I had an Iliac Crest bone graft and two implants placed in my upper jaw. My insurance (Federal Blue Cross) covered both procedures. I have had to make several calls to my insurance company to explain my circumstances, and they have always covered my expenses following my calls. It as been three months since the teeth (crowns) were installed and I couldn't be happier with them. I did initially lose some of the graft so the rear tooth is slightly cantalievered. (no supporting bone under it). I will be going back to the prosthodontist in February and will inquire as to what brand, and size of implants I had installed.
