In other words, it is impossible to treat with the simple tooth movement because the abnormality of the lower teeth and the facial skeletal structure, especially the jaw structure, are too severe. In such cases, Growth Modification. In adults, moderate to severe skeletal anomalies are also used in conjunction with the above-mentioned treatments for orthognathic surgery in which functional and / or aesthetic faces are corrected by correcting abnormalities of the jaw itself.

The orthodontic treatment can be broadly divided into a straight side correction and a lingual correction. The straight side correction is a technique in which a correcting mechanism used for orthodontic correction is attached to the surface of the lips (the outer surface of the teeth) And the lingual correction is a correction method in which the orthodontic appliance is attached to the surface of the tooth (Lingual) (the inner surface of the tooth) of the tooth to perform orthodontic correction.

On the other hand, in the dental orthodontic treatment, the correction for moving the teeth (front teeth) of the anterior portion to the lingual side, for example, the palatal side is referred to as lingual pulling, and in the case of the dental protrusion in which the patient's teeth are abnormally protruded forward, As a result, the lingual traction described above is presented as one of the methods for correcting the entrance and exit. In addition, the anterior teeth are spread to the lingual side even during orthodontic treatment with anterior crowding. For the aforementioned lingual traction, that is, for the rearward movement of the anterior portion, a curved wire of a curved shape conforming to the teeth of the anterior portion is provided inside the oral cavity through a wire supporter (bracket) on the lingual side or the inferior side of the anterior portion.

However, when the above-described orthodontic treatment is carried out in the conventional manner, anterior teeth may be pulled backward, causing problems such as tilting of the teeth and unevenness of vertical positions.

In order to prevent the above-described phenomenon, it is possible to induce stable movement of the anterior portion by connecting the wire wire to the bracket of the posterior portion. However, both ends of the wire wire may damage the oral soft tissue during movement of the anterior portion, When a practitioner wishes to use a dental tool, such as a wire cutter (Distal End Cutter) to cut both ends of an orthodontic wire or wire, the structural characteristics of the oral cavity cause the dental tool The accessibility of the apparatus is deteriorated and the procedure becomes difficult.
