Abstract:
A structure of, and a method of producing, a biocompatible structure for bone and tissue regeneration are disclosed. The method includes dissolving a polyurethane polymer in methanol, adding hydroxyapatite (HAP) nanoparticles to form a uniformly distributed mixture, applying the mixture to a polytetrafluoroethylene (PTFE) surface to form a polymer film, cutting the polymer film into strips, stacking the strips with layers of bone particles disposed therebetween, coating the stacked strips and layers by the mixture and allowing it to dry, adding bone particles to the coating, and plasma treating the structure to form the biocompatible structure. A weight percentage of the HAP nanoparticles to the polymer is about 5-50% such that a resorption rate of the biocompatible structure substantially matches a rate of tissue generation in the biocompatible structure.
