  • Process for preparing a paste from calcium phosphate cement
    Patent number: 6616742
    Abstract: A process for preparing a paste from calcium phosphate cement includes a) mixing an aqueous acidic solution and powder containing at least one of tricalcium phosphate and tetracalcium phosphate; and b) mixing the resulting mixture from step a) and an aqueous basic solution to form a paste. The calcium phosphate cement paste is useful in dental and bone prosthesis.

  • Process for producing fast-setting, bioresorbable calcium phosphate cements
    Publication number: 20030121450
    Abstract: A fast-setting, bioresorbable calcium phosphate cement is prepared by a process which can be carried out with a heat treatment up to 1000° C. on a mixture of a wetting solution and a calcium phosphate powder having a Ca to P molar ratio of 0.5-2.5. The wetting solution suitable for use in the process of the present invention includes water, an organic solvent, an acidic and basic solution. A setting solution for mixing with the heated powder to form the fast-setting, bioresorbable calcium phosphate cement may be water, an acidic or basic solution according to the process of the present invention.
