VIENNA, Austria: According to a large-scale study review by Derks et al.,¹ one in five implant patients develops peri-implantitis, and nearly twice as many suffer from peri-implant mucositis, which can progress to peri-implantitis if left untreated. Peri-implantitis causes irreversible damage that compromises the long-term aesthetics and function of implant restorations—and often results in implant failure. In a recent consensus workshop, the European Federation of Periodontology (EFP) classified peri-implantitis as a growing public health concern due to its high prevalence.²
