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.
Peri-implant mucositis becomes peri-implantitis when bone resorption is identified around the implant on a radiograph as well as all the signs associated with peri-implant mucositis is seen. Often, pus may also exude from the tissues surrounding the implant.
At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
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.

Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants. White blood cells of the donor's immune system which remain within the donated tissue (the graft) recognize the recipient (the host) as foreign (non-self). The ...
Graft-versus-leukemia (GvL) is a specific type of GvT effect. As the name of this effect indicates, GvL is a reaction against leukemic cells of the host. GvL requires genetic disparity because the effect is dependent on the alloimmunity principle. GvL is a part of the reaction of the graft against the host.
Peri-implant mucositis is defined as an inflammatory lesion of the peri-implant mucosa in the absence of continuing marginal bone loss. [1]The American Academy of Periodontology defines peri‐implant mucositis as a disease in which inflammation of the soft tissues surrounding a dental implant is present without additional bone loss after the initial bone remodeling that may occur during ...
Zygoma implants take the anchorage from the zygoma/zygomatic bone (cheek bone). The zygomatic bone is denser in quality and more cortical in nature than posterior maxillary bone. [ 5 ] Because of the sturdy anchorage achievable in the dense bone of the zygomatic region, and the wide stress distribution achieved on these tilted implants, a ...
