Implants · single question

All of the following can contribute to failure of implant osseointegration EXCEPT:

  1. Absence of occlusal loading (no occlusion)
  2. Overheating bone during osteotomy
  3. Micromovement during healing
  4. Bacterial contamination/peri-implantitis
Show answer and explanation

Correct answer: A. Absence of occlusal loading (no occlusion)

  • A. Correct. Lack of occlusal contact does not cause failure; it is excessive load/overload and micromovement that threaten integration.
  • B. Overheating bone (>47°C) causes osteonecrosis and failure.
  • C. Micromotion during early healing leads to fibrous encapsulation and failure.
  • D. Infection/peri-implantitis causes bone loss and failure.
