整个80年代,国外口腔材料的研究较为活跃,特别是口腔高分子材料有了较快的发展.进入90年代,这种发展势头依然不减,并有望在今后的几年中有新的突破.综合各方面的信息来看,美国在这一领域一马当先,其所发表的有关文献和专利约占全世界总量的一半.紧随其后的有英国、日本、加拿大、瑞典、丹麦、澳大利亚、德国等发达国家.下面将依据不同的应用情况,分类予以总结. Throughout the 1980s, foreign oral material research is more active, especially oral polymer material has developed rapidly into the 90's, this momentum of development is still diminished, and is expected in the next few years there are new breakthroughs. According to the information of all fields, the United States takes the lead in this field with about 50% of the world's total published literature and patents, followed by the United Kingdom, Japan, Canada, Sweden, Denmark, Australia, Germany and other developed countries.The following will be based on different applications, classification is summarized.
