Purported symptoms of metallosis generally include pain around the site of the implant, pseudotumors (a mass of inflamed cells that resembles a tumor but is actually collected fluids), and a noticeable rash that indicates necrosis. [1] The damaged and inflamed tissue can also contribute to loosening the implant or medical device.
The plateau-root form design has a woven bone formation. In the 0-3 month bone healing phase, osseointegration occurs by intramembranous ossification. Intramembranous ossification provides greater stabilisation and a more significant role in peri-implant bone healing around plateau-root form implants than screw-root form designed implants. [9]
Bone grafts are used in hopes that the defective bone will be healed or will regrow with little to no graft rejection. [19] Besides the main use of bone grafting – dental implants – this procedure is used to fuse joints to prevent movement, repair broken bones that have bone loss, and repair broken bone that has not yet healed.

Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year.

This is the loss of bone caused by the body's reaction to polyethylene wear debris, fine bits of plastic that wear off the cup liner over time. An inflammatory process causes bone resorption that may lead to subsequent loosening of the hip implants and even fractures in the bone around the implants. Ceramic bearing surfaces may eliminate the ...
As with many operations, allotransplantation risks some side effects. A limiting factor in tissue allotransplantation for reconstructive surgery deals with the side effects of immunosuppression (metabolic disorders, malignancies, opportunistic infections) which is a predominant issue. The risk of transmitting infection is high.
An implant is a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. For example, an implant may be a rod, used to strengthen weak bones. Medical implants are human-made devices, in contrast to a transplant, which is a transplanted biomedical ...
Bone grafting – used in dental implants, as well as other instances. The bone may be autologous, typically harvested from the iliac crest of the pelvis, or banked bone/allograft. [2] Vascular grafting – the use of transplanted or prosthetic blood vessels in surgical procedures.
