Abstract:
Polymer containing calcium sulfate particles as an implant material are provided. The polymer containing calcium sulfate particles include a calcium sulfate compound coated with a therapeutic polymer containing salicylate, with a coating thickness from about 2 μm to about 50 μm. The therapeutic polymer in the particles is in a range from about 0.1% to about 22% (w/w). The resorption of the particles in vivo is from about four weeks to about twenty weeks. The polymer containing calcium sulfate particles can be used as an implant material for bone repairing and bone augmentation.
