There are bigger issues that MUST be addressed right now that supercede the consideration of implants. There is an infectious process at play here. This HAS to be brought under control. There is a risk of losing all the work that has occurred reconstructivly to this point if it is allowed to prosper. I am appalled that the doctors that you are talking to are not more concerned about this. You need a second opinion from a head and neck surgeon as to what is going on and an appropriate course of action forward from this point. Your husband likely needs to be on some aggressive antibiotic treatment at minimum, and perhaps needs surgical intervention if the infection has involved the implants holding the osseous reconstruction together. An extraction after radiation was a risky venture ,and that there was infection involved at that site and not addressed seems grossly out of order. I do not wish to alarm you with this post, but none of these post 02 treatments feels like it was handled well. While you say that your husband is disinclined to redo things, or have additional surgery to fix what is obviously wrong... he needs to get his head around the fact that something is wrong that needs to be fixed, it is not going away on its own, and it is unlikely that his body is going to bring this under control on its own.
