Abstract:
Two-component bone cement comprising A) a paste as component A, comprising a1) methylmethacrylate; a2) at least one methylmethacrylate-soluble polymer having a number average molar mass of less than 500,000 Dalton; a3) at least one methylmethacrylate-insoluble particulate polymer having a particle size D50 of less than 50 μm; a4) at least one methylmethacrylate-soluble hydroperoxide; and a5) at least one methylmethacrylate-soluble tertiary amine; and B) a powder as component B, comprising b1) at least one particulate radiopaquer having a particle size D50 of less than 50 μm; b2) at least one methylmethacrylate-soluble heavy metal salt; and b3) at least one methylmethacrylate-soluble reducing agent.The mixing of paste A and powdered component B immediately generates a tack-free plastically deformable cement dough, without any waiting time, that self-cures by means of radical polymerization.
