Infected implant - is it possible to clean out the infection and do a bone graft around the implant?

I have an infection that has eaten away the bone around an implant, I am currently on antibiotics and have an appointment to have the implant extracted. The problem is it's a front tooth, I really don't want to have it extracted at all, I am wondering because it is firmly seated in the upper bone. Is it possible to clean out the infection while leaving the implant and doing a bone graft around the implant? and leaving the entire "tooth" intact? what would that entail?
