osteointegration

osteointegration

The direct structural and functional connection between living bone and the surface of a load-bearing implant; osteointegrated implants have been used to treat edentulism, and for head and neck reconstruction to facilitate retention of auricular mandibular, maxillary, nasal, and orbital implants, and for bone-anchored hearing aids. See Dental implant.

The company has also developed radiopaque fibers to help visualize positioning using X-ray and osteoconductive options that promote osteointegration, "especially with 'all suture' anchors for soft tissue repair and reconstruction," said Cooney.

For example, it allows engineers to simplify processes, such as adding a porous surface layer to implants to ensure better osteointegration while improving how a patient's bone grows into it.
Additive Manufacturing Benefits Orthopedic Restoration: Knee replacements, spinal implants, and other orthopedic devices can be brought to market faster and at lower costs through additive manufacturing
One of strategies to improve the osteointegration of implantable devices is to modify the surface of implant with the materials that are similar to the human hard tissues.
PULSED LASER DEPOSITION OF BIOACTIVE COATING FROM WHITE PORTLAND CEMENT
Several studies have attempted to treat osteonecrosis by transplanting exogenous stem cells (MSCs) either systemically or locally, or biphasic calcium phosphate (BCP) ceramic scaffolds seeded with MSCs on inducing osteointegration and new bone formation.24,25 Osteonecrosis research has focused on the effectiveness of bisphosphonates, growth factors, lipid-lowering agents, and combined drug therapies.

It was concluded that the irradiated surfaces undergo considerable changes in surface properties including wettability, mechanical and electrical properties, as well as exhibited unique bioactivity, forming spherical macro-porous apatite layer which can enhance osteointegration and osteoconduction.
