It follows that the num- berofperiimplantitiscases,aninfectionoftheperi- implant tissue, increases. Thus, periimplant inflam- mations will become more and more important for dentists in the future. Theprerequisiteforthedevelopmentofproducts for the prevention and therapy of periimplant dis- easeisofcourseasoundknowledgeofitsaetiology, pathogenesis and epidemiology. The majority of early clinical studies used to judge the quality of treatment results by survival rates, with the im- plants remaining physically in the oral cavity. In the beginning, authors saw mechanical incidences as the reason for implant loss rather than biological causes. Today, the health status of periimplant tis- sues has become a focal point for implant survival. Although implant treatment is perceived to be gen- erally successful, periimplant infections occur fre- quently. These are called periimplant mucositis or periimplantitis. Much like periodontal diseases, periimplant diseases are of an infectious origin and can ultimately lead to the loss of the bone support- ing the implant. In periimplant mucositis, the inflammation is by definition restricted to the periimplant mucosa, while periimplantitis also includes the periimplant bone. For positive long-term results of implants as well as for the prevention and treatment of oral in- fections, these diseases must be monitored. The available epidemiological data suggest that one in five patients will develop periimplantitis soonerorlater,andthat,ingeneral,periimplantmu- cositis often occurs in implant patients. Currently, only limited data about the treatment of periim- plant diseases are available. Most of the procedures are oriented towards periodontitis therapy. The most important therapy aim is infection control. This can include the adjustment of dentures, if their form impairs an adequate oral hygiene or the pro- fessional cleansing of the implant surface from biofilm and calcifications.
