How do you treat peri-implantitis?

Correct answer: C. Mechanical debridement + antiseptic rinses ± antibiotics ± surgical intervention

• A. Antibiotics alone without mechanical debridement are insufficient for peri-implantitis.
• B. Extraction is a last resort for failing implants — most cases are managed conservatively first.
• C. Correct. Peri-implantitis treatment follows a step-by-step approach: (1) Non-surgical phase: mechanical debridement of the implant surface, local antiseptics (chlorhexidine), antibiotics if indicated; (2) Surgical phase (if non-surgical fails): open flap debridement ± bone regeneration. The goal is to eliminate infection and stop bone loss.
• D. Peri-implantitis does not resolve without treatment — it is a progressive condition.
