Dentistry · Caries, pulp and periodontal disease: peri-implantitis

Sample item

Two years after an implant was placed, a patient has bleeding and pus on probing around it, deepened pockets and saucer-shaped crestal bone loss on a radiograph. The implant is firm. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Peri-implantitis

Peri-implantitis is plaque-related inflammation of the peri-implant tissues with progressive loss of supporting bone, while the implant often stays firm until late. Peri-implant mucositis is the reversible soft-tissue stage without bone loss.

Option by option

  • A. Peri-implant mucositis

    Mucositis is confined to the soft tissues and shows no radiographic bone loss.

  • B. Failed osseointegration

    Failed osseointegration usually shows mobility from fibrous encapsulation soon after placement.

  • C. Implant fracture

    A fractured implant gives sudden mobility or loss of the prosthesis, not saucer-shaped bone loss.

  • D. Peri-implantitis (correct)

    Correct. Inflammation with suppuration and progressive bone loss around a firm implant is peri-implantitis.
