A novel strategy to enhance interfacial adhesion in fiber-reinforced calcium phosphate cement.
Calcium phosphate cements (CPCs) are extensively used as synthetic bone grafts, but their poor toughness limits their use to non-load-bearing applications. Reinforcement through introduction of fibers and yarns has been evaluated in various studies but always resulted in a decrease in elastic modulus or bending strength when compared to the CPC matrix. The aim of the present work was to improve...
متن کاملEvaluation of a prepared sol-gel bioactive glass fiber-reinforced calcium phos- phate cement
In this article 5-25 V% of a sol-gel bioglass fiber was incorporated into calcium phosphate bone cement to improve its mechanical properties. Compressive strength, work of fracture, elastic modulus and setting time of the cement were investigated as well as phase changes occurring during soaking the specimens in simulated body fluid (SBF). The cement microstructure was also observed by scanning...
متن کاملFiber reinforced calcium phosphate cements -- on the way to degradable load bearing bone substitutes?
Calcium phosphate cements (CPC) are well-established materials for the repair of bone defects with excellent biocompatibility and bioactivity. However, brittleness and low flexural/tensile strength so far restrict their application to non-load bearing areas. Reinforcement of CPC with fibers can substantially improve its strength and toughness and has been one major strategy to overcome the pres...
متن کاملPolylactide-co-glycolide fiber-reinforced calcium phosphate bone cement.
OBJECTIVE To compare the strength of polylactide-co-glycolide fiber-reinforced calcium phosphate bone cement (FRC) with nonreinforced calcium phosphate bone cement (NRC) subjected to simulated dural pulsations in defects larger than 25 cm(2). METHODS Seven NRC and 7 FRC specimens were set in both medium (37.5 cm(2)) and large (50.0 cm(2)) model skull defects while subjected to simulated dural...
متن کاملMechanical Properties of Poly(propylene fumarate) Reinforced Brushite Cement: Effects of Cement Composition and Powder to Liquid Ratio
Statement of Purpose: Calcium phosphate cements are prepared by mixing calcium phosphate powder with a liquid component to form a paste that hardens over time via a dissolution-precipitation reaction. Thus, in addition to being osteoconductive and resorbable, these biomaterials have the advantageous property of being injectable. This property can be leveraged for castingbased approaches to scaf...
