Is it possible to have all on four implants and underbite jaw correction surgery at the same time?

While it may be POSSIBLE to do jaw advancement surgery at the same time as the "all on four" or "all on X" treatment, it is generally not advised. Both procedures are complex and taxing on the body, with their own set of potential complications. With so many things to manage, it may be difficult to handle simultaneously. It is also possible that "all on X" is all that is really needed, and the jaw advancement can be avoided. I would suggest talking to surgeons that are experienced in each modality and after talking to a few, decide the correct approach.

If you are undergoing All on 4 implant procedure on both jaws, the under bite issue will be taken care during the surgery and also while fabricating the prosthesis. You will not have an under bite issue if the procedures are performed by experienced hands.

Thank you very much for your question, in fact many patients are corrected with the surgery of all on Four, depending on the degree of bite you have.
