I want Orthognathic surgery, also how much does it usually cost?

I used to think that I needed a chin implant until a doctor said that my chin is fine, but my lower jaw just needs extended a little more. I do not know how the teeth are supposed to line up but my bottom teeth touch the roof of my mouth just behind my top teeth, and my lower jaw also feels like it is too far back when I relax my face.
