Can a second cadaver bone graft take, if the first failed?

You need to look closely at thecircumstances that caused the bone graft to fail. Where was the graft placed? A bone graft that is surrounded by walls of bone on all four sides should be successful because it hasthe greatest source of bone cells available to turn the grafted bone into your own bone. A graft that does not have walls to contain it has the poorest chances of turning over into bone that you can use. Putting pressure or micromovement of the graft during the time it is healing can cause the graft to fail. Without looking at your particular case and obtaining the necessary information, it is impossible to predict what will happen in a second graft, but if everything is done the same way, it may fail again unles you determined the reason it failed. Ask the dentist for a reason why it failed, and if you are not satisfied with the answer, get a second opinion from an experienced implant dentist. Good luck!Dr. Carlos Boudet
