Description

Technical Field [0001] The present invention relates to an orthodontic appliance for lingual pulling,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an orthodontic appliance and a method of manufacturing the same, and more particularly, to an orthodontic appliance for lingual pulling used for pulling a dentition to a lingual side and a method of manufacturing the same.

For modern people, the appearance, especially the impression, acts as a criterion for judging people in interviews such as employment or entrance, and also plays a very important role in social life, such as occupying a large portion in interpersonal relationships. Especially, As a whole. As a result, dental orthodontics for the improvement of teeth, teeth, or facial skeleton are being performed along with plastic surgery.

The dental orthodontics is a concept that includes corrective dentition, for example, orthodontic orthodontics that simply aligns crooked teeth. It can correct various skeletal mismatches that can occur during the growth process, , Contributing to healthy oral tissues, and further enhancing the facial lines, thereby providing a beautiful facial image.

The dental orthodontic treatment can be classified into orthodontic treatment which improves dentition such as malocclusion through progressive movement of the teeth, and orthognathic surgery which gives a skeletal improvement by performing surgical operation on the jaw.

In other words, it is impossible to treat with the orthodontic treatment, ie, orthodontic treatment, because the abnormality to the engagement of the lower teeth or the abnormality to the facial skeletal structure is too severe. In such a case, Orthodontic surgery is applied in parallel with the orthodontic treatment to create an aesthetic and aesthetic face.

That is, the orthognathic surgery can be used only when the orthodontic treatment improves the facial shape and the improvement of the dental function is incomplete. In particular, in the case of growing children, the orthognathic surgery can be avoided by a method such as skeletal improvement through orthodontic treatment. However, in the case of an adult whose growth has been completed, the operation is difficult only with the orthodontic operation. Surgery may be performed in parallel with the orthodontic treatment.

The orthodontic treatment can be roughly divided into a straight side correction and a lingual correction.
