Self-locking tooth alignment device using magnetic closure

The present invention relates to an orthodontic device, and more particularly to a self-locking orthodontic device utilizing magnetic closure.

With the improvement of the quality of life, modern people have higher and higher requirements for appearance. Among them, in order to improve the appearance of teeth and maintain oral health, it is common to use dentition correction to improve the uniformity of teeth.

The conventional orthodontic appliance uses an iron wire or a rubber band to fix the correction arch line in the correction arch line groove. However, the above iron wire or rubber band is likely to cause food residue, which may cause plaque generation. On the other hand, The wire or rubber band may generate friction during the correction process, thus causing the tooth to move at a slower rate, which in turn affects the corrective treatment. Recently, a self-locking orthodontic appliance has been commonly used, which uses a clip or a fastening element on a correction bracket to replace an iron wire or a rubber band, and the correction arch line is fixed to the correction by means of clamping or fastening. The bow line slot is used to improve the above disadvantages.

However, orthodontic treatments are typically longer and it is often necessary to open the orthosis to move the correction archwire during treatment, thereby adjusting the direction of correction. For the use of traditional self-locking orthodontic appliances, While the clip or snap-on switch on the bracket is to be corrected, the operator must apply force to the clip or snap-on component to complete the opening or closing action, which may cause pressure on the operator during operation. And time consumption; in addition, frequent opening and closing may also cause the wear of the clipping or fastening components, which may result in looseness or inability to firmly fix the correction archwire.
