Osseointegration
open-in-new
<p>Osseointegration (from Latin <i>osseus</i> "<a href="/facts/Bone/kwJaR6IQ">bony</a>" and <i>integrare</i> "to make whole") is the direct structural and functional connection between living <a href="/facts/Bone/kwJaR6IQ">bone</a> and the surface of a load-bearing <a href="/facts/Implant_(medicine)/3PKvy4I2">artificial implant</a> ("load-bearing" as defined by <a href="/facts/Tomas_Albrektsson/71a0V4wm">Albrektsson</a> et al. in 1981). A more recent definition (by Schroeder et al.) defines osseointegration as "functional <a href="/facts/Ankylosis/YKky8W8w">ankylosis</a> (bone adherence)", where new bone is laid down directly on the implant surface and the implant exhibits <a href="/facts/Mechanical_properties_of_biomaterials/MgUULPlo">mechanical stability</a> (i.e., resistance to destabilization by mechanical agitation or <a href="/facts/Shear_force/hVKPYRar">shear forces</a>). Osseointegration has enhanced the science of <a href="/facts/Medicine/2fnp90Je">medical</a> bone and <a href="/facts/Replacement_joint/y7cApCCh">joint replacement</a> techniques as well as <a href="/facts/Dental_implant/8eTEItJg">dental implants</a> and improving <a href="/facts/Prosthesis/odTuXtC0">prosthetics</a> for <a href="/facts/Amputee/Y8w0maCD">amputees</a>. </p>
