You appear to be a good candidate for chin augmentation and there are some options available. The most common approach is with a chin implant. Most commonly, these are either silicone or a more porous material. There are pro's and con's with each and your surgeon should discuss those with you. I personally place a screw in all implants to prevent any migration or shifting. This screw is not visible nor palpable. There is the option of making the incision underneath the chin, or going thru the inside of the mouth. Again, there are pro's and con's of each approach that you should be aware of, and in my opinion, going underneath the chin is usually a better option.
There are definitely options other than a chin implant available as well. If your occlusion, or "bite" is normal, then it is possible to move the bottom portion of the chin bone out to give you the look you desire. If your bite is off. then sometimes it is best to move the lower jaw bone out to correct your bite as well as the chin. All of these options should be discussed with your plastic surgeon. Good luck!
