Description

Simple tooth correction device using elastic chain {ORTHODONTIC DEVICE}

The present invention relates to a simple tooth correction device using an elastic chain. In more detail, when the movement of the tooth is stopped due to a decrease in elasticity of the retaining device due to the movement of the tooth after completion of the orthodontic treatment, it is immediately reflected and continuously moving the tooth in a desired direction to achieve easy orthodontic treatment. It is about.

In general, a tooth is an important factor that can create a personal appearance due to the appearance image formed from color and shape, and correct alignment of teeth affects not only the tooth itself, but also the skeletal structure of the face. It is known to be an important factor in the formation of.

In particular, the case where the teeth are not evenly formed is called malocclusion. In the case of malocclusion, it is not possible to chew food well and functionally as well as to the effect on the external image, and may adversely affect pronunciation.

In addition, if the malocclusion is neglected, the likelihood of the occurrence of tooth decay or gum disease increases, and other parts of the body have a long-term effect, which may cause or worsen other diseases. Therefore, in the case of malocclusion, it is desirable to maintain the correct dentition state by moving the teeth to the correct position and posture through orthodontics.

In fact, many people gain confidence in their appearance through orthodontic treatment, and in addition, orthodontic treatment can sometimes heal other illnesses that they believe are unrelated to teeth. For this reason, among dental treatments, orthodontic surgery has a long history, and the method and technique have also been remarkably developed. Here, orthodontic refers to a functional or aesthetic treatment that moves a tooth to a desired position in the alveolar bone by applying an appropriate force to the tooth.

In orthodontics, a dental brace is used to gradually move the teeth to fix the position of the teeth. Conventional conventional dental braces include a bracket for orthodontic and an elastic orthodontic wire. If the malocclusion is divided by the difference between the sum of the lengths of the eccentric width of each tooth and the length of the arches for the arrangement of the teeth, the length of the arches in which the teeth are arranged is small and the length of the eccentric width of the entire teeth is large. Will form malocclusions arranged in overlapping form. Conversely, if the length of the arch is greater than the sum of the root myocardial widths of the teeth, the length of the arch is retained even if the teeth are arranged, so that the teeth form a malocclusion that is arranged so that the gaps between the teeth are visible. To this end, in the orthodontic appliance, the bracket is firmly attached to the tooth face of the tooth to be corrected, and the orthodontic wire is mounted in the attached bracket. The orthodontic device has been proposed in Korean Patent Registration No. 10-1512779.

However, in the case of the prior literature, the wire for orthodontics must be constantly replaced and re-installed, and the rubber band connecting the teeth may be detached, so it must be continuously checked and installed, and the orthodontic device should be installed in response to the orthodontic status. In the process of continuously imparting mobility to the teeth by replacement, it is possible to maximize the pain and hassle of the patient, and thus has a problem that it is a major cause of avoiding orthodontics.

To this end, the protruding portion 301 is formed to protrude from one surface of the fixing portion 240 toward the rear, and is formed to correspond to the shape and size of the intaglio groove 243. As the protruding portion 301 is inserted into the intaglio groove 243, the frictional force for rotation can be increased within the fixing portion 240, thereby making it easier to rotate. A plurality of terminal parts for supplying electric power to the induction part 245, which is built in the fixing part 240 and is described above, is provided on one surface of the protruding part 301 facing the fixing part 240, and the inside of the intaglio groove 243 is Another terminal portion corresponding to the plurality of terminal portions one to one is provided. Through this, power can be supplied to the induction part 245 only when the protrusion 301 is accurately inserted into the intaglio groove 243, and thus the first magnetic body 244 can be moved.

The insertion hole 302 is configured to receive the first magnetic body 244 approaching toward the rotating part 300 by the magnetic force between the first magnetic body 244 and the second magnetic body 303. To this end, the insertion hole 302 is formed to correspond to the shape, size, and number of the first magnetic body 244 and is located on one surface of the rotating part 300.

The second magnetic body 303 induces the first magnetic body 244 to be inserted into the insertion hole 302 through a magnetic force with the first magnetic body 244. To this end, the second magnetic body 303 is located inside the insertion hole 302 and is internally provided and provided with a metal material. Here, in order to prevent the second magnetic body 303 from escaping to the outside through the insertion hole 302 by magnetic force with the first magnetic body 244, a separate blocking portion may be formed inside the insertion hole 302. . In addition, the second magnetic body 303 may be provided with an electromagnet that generates magnetism when energized.

Hereinafter, the fastening between the fixing part 240 and the rotating part 300 will be described with reference to FIG. 13.

13A is a case in which electric power is not supplied to the induction part 245, which means that the first magnetic body 244 is not electromagnetically induced. In detail, since the protruding portion 301 is not inserted into the intaglio groove 243, electric power is not supplied to the induction portion 245, so that the first magnetic body 244 remains attached to the fixing portion 240.

On the other hand, Figure 13b is a case where the first magnetic body 244 is inserted into the insertion hole 302, it means a case where power is supplied to the induction portion 245. In detail, as the terminal portion formed on the protruding portion 301 comes into contact with another terminal portion formed inside the intaglio groove 243, the induction portion 245 electrically connected to the other terminal portion receives power and is provided in a coil form. The first magnetic body 244 located in the inner direction of the induction part 245 is moved by being supplied with a magnetic force using electromagnetic induction and inserted into the insertion hole 302. Through this, the fixing part 240 and the rotating part 300 can be fastened to each other and supported by the first magnetic body 244, thereby inducing a more robust and precise rotation. Therefore, the fixing part 240 can be rotated more easily. In addition, the fixing part 240 is rotated by being engaged with the rotating part 300 only when the protrusion 301 is inserted into the intaglio groove 243 and power is supplied to the induction part 245. Therefore, the fixing part 240 can be selectively rotated to maximize safety.
