At present, new acrylic plastic technologies are being developed in dentistry. Although this kind of material has been used for dental prostheses for over 80 years, it has been produced in the form of disks with the computer-aided design/computer-aided manufacturing (CAD/CAM) technology for over 15 years. The purpose of the article was to collect information from the literature on acrylic materials processed through the milling technology (CAD/CAM). The publicly available databases PubMed, Google Scholar and Scopus were searched using the key word "acrylic resins, CAD/CAM". All articles describing the application and testing of CAD/CAM disks were selected. Duplicate articles were removed. More than 100 articles that described the use of materials machined using the milling equipment were found. These included works comparing the mechanical properties, biocompatibility and clinical use of the materials. After the initial selection, 36 papers on this subject were included in this review. The number of studies on the processing of acrylic materials with the use of the CAD/CAM technology has been increasing worldwide. Since such materials have better mechanical properties, no polymerization shrinkage occurs during processing, the amount of residual monomer material is very low and they have better color stability than self-curing materials.
目前，牙科领域正在开发新型丙烯酸塑料技术。尽管这种材料已经用于义齿制作超过 80 年，但通过计算机辅助设计/计算机辅助制造（CAD/CAM）技术以圆盘形式生产也已经超过 15 年了。本文旨在从文献中收集有关通过铣削技术（CAD/CAM）加工的丙烯酸材料的信息。使用关键字“丙烯酸树脂，CAD/CAM”在公开可用的数据库 PubMed、Google Scholar 和 Scopus 中进行搜索。选择了所有描述 CAD/CAM 磁盘应用和测试的文章。删除重复的文章。找到了 100 多篇描述使用铣削设备加工的材料的应用文章。这些文章包括比较材料机械性能、生物相容性和临床应用的研究。经过初步筛选，共有 36 篇关于该主题的论文被纳入本次综述。使用 CAD/CAM 技术加工丙烯酸材料的研究数量在全球范围内不断增加。由于此类材料具有更好的机械性能，在加工过程中不会发生聚合收缩，残留单体材料的含量非常低，并且它们比自固化材料具有更好的颜色稳定性。
