Background technique

It is well known that abnormal growth of the teeth, abnormal growth of the jaws, bad habits such as sucking fingers during infancy, bad eating habits and/or genetics can cause the teeth to not grow in the proper position, resulting in irregularly arranged teeth. The teeth are misaligned or cause the face to protrude. Irregularly arranged teeth, malocclusion or facial protrusions not only image the aesthetics of the teeth and face, but also reduce the uniform chewing of the food as a basic function of the teeth, which is not conducive to food digestion. With the improvement of living standards, people pay more and more attention to teeth. Through the treatment of teeth, correction, whitening, etc., the teeth can be made more neat and beautiful.

In general, orthodontics can be in two stages, with the first stage requiring loose teeth and the second stage requiring realignment of the teeth after rearrangement. Currently, various types of orthodontic appliances are available in the industry to correct teeth, such as a orthodontic appliance with a vibrator that can be used to control the corrective brachial vibrations to force the teeth in the mouth to loosen and rearrange to correct the teeth. However, such orthodontic appliances generally require tailoring of the corrective braces that match the patient's teeth, depending on the exact size and shape of the patient's teeth. With the improvement of people's living standards, the demand for orthodontics is increasing, and this customized orthodontic device is difficult to meet the needs of mass. In addition, not every tooth in the patient's mouth needs to be corrected. For example, some regular healthy teeth do not need to be corrected, and only a part of irregular teeth need to be corrected. If a dental appliance with a vibrator is used, it is not possible to selectively correct the teeth that need to be corrected. In the process of orthodontics, it is possible to vibrate the teeth without correction, which may damage other regular healthy teeth. .

When the vibrator 201 is turned on, the front correcting piece 21 can be driven to vibrate together with the rear correcting piece 22, so that the vibration acts on the irregular teeth to slowly loosen the irregular teeth. In the present embodiment, since the vibration frequency and the strength of the vibrator 201 are based on the slow loosening of the teeth, and the continuous periodic vibration is used to match the pain of the human body to adapt to the sexy, no pain is generated during the loosening of the teeth.

In this embodiment, since the volume of the root portion is generally larger than the volume of the cusp portion, when the irregular tooth is loosened, the root portion is pressed to press the correcting braces 3 to generate greater pressure, and the irregular tooth and the corrective braces 3 are at this time. The pressure between them changes, indicating that the irregular teeth in the patient's mouth are loose. When the irregular teeth are loosened by the action of the vibrator 201, the position correction of the irregular teeth is completed because the correcting cuff 3 applies pressure to the loose irregular teeth and displaces the irregular teeth to a predetermined position.

The frosted layer 202 is made of a high-hardness diamond sanding material, which can be used for grinding and trimming the upper surface of the tooth. When the front correcting piece 21 and the rear correcting piece 22 vibrate, the frosted layer 202 also vibrates together, so that the upper surface of the irregular tooth can be polished and trimmed, thereby making the irregular tooth more beautiful and tidy.
