玻璃离子体粘固粉(以下简称玻璃粉)是一种有机和无机的共聚物,具有强度高、无毒、粘结性强等特点,为了使缺损的前牙及楔状缺损的患牙恢复生理形态和功能,我们采用玻璃粉充填患牙227颗,疗效尚为满意,现报道如下: 一、材料与调制本文所用玻璃粉系湖北省化学研究所参照国外有关资料研制而成,其主要成份为:①玻璃离子体粉末——由富含碱土金属钙离子的铝硅酸盐玻璃等组成;②50％的共聚酸水溶液——丙烯酸衣康酸共聚物;③5％酒石酸。
Glass ionomer cement (hereinafter referred to as glass powder) is an organic and inorganic copolymer, with high strength, non-toxic, strong adhesion and other characteristics, in order to make the defect of the anterior teeth and wedge-shaped defect of the teeth to restore physiology Morphology and function, we use glass powder filling teeth 227, the effect is still satisfactory, are reported as follows: First, the material and modulation Glass powder used in this article, Hubei Institute of Chemistry with reference to foreign information developed from the main components : ① glass ionomer powder - composed of aluminosilicate glass rich in alkaline earth calcium ion, etc .; ② 50% copolymer acid aqueous solution - acrylic acid itaconic acid copolymer; ③ 5% tartaric acid.
