BONE PROSTHESIS MATERIAL AND METHOD FOR PREPARING IT Russian patent published in 2012 - IPC A61L27/12 A61L27/20 A61L27/02 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. What is described in a method for preparing a bone prosthesis material which involves producing precursor particles of tricalcium phosphate (TCP) particles; pre-caking the TCP-particles at temperature within the first temperature range to produce the TCP-particles of the diameter within the preset diameter range range; granulating the TCP-particles and caking the granulated bodies at temperature within the second temperature range. The second temperature range includes temperatures exceeding those of the first temperature range. A first gap 100 to 400 mcm is formed in the bone prosthesis material between two caked particle group neighbours. Each caked particle group contains the tricalcium phosphate (TCP) particles which are caked to form a second gap 5 to 100 mcm between two TCP neighbours. The first gap and the second gap are connected. Each caked particle group has a connection portion connecting the TCP-particle, and said connection portion is 5 to 20 mcm wide.

EFFECT: using the bone prosthesis material enables bone regeneration in a short time.
