Which of the following does NOT favor implant bone loss (peri-implant bone loss)?

Correct answer: C. Excessive chewing

• A. Proximity to a periodontally compromised tooth (with furcation involvement) can be a risk factor for peri-implant bone loss via bacterial cross-contamination.
• B. Parafunctional habits (e.g., bruxism) generate excessive occlusal forces, a recognized risk factor for peri-implant bone loss.
• C. Correct (the exception). 'Excessive chewing' (normal masticatory function) is not classically recognized as a risk factor for peri-implant bone loss in the way pathological forces (bruxism) are.
• D. Poor oral hygiene is a well-established risk factor for peri-implantitis and bone loss.

Note: 'Excessive chewing' is not a risk factor for peri-implant bone loss in the same way bruxism or furcation proximity is.
