Reconstruction of calvarial bone defects using poly(amino acid)/hydroxyapatite/calcium sulfate composite

The aim of this study was to evaluate the thermal properties and in vivo interface performance of poly(amino acid) (PAA) and a composite containing PAA, hydroxyapatite (HA), and calcium sulfate (CS), with respect to their suitability for skull repair. Biocompatibility was evaluated by implantation of materials into muscles of rabbits for eight weeks. Skull repair was assessed by implanting PAA, the compact PAA/HA/CS composite (c-PAA/HA/CS), and...
