What term refers to the bond between living bone and the surface of an implant fixture?

• A. Osseointegrated
• B. Osteointegration
• C. Fibrointegration
• D. Biocompatibility

Answer: (A)

Osseointegration is the direct structural and functional connection between living bone and the surface of an implant fixture. When an implant is osseointegrated, bone has formed a bond with the implant surface, providing stable, load-bearing fixation. Some texts use a similar spelling, osteointegration, but osseointegration is the standard term. Fibrointegration would involve fibrous tissue at the interface, which does not provide true bonding and compromises stability. Biocompatibility describes how well a material interacts with tissues in general, not the actual bond formed between bone and implant.
