Patent ID: 8454988

Claim:
A formable, self-hardening, poorly crystalline apatitic (PCA) calcium phosphate paste suitable for use as a bone implant material comprising: (a) a powder component comprising: (i) demineralized bone matrix (DBM) in an amount in the range of 25 to 70 wt %, wherein said DBM comprises particles having a particle size in the range of 53 μm to 850 μm; (ii) a calcium phosphate powder in an amount in the range of 25 to about 60 wt %; and (b) a physiologically-acceptable fluid in an amount to produce a cohesive, formable paste, wherein said paste retains its cohesiveness when introduced at an implant site in vivo and hardens to form a PCA calcium phosphate having a compressive strength in the range of 1 to 20 MPa.
