Alternatives to Chin Implants & Sliding Genioplasty

I am interested in augmenting my chin but am wary of the reactions that are possible by having a foreign body placed inside me. I was more interested in a sliding genioplasty for a while as it seemed to have less long term complications compared to a chin implant, but I've found evidence that the titanium screws/plates are a hazard as well. Is there any other method of augmenting the chin, even if slightly, with safer methods such as fat grafting?
