Peri-implantitis is a pathological condition occurring in tissues around dental implants. It is caused by microorganisms and characterized by inflammation in the peri-implant connective tissue and loss of supporting bone. Peri-implantitis sites exhibit clinical signs of inflammation, bleeding on probing and/or suppuration and increased probing depths in addition to radiographic bone loss.
The presentation will report on the new classification of peri-implant diseases with case definitions in day-to-day clinical practice and in epidemiological studies. Results from recent studies on peri-implantitis and periodontitis using human samples will be presented and important differences between the two conditions will be described. The understanding of disease onset and progression for peri-implantitis will be addressed from the comparison between periodontitis and peri-implantitis. The presentation will also address the role of implant surface characteristics in relation to peri-implantitis. The presentation will include surgical therapy of peri-implantitis and treatment outcomes reported in clinical trials and experimental studies will be presented. Factors influencing resolution of peri-implantitis following surgical therapy will also be discussed. Thus, the effect of adjunctive systemic antibiotics in surgical therapy and the influence of implant surface characteristics on the outcome of treatment of peri-implantitis will be addressed. Data from pre-clinical in vivo experiments and randomized controlled clinical trials will be presented.
