在工业学大庆,农业学大寨的高洲中,为了适应新形势的发展,有利于抓革命促生产,我们根据国外口腔医院杂志1974年1、2、3、4期有关环氧树脂、复合树脂等高分子化合物的研究资料和在口腔科的运用原理,开始试验用于固定桥牙修复上。利用它在常温下的快速凝固,与骨折部位粘合起固定作用,持续粘着 In the Daqing Industrial Science, agriculture Dazhai in the high, in order to adapt to the new situation, is conducive to grasp the revolution and promote production, according to the Foreign Stomatological Hospital in 1974 1,2,3,4 period on the epoxy resin, composite resin Such as polymer research materials and the use of dental theory, began to test for the repair of the bridge on the bridge. Use it at room temperature rapid solidification, and fracture site adhesion play a role in the fixed, continuous adhesion
