Peri- Implantitis- diagnosis, prevalence and pathogenesis
Peri-implantitis is a disease affecting peri-implant tissues. It is characterized by bleeding/suppuration on probing together with loss of supporting bone. Recent evaluations on the prevalence of the disease indicate that about 15% of implant-carrying patients present with significant peri-implantitis problems. The assessment of the prevalence of the disease, however, depends on case definitions. Subjects with a history of severe periodontitis have higher risk for the disease.
Results from recent studies on peri-implantitis and periodontitis using experimental protocols and 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. Results from pre-clinical in vivo studies will be presented and their clinical relevance will be discussed.
Soft tissue around dental implants
The tissues surrounding dental implants include peri-implant mucosa and peri-implant bone. The integration of hard and soft tissues with the implant device is the result of a wound healing process extending over several weeks. The established peri-implant mucosa presents with an oral epithelium, which is continuous with a junctional epithelium. The interface between the transmucosal portion of the implant and the peri-implant mucosa is comprised by junctional epithelium and connective tissue, the dimensions of which are similar to that of teeth.
The presentation will provide new information on the morphogenesis of the peri-implant mucosa based on human material. The new terminology of the biological width concept will be discussed. The importance of the differences in fiber-mechanical attachment between peri-implant and periodontal tissues on host response to biofilm formation will also be illustrated. The continuum from healthy mucosa to peri-implant mucositis and to peri-implantitis will be addressed.
