Gamma irradiation of collagen/mineral mixtures

摘要

A biocompatible collagen/mineral composition which comprises a mixture of 2-40% reconstituted fibrillar atelopeptide collagen and 60-98% calcium phosphate mineral by weight, exclusive of water, is disclosed. The composition has a sterility assurance factor of at least as low as 10-6 and either a compressive modulus of at least 10 N/cm-2 or a tensile strength of about 3-12 N/cm-2.
