Abstract
A calcium phosphate monetite cement-forming composition comprises a monetite-forming calcium-based precursor powder and from 3 to 30 wt %, based on the weight of the precursor powder, of dicalcium pyrophosphate powder. Monetite cements formed form such compositions may be used in implants for correcting bone defects. Methods for bone defect repair employ implants formed from such monetite cements and slow implant resorption and/or improve in vivo bone induction in a patient.
