Аннотация: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.
