Biocompatibility. Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
The prosthetic implant used in hip replacement consists of three parts: the acetabular cup, the femoral component, and the articular interface. Options exist for different people and indications. The evidence for a number of newer devices is not very good, including: ceramic-on-ceramic bearings, modular femoral necks, and uncemented monoblock cups.
Titanium and its alloys are safe from attraction and torque forces produced by the magnetic field, although there may be some risks associated with Lenz effect forces acting on titanium implants in sensitive areas within the subject, such as stapes implants in the inner ear.
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.
For osseointegrated dental implants, metallic, ceramic, and polymeric materials have been used, in particular titanium. 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 histologic terms.
Implant (medicine) Orthopedic implants to repair fractures to the radius and ulna. Note the visible break in the ulna. (right forearm) A coronary stent — in this case a drug-eluting stent — is another common item implanted in humans. An implant is a medical device manufactured to replace a missing biological structure, support a damaged ...
Biocompatibility: Ability to be in contact with a living system without producing an adverse effect. [1] Biocompatibility is related to the behavior of biomaterials in various contexts. The term refers to the ability of a material to perform with an appropriate host response in a specific situation. [2] The ambiguity of the term reflects the ...
A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biological process called osseointegration, in ...
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 ...
Root analogue ceramic dental implant in comparison with titanium screw type implant. As technology has improved, so has implant success rate. Conventional titanium dental implants typically have success rates of 90-95% for 10 years follow up periods, but this is based on questionable definitions of success. [1]
