Advanced peri-implantitis may lead to severe peri-implant tissue destruction and, in selected cases, require implant removal. A clinical case report prepared within the PERI-EDU project presents the surgical management of an implant affected by advanced active peri-implantitis, with particular attention to Er:YAG laser-assisted debridement and decontamination of the peri-implant defect.

The case involved an implant with clinical and radiological signs of advanced peri-implantitis, including deep probing values, bleeding on probing and significant peri-implant bone loss. The implant was removed surgically, followed by careful defect decontamination. The clinical protocol included the use of an Er:YAG laser as an adjunctive tool supporting removal of inflamed tissue and surface decontamination in the peri-implant area.

An important educational aspect of the report is the connection between local peri-implant tissue destruction and systemic inflammatory assessment. Selected CBC-derived inflammatory indices, including SII, SIRI and AISI, were calculated and interpreted as potential additional markers reflecting systemic inflammatory activation. While such indices should not be treated as standalone diagnostic tools, they may help broaden clinical thinking about peri-implantitis as a disease influenced by local, host-related and systemic factors.

The case illustrates several key learning points relevant to clinical education:
