This kind of graft is known as a vital bone graft. [citation needed] An autograft may also be performed without a solid bony structure, for example, using bone reamed from the anterior superior iliac spine. In this case, there is an osteoinductive and osteogenic action, however, there is no osteoconductive action, as there is no solid bony ...
The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and ...
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
The term free describes how the graft is completely removed from the donor site rather than remaining attached via a pedicle. 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.
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 ...
Allograft bone is a logical alternative to autograft. However, it must be rigorously processed and terminally sterilized prior to implantation to remove the risk of disease transmission or an immunological response. This processing removes the osteogenic and osteoinductive properties of the graft, leaving only an osteoconductive scaffold. These ...
When the human body is unable to regenerate the lost bone tissue, surgeons come in and replace the missing bone using autografts, allografts, and synthetic grafts (artificial bone). When comparing artificial bone to autograft and allograft, it is less invasive and more biocompatible since it avoids the risk of unknown viral infections. [3]
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
