Osseointegration

Osseointegration refers to the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant without intervening fibrous tissue (StatPearls, 2023). This process is fundamental to the success of dental implants and orthopedic prostheses, such as hip and knee replacements. The biological sequence begins with blood clot formation and protein adsorption on the implant surface, followed by the recruitment of osteogenic cells and the formation of woven bone, which eventually matures into lamellar bone (PubMed, PMID: 28603311). While osseointegration is a physiological process rather than a single molecular target, it is modulated by various signaling pathways including Wnt/beta-catenin and BMP signaling (NIH, 2021). Drugs like teriparatide or bisphosphonates are often studied for their ability to enhance this process in patients with compromised bone quality. Successful osseointegration ensures the long-term stability and load-bearing capacity of prosthetic devices in the human body. Factors such as implant surface topography and the systemic health of the patient significantly influence the rate and quality of integration (PubMed, PMID: 31503810).

Pharmacological agents typically enhance osseointegration by stimulating osteoblast activity (anabolic) or inhibiting osteoclast-mediated bone resorption (antiresorptive) at the bone-implant interface (PubMed, PMID: 31503810).
