Thank you
It is very difficult to give you right answer without in person evaluation. It appears that both sliding genioplasty and chin implant augmentation would produce significant improvement. Hope this helps.
A genioplasty is performed by an oral surgeon under general anesthesia in a hospital setting with an overnight stay, and is more invasive. It is usually performed when the teeth are significantly out of alignment. Consider placement of a chin implant to augment your chin forward which can be done under local anesthesia as an outpatient procedure
