Which skeletal condition carries the HIGHEST risk of implant (osseointegration) failure because of dense, poorly vascularized, non-remodeling bone?
Show answer and explanation
Correct answer: C. Osteopetrosis
- A. Osteoporosis lowers density but does not preclude osseointegration.
- B. Osteopenia is milder than osteoporosis and not the worst risk.
- C. Correct. Osteopetrosis produces dense, avascular bone with impaired remodeling and poor healing, the highest osseointegration-failure risk among these.
- D. A history of osteomyelitis is a concern but not the dense-bone mechanism asked here. (Smoking was not an option.)
