Compatibility of Bioceramics with the Physiological Environment
When prosthetic materials are placed in the body, consideration must be given to (1) the effect of the physiological environment upon the prosthetic metal, medical polymer, or bioceramic, and (2) the effect of the prosthetic material and its corrosion or degradation products upon the fluids and tissues of the surrounding environment. The interaction which occurs between biomedical materials and the physiological environment is discussed with emphasis on the mechanism of biocorrosion, biodegradation, and wear as well as on the toxicology of implant materials. Since bone and soft tissue invade certain physiologically acceptable porous ceramic materials, there is reason for optimism that ceramics will become very useful materials of construction for orthopedic and oral appliances.
