玻璃离子体粘固粉是近代发展起来的一种新型齿科充填材料。它主要是由富含碱土金属钙离子的铝硅酸盐玻璃所组成,能与有机聚合酸结合固化,与原有齿科材料如银汞合金,磷酸锌粘固粉相比,不仅在使用上方便,而且具有凝结时间快、强度大、有韧性、耐磨、无毒、稳定性良好等特点。因此,受到了口腔 Glass ionomer cement is a new type of dental filling material developed in modern times. It is mainly composed of aluminosilicate glass rich in alkaline earth calcium ions, can be combined with organic polymeric acid curing, compared with the original dental materials such as silver amalgam, zinc phosphate cement, not only in use Convenient, but also with the setting time, strength, toughness, wear resistance, non-toxic, good stability and so on. Therefore, by the mouth
