Bacterial species associated with peri-implant disease - a literature review.

Peri-implantitis is a pathological condition in dental medicine that manifests as an inflammatory process affecting the tissues surrounding dental implants. Peri-implantitis occurs when the soft and hard tissues surrounding these implants become inflamed, leading to progressive destruction of the supporting bone. The etiology of peri-implantitis is multifactorial, involving microbial, host-related, and environmental factors. Microbial involvement in peri-implantitis can be explained either by direct in-situ virulence activation leading to pathogenicity, or by induction of low-grade chronic immune activation, leading to long-term persistence of a pro-inflammatory status. Understanding peri-implantitis is pivotal in maintaining the long-term success of dental implants and improving patient outcomes in implant-supported restorations. Recognizing the etiological factors, including particular bacterial species, genetic predispositions, and environmental influences, is very important for devising effective preventive strategies and targeted interventions.
