What are biomaterials?
Biomaterials are materials used in close or direct contact with the body to expand or replace defective materials. Biomaterials must be compatible with the body to refuse them. In some cases, however, biomaterials, such as organ transplantation, cause rejection that can be solved by rejection medicines.
But even once live materials may not live. They may also have a synthetic origin. For example, bends and pacemakers are considered biomaterials. Gore-Tex® Shunts are an excellent example of biomaterials used to circumvent clogged arteries or provide new paths for circulatory system. They tend to have the advantage of the remaining sound and not the disintegration. Since they do not live, such shorts may be placed in children and require replacement.
Some biomaterials are organic in nature. These include materials such as collagen or fat, often used in the application of plastic surgery. Other biomaterials may include arteriesOr blood vessels taken either from corpses or pigs, which means pig or beef, which means cow, sources. If a person has a main heart valve, one often chooses between a homograph, taken from a corpse source or allograph taken from a source of pig or cow. Another option is an artificial valve, such as Gore-Tex® selection.
Many surgeons prefer biomaterials that are organic than those that are inorganic. However, none of these biomaterials will grow with the body. Homography and alograms also have a slightly lower level of blood clotting than artificial valves and can therefore be preferred by surgeons or patients.
Other biomaterials include certain metals that could be used in bone or joint reconstruction. For example, metal ball sockets can be used in their knees or hips and tend to offer a great fants for those who require joint replacement.
Some biomaterials really live. This is especially in organ transplants. The organs are expected to grow and develop with the body and are better substitutes than inanimate sources. In some cases, an inanimate source such as artificial heart or left ventricular assistance device (LVAD) is used while people are waiting for heart transplantation. These artificial substitutes tend to work for a long time, even if they can give someone the next days or even the few months they need while waiting to receive a transplant.
Other common biomaterials are used in plastic surgery applications. Calf, breast, face, chin and buttocks are considered biomaterials. Occasionally plastic surgeons harvest fat or skin from the body of patients that are used in another part of the body. Skin charts are often used to cover scarring and are most useful in covering large surfaces of burnt, which tends to not regenerate new skin tissue.
one of the most interesting skin biomThe Attrojes recently used was the first facial transplant, performed by surgeons in France. A woman who received transplantation received a partial facial transplant, including new lips and a new nose in 2005. So far her body has not refused this transplant. This first successful transplant can prove to be particularly useful for those whose faces have gone through a serious and irreparable trauma.
