Peri-implantitis and periodontitis — two different entities?

Peri-implantitis is a disease affecting peri-implant tissues. It is characterised by bleeding/suppuration on probing together with loss of supporting bone. Recent evaluations on the prevalence of the disease indicate that about 20% of implant-carrying patients present with significant peri-implantitis problems. In the presentation results from recent studies on peri-implantitis and periodontitis will be reported and important differences between the two conditions will be described. While subjects with a history of severe periodontitis have higher risk for the disease, the presentation will also bring up the role of implant surface characteristics in relation to peri-implantitis. Thus, results from pre-clinical in vivo studies will be presented and their relevance to clinical outcomes will be discussed.

Learning objectives:

  • Human and preclinical documentation of treatment of peri-implantitis and periodontitis. What are the main differences between the two diseases?
  • Influence of implant design and surfaces on progression of peri-implant disease
  • Influence of implant design and surfaces on treatment of peri-implantitis


Dr Berglundh graduated (LDS) 1978 in Gothenburg and received his certificate as specialist in Periodontics in 1992, the degree of Odont. Dr. (PhD) in 1993, the Docent (Associate Professor) degree in 1994 and the Professor degree in 2002 from the Department of Periodontology, The Sahlgrenska Academy at University of Gothenburg, where he has served since 1981.

Presently, Dr. Berglundh is Professor at the Department of Periodontology and Head of the Periodontal Research Laboratory at University of Gothenburg. He is Associate Editor of Clinical Oral Implants Research and Journal of Clinical Periodontology and the textbook Clinical Periodontology and Implant Dentistry. Dr. Berglundh has produced more than 170 scientific publications within the field of dental implants, periodontology, immunology, genetics, tissue integration and regeneration. Interactions between periodontitis and peri-implantitis represent one of the major fields of research and include translational systems of combinations of molecular biology techniques, experimental models and clinical trials.
