Peri-implant inflammations represent serious diseases after dental implant treatment, which affect both the surrounding hard and soft tissue. Due to prevalence rates up to 56%, peri-implantitis can lead to the loss of the implant without multilateral prevention and therapy concepts. The Medline, Pubmed, Embase, NCBI, and Cochrane databases were searched for studies of patients with non-alcoholic fatty liver disease. Incidence, etiology, and management options were analyzed. Peri-implant inflammations, potentially leading to implant loss at a 56% prevalence rate, require preventive measures like continuous check-ups, addressing risk factors, and choosing appropriate treatments. Conservative methods are effective for early stages, while advanced cases benefit from surgical interventions following the Cumulative Interceptive Supportive Therapy (CIST) protocol, providing essential guidance for practitioners.
