Osseointegration
Osseointegration (from Latin ''osseus'' " bony" and ''integrare'' "to make whole") is the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant ("load-bearing" as defined by Albrektsson et al. in 1981). A more recent definition (by Schroeder et al.) defines osseointegration as "functional ankylosis (bone adherence)", where new bone is laid down directly on the implant surface and the implant exhibits mechanical stability (i.e., resistance to destabilization by mechanical agitation or shear forces). Osseointegration has enhanced the science of medical bone and joint replacement techniques as well as dental implants and improving prosthetics for amputees. Definitions Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which oste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Munjed Al Muderis
Professor Munjed Al Muderis (born 1972) is an Australian Adjunct Clinical Professor in orthopaedic surgery, author and human rights activist. He has done pioneering work on prosthetics, especially on titanium devices. Al Muderis was born in Iraq and became a surgeon under the regime of Saddam Hussein. He was a medical student in Basra at the start of the Gulf War in August 1990. As a junior surgeon, he fled from Iraq following an incident in which he refused to mutilate the ears of army deserters. He traveled through Indonesia and Malaysia and reached Australia where he was kept in at an immigration detention centre near Derby, Western Australia. He was released after 10 months and carried on his career in medicine, eventually specialising in osseointegration surgery. Al Muderis wrote the book ''Walking Free'' on his experiences in Iraq, in the Australian immigration detention system, and on his career in Australia. Early life Munjed Al Muderis was born under the regime of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Per-Ingvar Brånemark
Per-Ingvar Brånemark (May 3, 1929 – December 20, 2014) was a Swedish physician and research professor, acknowledged as the "father of modern dental implantology". The ''Brånemark Osseointegration Center'' (BOC), named after its founder, was founded in 1989 in Gothenburg, Sweden. Biography After studying at Lund University in Sweden, Brånemark became professor of Anatomy at Gothenburg University in 1969. Brånemark has been awarded many prizes for his work, including the coveted Swedish Society of Medicine's Soederberg Prize in 1992—often referred to as the 'mini- Nobel'—and the Swedish Engineering Academy's equally prestigious medal for technical innovation. Brånemark has also been honored with the Harvard School of Dental Medicine Medal for his work on dental implants in the United States and holds more than 30 honorary positions throughout Europe and North America, including the Honorary Fellowship of the Royal Society of Medicine in the UK. In 2003, he received an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osseoincorporation
Osseoincorporation refers to the healing potential of bone onto an implant surface and into an implant structure. Three-dimensional, porous implantable materials used in the orthopedic and dental implant industries offer the potential for ingrowth as well as ongrowth or osseoincorporation. Comparison to osseointegration Conventional textured or coated implant surfaces are designed to achieve bone-to-implant contact, which is called ''ongrowth''. Per-Ingvar Brånemark defined this ongrowth phenomenon, osseointegration, as "the direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant." In the case of dental implants, they osseointegrate. Porous implantable materials are designed for bone to grow not only onto the material but also into its pores, and in some cases interconnecting within the material’s structure, in a process called ''osseoincorporation''. Complications In some cases, the patient has periodontal defe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosthesis
In medicine, a prosthesis (plural: prostheses; from grc, πρόσθεσις, prósthesis, addition, application, attachment), or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth (congenital disorder). Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools. Types A person's prosthesis should be designed and assembled according to the person's appearance and functional needs. For instance, a person may need a transra ...

Implant (medicine)
An implant is a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. Medical implants are man-made devices, in contrast to a Organ transplant, transplant, which is a transplanted biomedical tissue. The surface of implants that contact the body might be made of a Biomaterial, biomedical material such as titanium, silicone, or apatite depending on what is the most functional. In some cases implants contain electronics, e.g. artificial pacemaker and cochlear implants. Some implants are Biological activity, bioactive, such as Subcutaneous tissue, subcutaneous drug delivery devices in the form of implantable pills or drug-eluting stents. Applications Implants can roughly be categorized into groups by application: Sensory and neurological Perception, Sensory and Neurotechnology#Implant technologies, neurological implants are used for disorders affecting the major senses and the br ...

Osteosynthesis
Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century. An internal fixator may be made of stainless steel, titanium alloy, or cobalt-chrome alloy. or plastics. Types of internal fixators include: * Plate and screws * Kirschner wires * Intramedullary nails Open reduction Open Reduction Internal Fixation (ORIF) involves the implementation of implants to guide the healing process of a bone, as well as the open reduction, or setting, of the bone. ''Open reduction'' refers to open surgery to set bones, as is necessary for some fractures. ''Internal fixation'' refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Implant
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 biologic process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown. Success or failure of implants depends on the health of the person receiving the treatment, drugs which affect the chances of osseointegration, and the health of the tissues in the mouth. The amount of stress that will be put on the impla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
