Abstract:

BACKGROUND: Currently, high-strength, lightweight polymer materials were mainly used to create prosthetic components. Thermoplastic sheet, resin-based composite materials, and low-temperature thermoplastic materials are used most widely.
OBJECTIVE: To analyze the tribology and biocompatibility of polymer materials as prosthetic materials commonly used with the human skin.
METHODS: Wanfang database was searched by the author for articles about prosthetic materials and their friction and biocompatibility with human skin published from 1990 to 2008.
RESULTS AND CONCLUSION: Polyethylene, polypropylene and other thermoplastic polyester sheets, low-temperature hot-plate materials, silicone rubber, titanium, etc., all have a good biocompatibility with human skin, but they have their own advantages and disadvantages on the tribology with human skin. In the future, based on molecular biology and toxicology, we should continuously improve prosthetic material biocompatibility, further explore the friction behavior under physiological conditions, find a reliable theoretical basis for in vitro experiments, and design a better prosthesis model to achieve the bionic effect.
