自1973年以来,临床上一直采用丙烯酸树酯作为可摘义齿的牙托材料,但由于工艺繁琐,制作周期较长,远远不能满足临床需要。近年来合成高分子技术有了很大发展,国内外都在研究用它做新的牙托材料,如尼龙、聚碳酸脂、甲基丙烯酸甲脂等。但因性能上有一定缺欠,仍未被广泛采用。 Since 1973, acrylic resin has been used clinically as a removable denture denture material, but due to cumbersome process, the production cycle is longer, far from meeting clinical needs. In recent years, synthetic polymer technology has made great progress, both at home and abroad are using it to do new dental materials, such as nylon, polycarbonate, methyl methacrylate and so on. However, due to lack of performance, it has not been widely used.
