Abstract
A hydraulic cement for biomedical applications. The cement sets in-situ, hardening when exposed to water to produce nano-dispersed composite of calcium-silicate-hydrate gel mixed with hydroxyapatite. In comparison with prior cements, the composition provides high biocompatibility, high bioactivity and high biomechanical strength, due to the composite structure of the calcium silicate hydrate reinforced with co-precipitated particles of hydroxyapatite. Biocompatibility is also increased due to an absence of aluminum and magnesium in the composition. The cement is suitable for variety of applications, including dental implants, bone fixation, and bone repair.
