What is the definition of a biomaterial
|

|
|
|
List the two genreal type sof implants, and give examples of each.
|
transient implantas are those which are intendend to remain in contact withthe body for a temrporary period fo time. They then are either removed or resorbed by the body. Permanent implants are those intended to remain th the body permanetyly.

what is biocompatibility?
|
The biocompatibility o f a material must consider both the hsot's response to amaterial and the pysiological effect of the environment on the materal
|
|
|
What are the two catergories of biocompatibility that are esesentioal in bomaterials.
|
Biologic biocompatibility relates tot he reaction of the hsot ot the impalnt. the material must not cause harm to the host tissue. MEchanical biociompatibility relates to the compatibility betweent he properties of the material and its intedned fungtion. The material must be able to perform in a manner thaat is a favorable to the tissue that it is enhancing or replacing.

Which caracteristics of a biomaterail or device can affect the host reposne to that material or implant?
|
The shape of a material or device can adversely effect the host reponse for instance a sdevice with sharp corners may be less cmpatible than a deviece with smoother contours. The size of a materal may also affect the biological resonse ot a materila or device. For instance , amaterial may have excellent biocomatibility in bulk form, but may elecit a sever response in partculate form. Finally the surface texture of a material or device may affect he hos treponse with tissue such as bone adhering to a textrued surgace.
