Description

Technical Field

[0001] The utility model relates to the field of tooth correction, in particular to a tooth correction device with a push spring limiting unit. Background Art

[0002] At present, fixed oral appliances are a device for treating tooth deformities, commonly known as braces. They are fixed on the teeth and generate force through their elastic components to change the deformed and misaligned teeth and their periodontal supporting tissues, thereby correcting the malocclusion. Fixed oral appliances generally consist of brackets and archwires. Several brackets are bonded to the retaining teeth with adhesives, and the archwires connect the brackets. The brackets support the correction archwires, and the archwires transmit the restoring force to the teeth being corrected through the brackets.

[0003] In the prior art, the patent document with application number: CN201921953748.8 discloses a multifunctional oral fixed orthodontic appliance with resin balls, including an archwire and a plurality of brackets attached to the outer surface of the teeth by adhesives, buccal tubes are attached to the outer surfaces of the teeth at the ends to be corrected on both sides, and the archwire is fixed by a ligature to connect the brackets and the buccal tubes; the end of the archwire passes through the end buccal tube, and resin balls are arranged on the end tube opening of the buccal tube, the end of the push spring and the two sides of the bracket, which can solve the shortcomings of the existing oral fixed orthodontic appliance, such as the difficulty in bending the archwire end, the looseness, the puncture of the oral mucosa by the archwire end, the need for frequent replacement of the push spring and the easy movement of the archwire left and right.

[0004] During the use of oral fixed orthodontic appliances, the push spring is prone to twist and bulge outward, causing damage to the oral mucosa. In response to the above problems, doctors usually recommend that patients use mucosal protective wax to protect the oral mucosa. However, the mucosal protective wax needs to be removed and discarded when eating and replaced after meals. In addition, the protective wax will soften to varying degrees as the temperature rises, and may even fall off, causing patients to swallow it by mistake, which is extremely inconvenient to use. Another method is to shorten the length of the push spring to avoid excessive twisting of the compressed push spring, but this method has a poor correction effect and increases the number of patient visits. Therefore, it is necessary for us to improve such a structure to overcome the above defects. Utility Model Content

[0005] The utility model aims to provide a tooth correction device with a push spring limiting unit, which is used to solve the problems that the push spring of the existing oral fixed orthodontic appliance is twisted and protrudes toward the lip and cheek due to compression, resulting in poor tooth correction effect, and the push spring itself is easy to damage the oral mucosa.
