A patient with diabetes mellitus and HIV (viral load 50,000), generalized 7-10 mm probing depths, and a fixed bridge spanning teeth #7-#11 has a guarded periodontal prognosis. What is the most appropriate prosthetic treatment plan?

With advanced periodontal breakdown and a failing fixed prosthesis, removing hopeless teeth, controlling infection, and providing an implant-supported overdenture offers the most stable, hygienic long-term result once the patient is medically optimized.Other options: Ignoring the infection, relying on a temporary acrylic RPD as definitive care, or retaining a failing bridge does not provide a durable solution.Key exam takeaway: Advanced periodontal collapse with a failing FPD: stabilize health, extract hopeless teeth, then consider implant-supported overdentures.
