Correct answer: A — Plaque control with supportive implant care

**A is correct.** Effective plaque control and regular supportive peri-implant care are central to preventing peri-implant mucositis and peri-implantitis, thereby protecting long-term implant survival. SDCEP advises effective self-performed oral hygiene, regular monitoring of peri-implant tissues, and implant-specific maintenance; it notes that maintenance care is associated with increased implant survival rates. **B** and **C** may be relevant technical choices in particular systems, but neither replaces control of biofilm and ongoing maintenance. **D** is not a biologically meaningful determinant of outcome. **E** is a design feature that may affect primary stability in selected clinical settings, but it is not the dominant long-term prognostic factor once osseointegration has been achieved. The key discriminator is recognition that long-term success is principally protected through prevention and early detection of peri-implant disease.
