osseointegration
Pronunciation: OSS-ee-oh-in-teh-GRAY-shun
The direct structural and functional connection between living bone and the surface of a load-bearing implant.
Full Definition
Osseointegration refers to the direct structural and functional connection that forms between living bone tissue and the surface of a load-bearing implant, typically made of titanium or titanium alloys. In craniofacial surgery, this process is crucial for the long-term success of dental implants, bone-anchored hearing aids (BAHA), and craniofacial prosthetics. The process involves the direct apposition of bone to the implant surface without intervening soft tissue, creating a stable mechanical connection. Successful osseointegration requires appropriate implant design, biocompatible materials, proper surgical technique, and adequate healing time without excessive loading.
Usage
Usage note: Not to be confused with simple bone healing or callus formation; refers specifically to direct bone-implant contact.
In Context
- "Successful osseointegration of the dental implants was confirmed radiographically at six months." — Follow-up examination note
- "The BAHA device showed excellent osseointegration with no signs of loosening." — Audiological assessment
