Hello - There are certain advantages to each.The genioplasty and chin implant both allow you to create a more balanced profile but don't change your bite.A more elaborate jaw surgery could allow your teeth to allign differently but requires many months of recovery and orthodonture.It's well worth going in for an inperson consult with someone who does alot of facial skeletal surgery.Best of luck

A chin implant is placed when patient's have a receding, weak chin profile. Chin implants are composed of Silastic, are inserted through segmental approach under local anesthesia as an outpatient surgical procedure. A sliding genioplasty is performed under general anesthesia in a hospital setting by oral surgeon with an overnight stay at the hospital.

Given your young age, the degree of horizontal chin shortness and that you are a female, I would lean towards a sliding genioplasty. This is a procedure that, once done and the desired aesthetics are achieved, will never pose any long-term problems and can more effectively bring your chin forward (and vertically shorter if desired) without any risk of making it wider which is an important aesthetic consideration for a female. While a chin implant is definitely simpler with a quicker recovery, the choice of implant style and positioning on the bone must be carefully done to avoid making the chin wider and longer.

Your x-ray and photos are very helpful. You have a Class II dental bite.  This means your lower jaw did not grow as much as it should have. The best option is to align the teeth again by orthodontics and bring the lower jaw forward.  This would take about 16 months. Second option is sliding genioplasty. You could probably bring your chin forward 5-6mm without harming the labiomental fold.

based upon your images and xray, you have to be cautious with the chin surgery using either method. In your image, notice the 'shadow; under your lower lip which is due to the lower incisors being quite tilted forward and pushing the lip forward. This creates a deeper fold. The same thing is visualized on the xray where you see the tilted lower incisors/forward tilt. If you advance the chin, the surgeon must consider the depth of this fold which will increase notably; so you will need to deal with this to achieve a natural look without looking 'chinny'.
