How realistic an option are jaw implants?

I'm a 22 year old guy who I think most people probably consider to be fairly good-looking. But I hate my jaw, it's hard to explain but it's just…weak. I know I'd be way more attractive if I had a stronger, more masculine looking jaw and have heard that some plastic surgeons are able to insert jaw implants to achieve the exact effect I'm looking for. Except the whole thing sounds a little sketchy to me, how can they could even do such a thing? So is it possible to get a legitimate jaw implant and are there any other ways I could get my jaw looking stronger?
