Bone grafts are placed typically right after extractions are completed, but sometimes we can place them years after lost teeth to widen a ridge. The bone graft we use is an allograft or from a human organ donor. It is basically dried up bone pieces that can be packed into an area where we want bone to be. The bone graft material goes through a very detailed tedious sterilization process to ensure the best result. The allograft has an excellent safety record and is well documented in clinical trials. If patients take care of their site well, we see great results of bone growth. Reasons to get a bone graft is to widen a ridge or fill in an odd shaped bone defect so there is enough room to place an implant.
