Ed, my jaw was radiated six ways from Sunday and I have some dandy implants. Getting them involved hyperbaric therapy, but they are firmly planted and chew very well. I would suggest a second or third opinion. If I can have them, I think just about anyone can. The guy who did them is an ENT/DDS and his middle name is Arrogance, but he does good work. He used to be at M.D. Anderson, and I will be seeing him on the 13th if you want me to ask him for a TX referral. Lower implants and an upper denture are not like real teeth, but they are so very close that I will never complain. Let me know if I can help.
