Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic instruments, in particular to an orthodontic bracket with adjustable angles. Background Art

[0002] Orthodontic treatment is a highly specialized branch of dentistry, which mainly corrects teeth, jaws, and facial deformities. It gradually restores the patient's normal bite function by fixing orthodontic appliances inside the mouth. Orthodontic brackets are an important part of orthodontic appliances and are mainly bonded to the anterior teeth, canines, and premolars. During orthodontic treatment, the orthodontic brackets are positioned and directly bonded to the surface of each tooth by locating the center of the clinical crown or by keeping a distance from the incisor edge. When the placement of the orthodontic brackets is completed, the archwire is inserted and firmly connected to each bracket through an elastic tie. The archwire applies various types of correction forces to the teeth through the orthodontic brackets. Orthodontic brackets are precision-processed equipment.

[0003] The main function of the archwire is to fix the archwire on the tooth surface so that the archwire can play a better role and transmit the correction force to control the three-dimensional movement of the teeth. The restoring force provided by the archwire to restore its initial arch shape becomes the correction force to move the teeth to the proper alignment, forcing the teeth to move to the correct position and achieve the purpose of orthodontic correction.

[0004] Most traditional orthodontic brackets need to be fixed in place with elastic ties during installation. The tying process is cumbersome, and the elasticity of the elastic ties can easily affect the firmness of the ties during use, causing the position of the orthodontic bracket to be easily displaced over time. In addition, most traditional orthodontic brackets cannot be adjusted in angle, and when correcting severely deformed teeth, it is impossible to adjust the angle of the severely deformed position of the teeth. Summary of the invention

[0022] In this embodiment: when the orthodontic bracket and the archwire are installed, the base 1 is first pasted to the tooth to be corrected, and then the archwire is clamped into the archwire clamping slot 2, and then the installation clamping plate 6 is rotated to drive the clamp arc plate 7 to clamp onto the archwire, so that the retraction plate 11 slidably connected below the installation clamping plate 6 is clamped under the wing plate 8, and then the retraction plate 11 is pushed to make the upper direction of the retraction plate 11 slide into the retraction cavity 10, when the positioning rod 12 fixedly connected to the retraction plate 11 is clamped to the inner side of the wing plate 8, and then the positioning rod 12 and the wing plate 8 are fixedly connected together with a nut, the position of the orthodontic bracket can be adjusted by slightly sliding the base 1 on the archwire, and then the clamp arc plate 7 is fixed to the archwire through the nut hole opened in the middle of the front side of the clamp arc plate 7 with a nut, and the orthodontic bracket is fixed for a second time, which is convenient for quickly installing and fixing the orthodontic bracket on the archwire.

[0023] Please refer to Figure 1 and Figure 4 A threaded column 15 is slidably connected to the rear side of the connecting member 5, and a guide arc plate 16 is fixedly connected to the left and right ends of the front top of the second push plate 14. A first push plate 13 is provided in the middle of the rear side of the base 1, and a positioning support member 17 is meshed and connected to the upper and lower ends of the rear side of the adjusting gear rod 9. The bottom end of the second push plate 14 is rotatably connected to the first push plate 13, and a storage groove is provided on the outer side of the second push plate 14, and an arc guide rail is provided on the outer side of the guide arc plate 16.

[0024] In this embodiment: when adjusting the angle, when the base 1 is fixed to the tooth to be corrected through the archwire, the rotating connector 5 drives the threaded column 15 to rotate according to the angle formed by the upper and lower ends of the tooth, and the rotating threaded column 15 will slide in the direction of the second push plate 14, thereby pushing the second push plate 14 to rotate a certain angle in the direction of the tooth under the action of the bottom end shaft. When the second push plate 14 rotates, the guide arc plate 16 will rotate a certain angle to one side along the arc guide rail. At this time, the thrusts generated by the second push plate 14 and the first push plate 13 are different, which is convenient for correcting the protruding position on the tooth;

[0025] When the base 1 is pasted onto the teeth, the gear rod 9 is rotated and adjusted according to the size of the teeth, thereby driving a group of positioning supports 17 meshingly connected at the upper and lower ends of the gear rod 9 to slide toward one end relative to each other, thereby adjusting the distance between the group of positioning supports 17 so that the size between the back sides of the group of positioning supports 17 matches the size of the teeth.
