Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto- meaning "self" in Greek [1]). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant.
The term autogenous, from the Greek root auto-("self"), describes how the individual who receives the graft is the same individual who provides the donor tissue. [ 3 ] The connective tissue is generally taken from the hard palate , although it may be taken from other sites as well, such as the maxillary tuberosity area.
Graft (surgery) Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another creature, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact is called a flap.
Autologous stem-cell transplantation (also called autogenous, autogenic, or autogenic stem-cell transplantation and abbreviated auto-SCT) is the autologous transplantation of stem cells [1][2][3][4] —that is, transplantation in which stem cells (undifferentiated cells from which other cell types develop) are removed from a person, stored, and ...
Guided bone regeneration (GBR) and guided tissue regeneration (GTR) are dental surgical procedures that use barrier membranes to direct the growth of new bone and gingival tissue at sites with insufficient volumes or dimensions of bone or gingiva for proper function, esthetics or prosthetic restoration. Guided bone regeneration typically refers ...
Anterior cruciate ligament reconstruction (ACL reconstruction) is a surgical tissue graft replacement of the anterior cruciate ligament, located in the knee, to restore its function after an injury. [1] The torn ligament can either be removed from the knee (most common), or preserved (where the graft is passed inside the preserved ruptured ...
Graft-versus-host disease (GvHD) is an inflammatory disease that is unique to allogeneic transplantation. It is an attack by the "new" bone marrow's immune cells against the recipient's tissues. This can occur even if the donor and recipient are HLA-identical because the immune system can still recognize other differences between their tissues.
