A study of the clinical application of bio-compatible cement CPC

牙科粘固剂的使用是牙科临床治疗中最重要的性能之一。研究了不同外加剂对生物相容水泥性能的影响。近年来，我们对水泥粉的粒径分布与操作性能之间的关系进行了研究。首先，研究了常规牙科粘结剂的粒径分布、粘结度与操作性能的关系。因此，水泥粉的粒径分布不仅对水泥的操作性能有很大的影响，而且对胶膜厚度也有很大的影响。此外，通过扫描电子显微镜观察发现，水泥粉颗粒的形状也会影响操作。

Handling of dental cement is one of the most important properties for application for dental clinical therapy. We have investigated the influence of various additive agents on the handling of bio-compatible cement. Current year, we investigated about correlation between distribution of the particle diameter of cement powder and handling properties.First, the distribution of the particle diameter of conventional dental luting cement, and the degree of viscosity of cement and the relation of handling properties were investigated. Consequently, the distribution of particle diameter of cement powder is to which influencing greatly became not only cement handling properties but film thickness clear.Moreover, it was suggested as a result of SEM observation that the form of a cement powder particle also affects handling.
