My 2 front top teeth were damaged when I was 13. Last October, at age 50, those teeth were extracted and Bioplant bone graft (synthetic graft) was put in, in anticipation of replacing those teeth with dental implants. The graft has never bonded to my bone, and the specialist now wants to replace the graft with something called Bio-Oss. I believe Bio-Oss is a natural bone graft? I'm wondering if I should go ahead with Bio-Oss or maybe it would be less traumatic for me at this point to simply get a bridge? If so, should I leave in the graft in that didn't "take"? This processs is turning out to be more complicated and expensive that I expected. thank you for any advice.
