Static mechanical properties of acrylic bone cements containing an organobismuth compound as a radiopacifier

The inclusion of triphenyl bismuth (TPB) as an alternative radiopacifier in bone cements with good tensile properties was reported. Using Servohydraulic Testing Machine in accordance with ISO 5833 standard using cylindrical specimens where the ratio of the length to the diameter is 2:1, the compression testing was performed. It was observed that the addition of TPB does not degrade the flexural or compressive strengths of acrylic cements. It was shown that the ultimate compressive strengths of TPB-cements exceeded the minimum value of 70 MPa stated by ISO 5833 fro acrylic cements
