Аннотация доклада:
The creation of tissue engineering constructions for bone implants involves the creation of biocompatible biodegradable porous inorganic calcium phosphate matrix. Composite materials in the system СаО-Р2О5 can be used for creation of the porous matrix. Phase composition of ceramic material can include biodegradable phase of calcium polyphosphate (Са(РО3)2)n (PolyCP), calcium pyrophosphate Ca2P2O7 (PyroCP) and tricalcium phosphate Ca3(PO4)2 (TCP) in different proportions. These calcium phosphates have different solubility. Therefore, PolyCP, PyroCP and TCP are characterized by a different propensity to biodegradation. PolyCP (Ca/P=0,5) has the greatest speed of biodegradation, and TCP (Ca/P=1,5) has the smallest speed of biodegradation mentioned above calcium phosphates. PyroCP occupies an intermediate position (Ca/P =1). The aim of this work was to obtain ceramic composite materials containing such resorbable phases as PolyCP and PyroCP.
