Does implant location influence the risk of peri‐implantitis?

Abstract Peri‐implantitis is characterized by nonreversible and progressive loss of supporting bone and is associated with bleeding and/or suppuration on probing. Peri‐implant disease is considered as the main etiologic factor related to implant failure. Peri‐implant disease has a pathogenesis similar to that of periodontal disease, both being triggered by an inflammatory response to the biofilm accumulation. Although the prevalence of peri‐implantitis has been evaluated by several clinical studies with different follow‐ups, there are currently little data on the impact of implant location and the prevalence of peri‐implantitis. The aim of this review, therefore, was to summarize the evidence concerning the prevalence of peri‐implantitis in relation to implant location and associated risk predictors. Even though most studies evaluating the prevalence of peri‐implantitis in relation to implant location are cross‐sectional or retrospective, they suggest that the occurrence of peri‐implantitis is most prevalent in the anterior regions of the maxilla and mandible. Moreover, it seems that there is a higher prevalence of peri‐implantitis in the maxilla than in the mandible.
