- Abstract
The article compares different materials of bone substitutes – bioceramics: hydroxyapatite (HA), tricalcium phosphate (CaP) and polymer: polylactide (PLA). In the paper determines which of the substitutes is mechanically similar to the natural bone. Universal testing machine for tensile, compression was used for research. The properties of the test substances were determined by a compression and hardness test. Comparative tests are conducted with HA, CaP, PLA which were kept for 3 weeks in physiological saline and with natural pig bone. The mechanical properties of PLA specimens produced by 3D printers have been found to be similar to natural bone. When held in saline, PLA does not change its properties and dissolves less quickly than tricalcium phosphate.
