Several risk factors or risk indicators have been associated with an increased risk of developing peri-implantitis including the history of periodontitis, poor plaque control, lack or irregular maintenance care, and smoking . Interestingly, all these factors are also known risk factor/indicators for periodontitis.
Peri-implant mucositis and peri-implantitis constitute two clinical phenotypes that compromise the health of peri-implant tissues. Evidence supports a close association between the mainly Gram-negative bacteria associated with periodontitis and the microbiome around the implants with clinical signs of peri-implantitis.
Consequently, implementation of adequate infection control and proper periodontal support therapy is fundamental prior to implant therapy.
Because it is challenging to successfully treat peri-implantitis once established, it is of crucial importance to prevent its initiation and progression, which requires knowledge of the pertinent risk factors.
Conclusions: Peri-implant diseases have a complex etiology and pathogenesis which parallels periodontitis. Both have mutual risk indicators including a dysbiosis of the biofilm, poor compliance with maintenance, enhanced inflammatory responses, smoking and diabetes.
