  3. Osseointegration - Wikipedia

    en.wikipedia.org/wiki/Osseointegration

    For osseointegrated dental implants, metallic, ceramic, and polymeric materials have been used, [2] in particular titanium. [20] To be termed osseointegration the connection between the bone and the implant need not be 100%, and the essence of osseointegration derives more from the stability of the fixation than the degree of contact in ...

  4. Bioceramic - Wikipedia

    en.wikipedia.org/wiki/Bioceramic

    A titanium hip prosthesis, with a ceramic head and polyethylene acetabular cup. Ceramics are now commonly used in the medical fields as dental and bone implants. [8] [9] Surgical cermets are used regularly. Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response.

  5. Joint replacement - Wikipedia

    en.wikipedia.org/wiki/Joint_replacement

    Some ceramic materials commonly used in joint replacement are alumina (Al 2 O 3), zirconia (ZrO 2), silica (SiO 2), hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2), titanium nitride (TiN), silicon nitride (Si 3 N 4). A combination of titanium and titanium carbide is a very hard ceramic material often used in components of arthroplasties due to the ...

    Medical implants are human-made devices, in contrast to a transplant, which is a transplanted biomedical tissue. 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 ...

  7. Mechanical properties of biomaterials - Wikipedia

    en.wikipedia.org/wiki/Mechanical_properties_of...

    Fracture strength. The strength of a material is defined as the maximum stress that can be endured before fracture occurs. Strength of biomaterials (bioceramics) is an important mechanical property because they are brittle. In brittle materials like bioceramics, cracks easily propagate when the material is subject to tensile loading, unlike ...
