Abstract
A composite material is provided including a strongly bioresorbable, poorly crystalline apatitic calcium phosphate composite and a supplementary material. The poorly crystalline apatitic calcium phosphate is characterized in that, when placed in an intramuscular or subcutaneous site, resorption of at least 1 g of the material is complete within one year. The supplementary material is in intimate contact with the hydroxyapatite material in an amount effective to impart a selected characteristic to the composite. The supplemental material may be biocompatible, bioresorbable or non-resorbable.
