Use of implants has increased dramatically in the past 10 yrs Due To

• A. Biointegration
• B. Osteointegration
• C. Osseointegration
• D. Fibrointegration

Answer: (B)

The main idea here is that modern implants achieve their stability through direct bonding with bone. This direct bone-implant connection allows forces to be transmitted into the surrounding bone without a intervening fibrous layer, giving predictable, long-term fixation. That specific process is known as osteointegration (often written as osseointegration as well). The reason implant use has risen so much is that this bone-to-implant integration provides reliable retention and load-bearing capacity, enabling successful prosthetic rehabilitation.

Fibrointegration would mean a fibrous tissue layer sits between implant and bone, which weakens fixation and leads to loosening. Biointegration is a broader term and not as specific to the bone-implant interface. Spelling variants aside, the concept the question targets is the direct bone-implant bond that underpins implant success.
