Mesh skin graft applied to the leg. From McQuillan et al., 2002.

Ollier-Thiersch graft a very thin skin graft in which long, broad strips of skin, consisting of the epidermis, rete, and part of the corium, are used.

sieve graft a skin graft from which tiny circular islands of skin are removed so that a larger denuded area can be covered, the sievelike portion being placed over one area, and the individual islands over surrounding or other denuded areas.

skin graft a piece of skin transplanted to replace a lost portion of skin; see also skin grafting.

split-skin graft (split-thickness graft) a skin graft consisting of the epidermis and a portion of dermis.

graft,

n a slip or portion of tissue used for implantation. See also donor site; recipient site.

graft, allo-,

n a graft between genetically dissimilar members of the same species.

graft, allogenic,

n a graft using tissue from the same species (i.e., person to person). See also allograft.

graft, alloplast

n a graft of an inert metal or plastic material.

graft, auto-,

n See graft, autogenous.

graft, autogenous

n a graft taken from one portion of an individual's body and implanted into another portion of the individual's body.

graft, autogenous bone,

n the bone that is removed from one area of a patient's body and transplanted into another area that requires additional bony material. Such bone grafts are advantageous because they contain live active cells that promote bone growth.

graft, bone,

n the transplantation of healthy bone tissue to a defective bone cavity so that the new bone tissue meets the surrounding, unaffected surface and promotes healing and new growth.

graft, bone, allograft,

n a bone graft using tissue obtained from an individual other than, but of the same species as, the host of the bone graft; sources include human cadavers, living relatives, and nonrelatives. Also called
allogeneic graft and
homograft.

graft, bone, autogenous,

n See graft, autogenous.

graft, composite,

n a transplant involving living tissue made of different materials, such as skin and cartilage.

graft donor site,

n the site from which graft material is taken.

graft, filler,

n the filling of defects, such as bone chips used to fill a cyst.

graft, free,

n a graft of tissue completely detached from its original site and blood supply.

graft, full-thickness,

n a skin graft consisting of the full thickness of the skin with none of the subcutaneous tissues.

graft, gingival,

n a graft in which a thin piece of tissue is taken from the palate of the oral cavity, or moved over from adjacent areas, to provide a stable band of soft tissue around a tooth or implant.

graft, hetero-,

n See graft, heterogenous.

graft, heterogenous

n a graft implanted from one species to another.

graft, homo-,

n See graft, homogenous.

graft, homogenous

n a graft taken from a member of a species and implanted into the body of a member of the same species.

graft, iliac,

n a bone graft whose donor site is the crest of the ilium. Various locations of the iliac crest duplicate areas of the mandible and curvatures of the midfacial skeleton.

graft, iso-,

n a graft between individuals with identical or histocompatible antigens.

graft, kiel,

n a denatured calf bone used to fill defects or restore facial contour.

graft, mucosal,

n a split-thickness graft involving the mucosa.

graft, onlay bone,

n a graft in which the grafted bone is applied laterally to the cortical bone of the recipient site, frequently to improve the contours of the chin or the malar eminence of the zygomatic bone.

graft, particulate,

n a surgical tissue implant or graft consisting of various particles, e.g., used in the stimulation of bone growth.

graft, pedicle

n a stem or tube of tissue that remains attached near the donor site to nourish the graft during advancement of a skin graft.

graft, ramus,

n the surgically removed bone taken from the ascending ramus of the mandible for the purpose of transplantation.

graft, split-thickness,

n a graft with varying thickness containing only mucosal elements and no subcutaneous tissue.

graft, swaging,

n a procedure analogous to bone grafting. Also referred to as a
contiguous transplant, which involves a greenstick fracture of bone bordering on an infrabony defect and the displacement of bone to eliminate the osseous defect.

graft, Thiersch's skin

n.pr a split-thickness skin graft containing cutaneous and some subcutaneous tissues, the line of cleavage through the rete peg layer.
