Tom, it is my understanding that once the blood supply to the bone has been diminished by radiation, it will be forever more vulnerable. Temporary revascularization can be achieved by a series of hyperbaric oxygen treatments, without which any traumatic occurrences may not heal normally due to lack of blood supply.

I had hyperbaric treatments prior to the placement of lower titanium implants. If I elect to have upper ones placed at this later date, I will have to return to the hyperbaric chamber.

Probably not what you wanted to hear and I am sorry for that.
