A biocompatible collagen/mineral composition which comprises a mixture containing 2-40% reconstituted fibrillar atelopeptide collagen and 60-98% calcium phosphate mineral by weight exclusive of moisture, which composition has a sterility assurance factor of at least as low as 10.sup.-6 and an additional characteristic selected from the group consisting of a compressive modulus of at least 10 N/cm.sup.2 and a tensile strength of about 3-12 N/cm.sup.2.
- 2. The composition of claim 1 which has a moisture content of 0.5-15 wt%.
- 3. The composition of claim 1 which has a collagen content of about 10-13%, and a calcium phosphate mineral content of about 82-90%.
- 4. The composition of claim 1 which has a collagen content of about 6-12%, and a calcium phosphate mineral content of about 78-89%.
- 5. The composition of claim 1 which further comprises an antibiotic.
- 6. A biocompatible collagen/mineral composition which comprises a mixture containing 2-40% reconstituted fibrillar atelopeptide collagen and 60-98% calcium phosphate mineral by weight exclusive of moisture, which composition has a sterility assurance factor of at least as low as 10.sup.-6 and an additional characteristic selected from the gruop consisting of a compressible modulus in the range of 25-45 N/cm.sup.2 and a tensile strength of about 3-12 N/cm.sup.2.
