The present invention relates to a screw for orthodontic anchors that are applied as anchors, i.e. anchors, in orthodontic procedures, and more particularly, a structure capable of preventing damage to the gum mucosa by a traction member connected for movement of an orthodontist. To orthodontic anchor screws.

For modern people, appearance, especially impression, serves as a criterion for judging people during job interviews and admissions, and plays an important role in social life. It is a factor that influences overall. Accordingly, orthodontics for the improvement of teeth, dental dentition, or facial skeleton along with plastic surgery are prevalent.

The orthodontic treatment includes an orthodontic treatment that corrects malformed teeth, that is, an orthodontic treatment that simply prepares a crooked tooth, and an orthodontic treatment that corrects skeletal incongruity of the jaw that may occur during the growth process. It creates healthy oral tissue and aesthetic face.

However, there are cases where the abnormality of the upper and lower teeth meshing or facial skeletal structure is too severe. In this case, orthognathic surgery is applied to correct the abnormality of the facial skeleton itself with surgery to make a functional and aesthetic face. .

In other words, Orthognathic Surgery may be used when the improvement of facial shape and improvement of dental function are incomplete with only the orthodontic treatment that adds orthodontic force to jawbone or dentition. In particular, in the case of growing children, the orthodontic surgery may be avoided by a method such as skeletal improvement through orthodontic treatment by the addition of orthodontic force, but the orthodontic surgery is applied to an adult whose growth is terminated.
