Craniomaxillofacial surgery or accidental injury frequently results in large bony defects requires the bone grafts to enhance the bone healing. 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.

口腔及颅颜外科手术或意外伤害时，倘若造成大范围之骨缺损，常因愈合不易而需要进行骨移植术加速骨的愈合，目前虽有氢氧磷灰石，磷酸钙与硫酸钙合成骨替代物等选择，但这些产品操作及固化时间长、不易塑形、抗张力与抗剪切力较低，而造成手术时间变长，因此本研究目的在研发一种新型且操作便利，可快速塑形，符合组织工程原理，应用於骨缺损的骨？
