The polymers grafted on the metal surface are brushed, increasing the contact area for cell integration. The cells at the implant interface are highly sensitive to foreign objects. When implants are installed into the body, the cells initiate an inflammatory response which could lead to encapsulation, impairing the functioning of the implanted ...
Metal implants containing a combination of biocompatible metals or used in conjunction with other biomaterials are often considered the standard for many implant types. Passivation is a process that removes corrosive implant elements from the implant-body interface and creates an oxide layer on the surface of the implant.
A transdermal implant (or percutaneous implant), also known as a microdermal implant or surface anchor, is an implant incorporating a flat plate that sits beneath the skin with an externally visible portion incorporating a bead, spike or other item that appears to float on the surface of the skin. Due to the fact that the skin is held open by ...
If you have to get an implant in the future, you may not have to worry quite so much about your body rejecting that life-enhancing technology. Colorado State University scientists have developed a ...
The surface of implants that contact the body might be made of a biomedical material such as titanium, silicone, or apatite depending on what is the most functional. [1] In 2018, for example, American Elements developed a nickel alloy powder for 3D printing robust, long-lasting, and biocompatible medical implants. [ 2 ]
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]

In the literature, one quite often stumbles upon the adjective form, ‘biocompatible’. However, according to Williams’ definition, this does not make any sense because biocompatibility is contextual, i.e. much more than just the material itself will determine the clinical outcome of the medical device of which the biomaterial is a part.
