As previously reported,'q2 a polymer-ceramic composite designed for endosseous implant applications has been developed. The composites were prepared by the free-radical polymerization of an acrylic acid solution and a difunctional acrylate in the presence of 0.3 pm akunina powder. Mechanical testing indicated that the material had a compressive yield strength of 89-102 MPa (13-15 ksi) and an elastic modulus of 2055-2740 MPa (300-400 ksi). The average porosity of the composite was determined to be in the range…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
