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

牙科粘固剂的处理是牙科临床治疗应用中最重要的性能之一。我们研究了各种添加剂对生物相容性水泥处理的影响。本年度，我们对骨水泥粉末的粒径分布与操作性能的相关性进行了研究。首先，对传统牙科用粘接剂的粒径分布、粘固剂的粘度与操作性能的关系进行了研究。因此，水泥粉末的粒径分布不仅对水泥的操作性影响很大，而且对膜厚的影响也很大。此外，根据SEM观察的结果，水泥粉末的颗粒形状也对操作性产生影响。

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.
