本文研究了一种新的齿科充填用复合材料的制备方法,并测定了复合材料的性能.研究结果表明,这种新型的复合材料比常规的高分子齿科材料具有硬度高、耐磨性好、粘结强度大和线膨胀系数小等优点. In this paper, a new preparation method of composite for dental filling was studied, and the properties of the composite were measured.The results show that the new composite has higher hardness and wear resistance than the conventional polymer dental materials Good, bond strength and linear expansion coefficient of small advantages.
