Synthetic bone substitutes such as hydroxyapatite, tricalcium phosphate and calcium sulfate have shortcomings in the sense that they have prolonged working and setting time, poor strain, shear strength and not easily shapeable. Therefore, the purpose of this study is to develop a novel, convenient and easily shapeable bone graft that is composed of poly-lactic acid and polycaprolactone as the matrix and calcium sulfate as the filler.
