Description

Orthodontic appliance

The present invention relates to a orthodontic appliance that acts as a fixed source for orthodontic or jaw correction, and more particularly, to a orthodontic appliance that can impart orthodontic force in both directions based on a base body fixed to the jawbone.

For modern people, appearance, especially impression, serves as a criterion for judging people during job interviews and admissions, and plays a very important role in social life, taking up a large proportion in interpersonal relationships.

As a result, artificial plastic surgery on the human body is becoming popular in spite of men and women of all ages. Among them, plastic surgery on major organs of the face, for example, eyes, nose, and mouth, has been in the spotlight. On the other hand, teeth and orthodontics generally influence the impression. Recently, orthodontics are performed to even out the teeth.

However, the abnormality of the upper and lower teeth meshing or facial skeletal structure (jawbone skeletal structure) is so severe that orthodontic treatment, that is, orthodontic treatment by movement of the teeth cannot be treated. Orthognathic surgery is being applied to correct the abnormalities to make a functional and aesthetic face.

In other words, the orthodontic surgery may be applied alone or in parallel with the orthodontic treatment when the orthodontic treatment for applying gradual force to even the teeth is incomplete in improving the shape of the face and the improvement of the dental function. In particular, the adult growth of the jaw bones may be difficult to treat malocclusion or skeletal improvement by orthodontics alone. In this case, the orthodontic surgery may be used.

The orthognathic surgery, also called jaw correction surgery or simply jaw surgery, corrects this variation in shape and size when the maxilla (bone) or mandible (bone) is out of normal and has an excess, lack, or asymmetric growth state. Says surgery.

Specific examples of the orthognathic surgery, for example, difficult to chew, bite or swallow food, if there is a problem in pronunciation, chronic pain around the jaw bone, teeth are abnormally worn out a lot, the front teeth do not touch If you can't eat food with your incisors, if you touch only the incisors and the molars don't touch, if you have asymmetry on your face (when your face is crooked), or if your face is damaged by an accident, There are no jaw cases, and it is difficult to close the lips.

The orthognathic surgery is generally a change in the position and shape of the jaw bone through the osteotomy and recombination or resection of the jaw bone, through which a more beautiful facial line than the state before surgery can be formed.

The orthognathic surgery is performed only through surgery to correct the position of one of the maxillary and mandibular surgery, or through double jaw surgery (operation to correct the position by simultaneously cutting the maxillary and mandibular surgery).

After the orthodontic surgery, orthodontic treatment such as orthodontic treatment by indentation of the anterior part, additional orthodontic movement, and prevention of tooth alignment may be involved. Orthodontic treatment is generally performed using metal or ceramic brackets and wires. It is performed using an orthodontic device, and an elastic traction member such as a rubber band or a spring is connected to the orthodontic fixed source so that the orthodontic teeth can move.

The orthodontic fixed source is configured to be connected to the traction member, that is, a correction member for applying orthodontic force after being fixed in the oral cavity, especially the upper or lower jaw.

On the other hand, in the case of orthodontic surgery to correct the jaw by severing the jaw bone, there is a problem that the physical pain and cost burden to the patient, in addition to the orthodontic surgery method to stiffen the jaw bone to correct the bones by gradually applying the corrective force to the bone Improved orthodontic techniques can be applied in the field of orthodontics. Particularly, in the case of growing children, the orthodontic surgery can be avoided by a method such as skeletal improvement through orthodontic treatment of jaw bone.

However, when the correctional force is applied to the jaw bone to achieve skeletal improvement as described above, the correction force is applied to the jaw bone by fixing a plurality of fixed circles in the maxillary and / or mandible and connecting the anchorages to add correction power. The process of embedding the fixed circle in the oral cavity is complicated and the burden and foreign body feeling felt by the patient is increased. In the case of a headset-type orthodontic device worn on the outside of the face, there is a problem such as inconvenient life and visual discomfort.

Accordingly, the present inventors, it is fixed to the jaw so as to apply the corrective force to the jaw for gradual improvement of the skeleton can be applied as a fixed source of jaw correction orthodontics, can also be applied as a fixed source for orthodontic, through one installation Dental orthodontic appliances have been developed that can serve as two or more anchors.
