How long does an implant survive after peri-implantitis treatment? Dr. Mario Roccuzzo offers his insights on treating cases of severe peri-implantitis, with examples of clinical cases of implants in function 10 years after peri-implantitis treatment. His treatment protocol is based on minimally invasive flap opening, cleaning the surface of the implant, using deproteinized bovine bone mineral, and connective tissue graft when adequate soft tissue is not available.
