Description

Technical Field

[0001] The utility model relates to the technical field of teeth correction devices, in particular to a teeth orthodontic correction bracket. Background Art

[0002] In orthodontic oral treatment, most people choose to wear light-force braces to correct their teeth. The braces are mainly composed of archwires and brackets. The archwires and brackets move relative to each other, thereby generating corrective force to move the teeth.

[0003] For example, a tooth orthodontic bracket disclosed in Chinese patent application number CN201721301342.2 has the following specific contents: when in use, the amount of the screw in each cavity is adjusted according to the preset direction of the arch wire, so that the upper and lower guide plates are respectively set to an inclination consistent with the preset direction of the arch wire, thereby obtaining an arch wire groove corresponding to the traction force. Then, after the base plate is glued to the tooth surface at a certain angle and position, the arch wire is set in the arch wire groove formed between the two guide plates, and then the insert on the inner side of the C-shaped spring piece is aligned with the slot, so that the entire C-shaped spring piece is inserted downward. Since the C-shaped spring piece has a certain elastic force, it is pulled outward to open to a certain extent when inserted, until the hook at the bottom passes over the arc surface and is inserted into the slot, so that the entire C-shaped spring piece wraps around the bracket body, the first protrusion and the second protrusion. It has the following technical problems:

[0004] After wearing common orthodontic brackets for a period of time, the teeth will gradually retract inward, making the teeth more aligned and gradually developing in a better direction. In this case, the archwire on the bracket will become looser and looser. In order to avoid excessive friction between the loose archwire and the bracket surface, which may cause heavy metals to precipitate into the human body, the archwire is adjusted after a period of time after wearing the bracket. This requires multiple visits to the hospital for correction during the entire correction cycle, which is rather cumbersome. Utility Model Content

[0033] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0034] See also Figure 1-Figure 6 The utility model provides an orthodontic bracket. When the arch wire 10 becomes loose, the elastic plate 234 pushes the lifting plate 220 at all times, so that the contact plate 210 always pushes the arch wire 10, and the lifting plate 220 is inserted between adjacent limit blocks 213 to lock the lifting plate 220, thereby completing the locking of the contact plate 210, and finally making the arch wire 10 continue to be taut, avoiding the loose arch wire 10 from continuously rubbing against the surface of the correction bracket 001, and also avoiding the heavy metals precipitated due to friction from causing harm to the human body, and can prolong the use time of the arch wire 10, thereby reducing the number of times the patient goes to the hospital.

[0035] The device includes a correction bracket 001 for cooperating with the tie wire 20 to limit the position of the arch wire 10. The correction bracket 001 includes a mounting back plate 100 fixedly mounted on the tooth surface. The front end of the mounting back plate 100 is mounted with a first connection block 110 and a second connection tray 120 for limiting the position of the tie wire 20. The first connection block 110 and the second connection tray 120 have the same size and structure, and the first connection block 110 and the second connection tray 120 are arranged in mirror symmetry. The first connection block 110 is located at the upper end of the mounting back plate 100, and two first connection blocks 110 are provided. The second connection tray 120 is located at the lower end of the mounting back plate 100, and two second connection trays 120 are provided.

[0036] The first connection drag block 110 has a first limiting groove 111 at the upper end thereof for limiting the binding wire 20, and the second connection tray 120 has a second limiting groove 121 at the lower end thereof for cooperating with the first limiting groove 111 to limit the binding wire 20. When the arch wire 10 is passed through the front end of the fixed block 200 and is located between the first connection drag block 110 and the second connection tray 120, the binding wire 20 is passed through the first limiting groove 111 and the second limiting groove 121, so that the arch wire 10 is located at the rear end of the binding wire 20, and the first limiting groove 111 is tightened so that the first limiting groove 111 limits the arch wire 10. The first limiting rod 130 for limiting the contact plate 210 is installed at the upper end of the second connection tray 120, and the two ends of the first limiting rod 130 are respectively fixedly connected to the upper ends of the two second connection trays 120. The first limiting rod 130 is provided to facilitate the rotation of the fixed block 200.

[0037] A fixing block 200 is installed at the middle of the front end of the mounting back plate 100. The fixing block 200 includes a contact plate 210 for pushing the loose arch wire 10. The contact plate 210 includes a first plate body 211. The lower end of the first plate body 211 is provided with a first limiting hole 212 for cooperating with the first limiting rod 130 to limit the first plate body 211. The first limiting rod 130 is movably installed in the hole cavity of the first limiting hole 212. The first plate body 211 is fixedly installed with a plurality of holes for cooperating with the lifting plate 220. The lifting plate 220 locks the first plate body 211 with a limit block 213, and a slot a is formed between adjacent limit blocks 213, and one end of the limit block 213 facing the first limit hole 212 is set as an arc edge to facilitate the second plate body 221 to slide to the next slot a, and the other end of the limit block 213 is set as a right-angle edge, so that when the limit block 213 is inserted into the slot a, the second plate body 221 is locked, so that the lifting plate 220 cannot be reset.

[0038] A lifting plate 220 for pushing one end of the contact plate 210 is installed at one end of the contact plate 210, and the lifting plate 220 includes a second plate body 221, and a pressing rod 224 for pushing the second plate body 221 is installed at one end of the second plate body 221 facing the limit block 213. When the arch wire 10 is installed, the contact plate 210 is kept away from the lifting plate 220, and the pressing rod 224 is pushed so that the pressing rod 224 drives the second plate body 221 to move. The first plate 21 moves into the groove cavity of the third limiting groove 232, and pushes the first plate 211, so that the first plate 211 blocks the third limiting groove 232. When the arch wire 10 is loose, the elastic plate 234 pushes the second plate 221, and the second plate 221 pushes the first plate 211. Finally, the first plate 211 pushes the arch wire 10, so that the arch wire 10 in the middle of the mounting back plate 100 is raised, thereby completing the fastening of the arch wire 10. The second plate 221 is provided with a second limiting hole 222 at the other end, and the second limiting rod 233 rotates in the hole cavity of the second limiting hole 222. A plurality of reinforcing ribs 223 for increasing the strength of the second plate 221 are fixedly installed on one side of the second plate 221.

The middle part of the groove cavity of the third limiting groove 232 is provided with an elastic plate 234 for pushing the second plate body 221. The elastic plate 234 is a V-shaped elastic plate. The elastic plate 234 always pushes the second plate body 221, so that the first plate body 211 applies a thrust to the arch wire 10, thereby increasing the tightness of the arch wire 10, and the arch wire 10 is not easy to rub against the surface of the correction bracket 001.
