Correct answer: D — Peri-implantitis associated with local irritant

Inflammation with suppuration, deep pockets, and progressive implant bone loss is peri-implantitis, with residual cement acting as a local risk factor. Peri-implant mucositis lacks progressive supporting bone loss. The pearl is that implant maintenance requires probing, radiographic comparison, and removal of excess cement where accessible.
