How does osseointegration occur in a dental implant?
Show answer and explanation
Correct answer: B. Direct contact between living bone and implant surface
B) Direct contact between living bone and the implant surface — CORRECT.
Osseointegration, as defined by Brånemark, is the direct structural and functional connection between ordered living bone and the surface of a load-bearing implant — without any intervening fibrous or soft tissue layer.
A) Ankylosis involves fusion of root to bone (pathological in teeth); while analogous, the preferred clinical term for implants is osseointegration — not ankylosis.
C) Indirect contact (fibrous encapsulation) = implant failure. A fibrous tissue interface indicates lack of osseointegration.
D) Vascularization is necessary but not sufficient to describe osseointegration.
