Pirih1 1School of Dentistry, Section of Periodontics, University of California, 2School of Dentistry, Department of Periodontology, Federal University of Pelotas This is a report on an experimental model of ligature-induced peri-implantitis in mice. We describe all surgical steps, from pre- and post-operative management of the animals, extractions, implant placement, and ligature-induced peri-implantitis.
