N2 - Glass polyalkenoate cements (GPCs) have previously been considered for orthopedic applications. A Zn-GPC (BT 101) was compared to commercial GPCs (Fuji IX and Ketac Molar) which have a setting chemistry analogous to BT 101. Handling properties (working, Tw and setting, Ts times) for BT 101 were shorter than the commercial GPCs. BT 101 also had a higher setting exotherm (Sx - 34 °C) than the commercial GPCs (29 °C). The maximum strengths for BT 101, Fuji IX, and Ketac Molar were 75, 238, and 216 MPa (compressive, σc), and 34, 54, and 62 MPa (biaxial flexural strengths, σf), respectively. The strengths of BT 101 are more suitable for spinal applications than commercial GPCs.
