Which of the following is NOT a cause of implant osseointegration failure?
Show answer and explanation
Correct answer: B. Absence of occlusal contact
Absence of occlusal contact does NOT cause implant failure. Functional loading actually promotes bone remodeling. Failure is caused by excessive load, infection, smoking, and inadequate bone.
- A. ❌ Excessive occlusal loading IS a cause of failure through overload bone resorption.
- B. ✅ CORRECT – Absence of occlusal contact does not cause failure; EXCESSIVE load is the issue.
- C. ❌ Smoking significantly impairs healing and increases failure rates.
- D. ❌ Infection/peri-implantitis IS a major cause of failure.
