Like teeth can get periodontal disease, similarly, dental implants can get an infection in the surrounding gums that is called peri-implantits. This is accompanied by a loss of the bone around the implant and over long-term could lead to implant loss.
Peri-implantitis is characterized clinically by bleeding and pus discharge from the gum around the implant and on the x-ray, by loss of bone around the implant.
Since peri-implantits may lead to implant loss and its treatment is not entirely predictable, the best strategy to follow is a preventive one. Careful self-performed cleaning has to be exercised from the patient as soon as the prosthesis is installed. Patient affected by severe periodontal disease might be more prone to get similar problems around the implants. Adherence to the recommended supportive program is therefore strongly advised.
