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, T (w) and setting, T (s) times) for BT 101 were shorter than the commercial GPCs. BT 101 also had a higher setting exotherm (S (x) -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, σ (c)), and 34, 54, and 62 MPa (biaxial flexural strengths, σ (f)), respectively. The strengths of BT 101 are more suitable for spinal applications than commercial GPCs.
玻璃聚烷酸酯水泥（GPCs）以前曾被考虑用于骨科应用。一种锌-GPC（BT 101）与具有类似于 BT 101 的凝固化学的商业 GPC（Fuji IX 和 Ketac Molar）进行了比较。BT 101 的操作性能（工作、T（w）和凝固、T（s）时间）短于商业 GPC。BT 101 的凝固放热（S（x）-34°C）也高于商业 GPC（29°C）。BT 101、Fuji IX 和 Ketac Molar 的最大抗压强度（σ（c））分别为 75、238 和 216 MPa，双轴弯曲强度（σ（f））分别为 34、54 和 62 MPa。BT 101 的强度更适合于脊柱应用，而不是商业 GPC。
