摘要
目的比较玻璃离子水门汀和自凝塑料固化后的硬度差别,对使用玻璃离子水门汀制作固定式牙合垫进行初步研究。方法分别制作自凝塑料和玻璃离子水门汀的试样,测试两种材料的维氏硬度。结果玻璃离子水门汀的平均硬度高于自凝塑料,但硬度参数范围较大。结论玻璃离子水门汀的硬度完全适合于制作固定式牙合垫。
Objective To compare the different hardness between room temperature curing denture base resin and glass ionomer cement,and to explore the method making fixed occlusion pad with glass ionomer cement.Methods The glass ionomer cement and autopolymerizing acrylic resin were made.The specimens Vickers hardness was tested by microscopic hardness meter.Results The average hardness of glass ionomer cement was higher than that of the autopolymerizing acrylic resin.Conclusion Glass ionomer cement is able to make fixed occlusion pad.
