Correct answer: C — Healthy peri-implant tissue

Explanation lettering: B = shown as A · E = shown as B · A = shown as C · C = shown as D · D = shown as E

The correct answer is A: Healthy peri-implant tissue. The 2017 World Workshop consensus and SDCEP guidance define peri-implant health by the absence of bleeding on probing, erythema, swelling, and suppuration. Probing depth alone is not diagnostic—health can exist at any probing depth if these inflammatory signs are absent. The patient meets all criteria for health: no bleeding, no suppuration, no erythema is implied, and only normal initial remodelling on radiographs. Option B (mucositis) requires bleeding on probing as its main diagnostic feature; this patient has none. Option C (peri-implantitis) requires progressive bone loss beyond remodelling in addition to clinical signs of inflammation; neither is present. Options D and E are implausible in this clinical context.
