本文讨论了磷酸锌、聚羧酸锌和玻璃离子水门汀的强度、固位力、膜厚、工作时间、溶解度、早期水敏性、生物相容性和操作性能。磷酸锌粘固剂具有良好的强度、使用时间和生物学性能。它很容易处理，即使在混合大量的时候也是如此。聚羧酸盐水泥强度较低，流动性不同，工作时间较短，但具有良好的生物相容性。聚羧酸盐粘固剂是一种替代方法，在咀嚼过程中，预计会发生牙髓反应，修复体上的负荷有限。玻璃离子水门汀具有最高的强度和固位性能，但溶解度较低。溅射困难，工作时间短，固化过程中与水的接触对材料表层的质量至关重要。玻璃离子水门汀的生物学性能与磷酸锌水门汀相似。它是磷酸锌粘固剂的替代品，在这种情况下不可能获得正常的固位力。
The paper discusses strength, retention, film thickness, working time, solubility, early sensitivity to water, biocompatibility and handling properties of zinc phosphate, polycarboxylate and glass ionomer cements. Zinc phosphate cement has acceptable strength, working time and biological properties. It is easy to handle, even when mixing large quantities. Polycarboxylate cement has less strength, different flow properties and a shorter working time, but excellent biocompatibility. The polycarboxylate cement is an alternative where pulp reactions are expected to occur and the load on the restoration during mastication is limited. Glass ionomer cement has the highest strength and retentive properties and a low solubility. It is difficult to spatulate, the working time is short, and contact with water during setting is critical for the quality of the surface layer of the material. The biological properties of glass ionomer cements are similar to those of zinc phosphate cements. It is an alternative to zinc phosphate cement where normal retention is impossible to obtain.
