The diagnosis "aggressive periodontitis", defined by the International Workshop for a Classification of Periodontal Diseases and Conditions in 1999, refers to the multifactorial, severe, and rapidly progressive form of periodontitis, which primarily - but not exclusively - affects younger patients. Direct and indirect bacterial effects influencing the host immune response play a significant part in the etiology of aggressive periodontitis comparable to chronic periodontitis. In addition to various virulence factors of specific periodontal pathogens, a genetic predisposition influences the outbreak and progression of the disease. After diagnosis, which should be made as early as possible by clinical and microbiological diagnostics, the usual treatment methods include: mechanical debridement as well as the supportive use of antibiotics, in some cases guided tissue regeneration methods. In addition, the dentition has to be reconstructed functionally and esthetically restorations or implants. A long-term success of therapy demands an appropriate periodontal maintenance.
