Case in brief
A patient developed pain and peri-implant mucosal changes after delivery of a screw-retained implant-supported fixed prosthesis. One site progressed to ulceration and sloughing, with tissue appearing clinically non-viable. Management involved relieving prosthetic pressure, debriding affected tissue where indicated, antiseptic rinses, and providing a passive-fitting redesigned restoration. The mucosa healed, symptoms resolved, and function was restored; the patient reported no discomfort during follow-up. The authors proposed the provisional descriptive term peri-implant mucosal pressure injury (PIMPI), while noting that the absence of histopathological, microbiological, pressure, and perfusion assessments limits conclusions about causation.
What made this case unusual
The report proposes PIMPI as a descriptive label for a pressure-associated peri-implant mucosal injury pattern, including ulceration and sloughing after prosthesis delivery. The proposed relationship to prosthetic compression remains uncertain, and the presentation’s distinction from peri-implant mucositis, peri-implantitis, and other prosthetic-biomechanical complications is unresolved.
Diagnostic / clinical pearl
Painful peri-implant mucosal breakdown after prosthesis delivery may warrant assessment of soft-tissue compression and prosthetic fit. Improvement after pressure relief and redesign is consistent with a possible contribution, but does not establish causation.
Why it matters
The provisional terminology may help describe and investigate this presentation, but further clinical and biologic studies are needed to characterize it and clarify its relationship to established peri-implant conditions.
