Can jaw implants be done from a patient’s own bone?

I'm not sure if you are referring to angle of jaw implants or the chin. A genioplasty procedure uses your own natural chin to be re-positioned in a more aesthetic position. For the angle of the mandible, custom designed implants based on your natural appearance using a CT scan generally provides the best results. There are numerous problems with attempting to use your own bone to enhance the angle of the jaw (resorption, asymmetry, donor site morbidity, fixation). 

Doing jaw augmention using your own bone as an implant isn't typically done due to issues with bone resorption along with the concern for contour irregularities and donor site scars.There are ways to augment the chin by sliding the chin bone forward (sliding genioplasty), though.You can learn more about chin augmentation at my web reference link below.

It is possible to use patient own bone from hip or scull by means of bone graft to augment jaws. This is major procedure that require additional donor site and scar(s), fixation with screws and has less predictable result due to partial bone resorption. This is by all means significantly more complex and expensive procedure in comparison to predictable jaw implants. In person consultation with a board certified [plastic surgeon with expertise in craniofacial surgery and/or facial implants is recommended. Good luck.

Yes, one can use their own bone for a chin augmentation. The reason this is not done normally is that there would be another scar on one's body. The survival rate how long this implant is not predictable. A sliding genioplasty can be done where one's own chin can be moved forward but this would not be considered an implant. This is why most implants are made of silastic material. Best,Michael Kulick MD

Besides the harvest issues, the amount of metal fixation needed to hold them in place and that the shape outcome would not be smooth, onlay bone grafts are associated with significant resorption. For bone grafts to stay and maintain volume they have to be functionally loaded. Adding more bone that is what is naturally there as an only graft has no functional purpose. Thus much of it would be resorbed within one year after tiger surgery 

Look up a surgery called a genioplasty. Essentially the bone is separated and slid down meaning that your augmentation is with your own bone. I'm not sure there is a great utility to it as its not like a silicone implant feels unnatural over time. If done correctly both techniques are equivalent. Hope that helps!

Although, it is possible to sculpt a bone graft and use it as an implant to enhance the jaw, this is not usually done.  The jaw can be enhanced with simpler, more reliable methods which can include cutting the jaw bone and sliding it forward, the use of silastic implants, or through the use of injectable fillers.  Seek out aboard certified plastic surgeon who can discuss the option or options which may be in your best interest.   Best wishes, Dr.Lepore.
