the steel wire.

[0037] It should be noted that a first fixing groove 170 is provided on the side wall of the first fixing plate 160. There are multiple elastic spring pieces 340 and clamping blocks 350, and there are multiple first fixing grooves 170. The clamping block 350 can be clamped into different first fixing grooves 170 according to the thickness of the steel wire. Multiple elastic spring pieces 340 cooperate with the clamping blocks 350 to fix the steel wire, and the fixing effect is good.

[0038] In addition, the accessory materials and modules involved in the present utility model are all prior arts, which can be fully implemented by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either;

[0039] Working principle: Before using the bracket to correct teeth, first fix the bracket to the tooth surface through the surface of the resin combined with the base plate 110, the grid layer 210, the first fixing block 220, the convex block 230 and the fixing frame 240. The resin fills the second fixing groove 250 and the groove 260, increasing the contact area between the resin and the bracket and improving the fixing property of the bracket. After fixing the bracket to the tooth surface, use the installation tool of the bracket to cooperate with the installation hole 360 to pull out the clamping block 350 from the first fixing groove 170, then install the wire on multiple brackets, and then use the sliding frame 120 to cooperate with the movable plate 310 to slide the second fixing plate 320 and the elastic spring piece 340 to drive the clamping block 350 to slide. Then use the installation tool to cooperate with the installation hole 360 to hold the elastic spring piece 340 and clamp the clamping block 350 into different first fixing grooves 170 according to the thickness of the wire to fix the wire.
