一研究概述银汞合金是目前广泛应用于临床的一种较为理想的牙科充填材料。多少年来,银汞合金从配料到研磨全凭护士经验进行手工操作,所以,配料比例容易失常;研磨劳动强度大;慢性汞中毒发生率高。为了解决这些问题,我们从1971年开始,进行了银汞合金制备装置的研究。为了解决劳动强度问题,1971年初,口腔内科的同志首先提出了研制银汞合金研磨机的设想,并制定了有关方案。同年底便研制出了银汞合金电动研磨机,应用临床达12年之久。为了改进工艺,提高临床应用效
A study Overview Silver amalgam is currently widely used in clinical a more ideal dental filling material. For many years, silver amalgam from ingredients to grinding nurses based entirely on the experience of manual operation, so the proportion of ingredients prone to disorders; grinding labor intensity; high incidence of chronic mercury poisoning. In order to solve these problems, we started from 1971, a silver amalgam preparation device research. In order to solve the problem of labor intensity, in 1971, comrades of oral medicine firstly proposed the idea of developing amalgam grinding machine and formulated the relevant plan. At the end of the same year has developed a silver amalgam electric grinding machine, clinical application of up to 12 years. In order to improve the process, improve clinical efficacy
