If it is a simple tooth deformity, it can be improved by corrective surgery, but once the contour chin is involved, it is not just a tooth problem. It is likely that the outline or chin needs to be improved.
As you said, short chin is probably one of the common convex correction operations in orthodontics, which is characterized by prominent face and mouth, with short chin or even no chin on the side.
In this case, it is necessary to carry out convex correction surgery, improve the convex formed by protruding teeth, move the chin osteotomy forward to make up for the short chin, and restore the face to normal through two-way correction.
If it is really because of tooth deformity and short chin caused by protruding mouth, surgery is not an easy task. Many stomatological hospitals can't improve very well. It is recommended to consult a regular hospital that can do maxillofacial plastic surgery. After all, safety is more important!
