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, orthodontics and jaw control the impression as a whole, in recent years the orthodontic surgery to even the teeth is popular.

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.

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.
