Only autografts are considered permanent. The rest, either because of their composition (degradable by the host) or because of their origin (rejected by the host's immune response), only provide temporary coverage during a few weeks.
What skin grafts are permanent?
Autograft is skin taken from the person burned, which is used to cover wounds permanently. Because the skin is a major organ in the body, an autograft is essentially an organ transplant. Autograft is surgically removed using a dermatome (a tool with a sharp razor blade).
What are the three classifications of skin grafts?

What are the 2 types of skin grafts?
Skin grafts are divided into 2 major categories: full-thickness skin grafts (FTSGs) and split-thickness skin grafts (STSGs). STSGs may be subdivided into thin (0.008- to 0.012-mm), medium (0.012- to 0.018-mm), and thick (0.018- to 0.030-mm) grafts.
What is the best type of skin graft?
Doctors often use full-thickness grafts for small wounds on highly visible parts of the body, such as the face. Unlike split-thickness grafts, full-thickness grafts blend in with the skin around them and tend to have a better cosmetic outcome.

What are the 4 types of skin grafts?
- Autograft or autologous graft: skin obtained from the patient's own donor site.
- Allograft or heterologous graft: skin obtained from another person.
- Xenograft or heterograft: skin from other species, such as pigs.
- Synthetic skin substitutes: manufactured products that work as skin equivalents.
What is the difference between allograft autograft and xenograft?
One of the most common treatments for receding gums is gum grafting, which uses your tissue (autograft), tissue from a donor (allograft), or tissue from an animal (xenograft). In general, there are a few distinct differences between these types of tissue grafts. As a board-certified periodontist, Dr.

What is composite graft?
The term “composite graft” describes the non-microvascular reattachment of the amputated part of soft tissue, usually skin and fat. Excellent results were first demonstrated by Douglas in 1959 [3].
Which type of graft is used the most?
Allograft is the most commonly used bone graft material.
What is autograft and allograft?
A patient's own tissue - an autograft - can often be used for a surgical reconstruction procedure. Allograft tissue, taken from another person, takes longer to incorporate into the recpient's body .
When are full-thickness skin grafts used?
A full-thickness skin graft is used when all layers of the skin are needed to close a wound or to cover small areas. It is used when matching the skin graft's color to the normal skin is important. It may also be done when contractures (tightening and shortening) of the skin graft should be avoided.
What is synthetic skin graft?
They are made of both layers of the skin (dermal and epidermal), ideally mimicking natural tissue. Artificial dermo-epidermal grafts are often prepared by culture of keratinocytes on the surface of the dermal layer with or without fibroblasts incorporated.
When do you need a full-thickness skin graft?
Full-thickness skin grafts are ideal for visible areas of the face that are inaccessible by local flaps or for when local flaps are contraindicated. They retain more of the characteristics of normal skin, including color, texture, and thickness, when compared with split-thickness grafts.

Is AlloDerm a skin substitute?
AlloDerm is used as a dermal substitute in deep partial- and full-thickness burn wounds, facilitating subsequent autologous split-thickness skin graft take. Successful simultaneous grafting on AlloDerm has, however, also been described.
Which is better allograft or autograft?
Which is better? Both of these are often successful options for a graft delivery procedure. While autografts have a higher success rate, allografts result in a quicker recovery time. Depending on the injury, your doctor will be able to make the right call for the type of graft to use.
What is the difference between allograft and homograft?
allograft, also called allogeneic transplant, homograft, in medical procedures, the transfer of tissue between genetically nonidentical members of the same species, although of a compatible blood type.
What is Alloplastic graft?
Alloplastic grafting material is synthetically derived or made from natural materials. The major advantages of alloplastic bone grafts include zero risk of disease transmission and low antigenicity. Alloplastic grafting materials include hydroxyapatite, dicalcium phosphates, and bioactive ceramics.
What is a halo graft?
The “halo” graft is a useful and versatile technique. Partial-thickness grafts are harvested circumferentially from the annulus area around the defect. The mathematical calculation allows for tailoring this technique to defects of various sizes.
How long does a synthetic skin graft take to heal?
The donor area of partial thickness skin grafts usually takes about 2 weeks to heal. For full thickness skin grafts, the donor area only takes about 5 to 10 days to heal, because it's usually quite small and closed with stitches.
What is a full thickness skin graft?
Full-thickness skin grafts (FTSGs) consist of complete epidermis and dermis, whereas partial-thickness skin grafts (PTSG) include the entire epidermis and only partial dermis. One should try to match, as closely as possible, the skin at the recipient site.
