Abstract
Processes for the preparation of compositions used in conductive bone repair are disclosed. The compositions contain a mixture consisting essentially of either a calcium phosphate particulate mineral component or particulate hydroxyapatite in admixture with atelopeptide reconstituted fibrillar collagen. The method is comprised of mixing a dispersion of the collagen and mineral, the latter which is present in dry particulate form, followed by molding and drying the composition in a mold to obtain a dried composition.
