osseointegration
Pronunciation: ah-see-oh-in-teh-GRAY-shun
Direct structural and functional connection between living bone and implanted material surface.
Full Definition
Osseointegration is a biological process whereby living bone tissue forms a direct structural and functional connection with the surface of an implanted material, typically titanium or titanium alloys. Originally described in dental implantology, this concept has expanded to include craniofacial implants, auricular prostheses, and bone-anchored hearing aids used in plastic and reconstructive surgery. Successful osseointegration requires biocompatible materials, appropriate surface characteristics, adequate bone quality and quantity, and careful surgical technique. The process typically takes several months and results in a stable, load-bearing interface between the implant and bone.
Usage
Usage note: Specific to bone-implant interface; distinguish from general tissue integration.
