本实验利用我国生产的陶瓷材料,运用CAD—CAM CEREC系统制作同一标准模型MOD嵌体,与进口材料在同一设计下制作的嵌体就(牙合)面所标定的边缘的密合度在扫描电镜下,运用图像分析技术,比较各目的密合度。实验结果表明,国产材料在修复体边缘密合度方面与进口材料尚有差异。国产材料可以从陶瓷的晶体颗粒、收缩率等方面入手,进行配方及生产工艺的修改,以达到进口材料的性能。 In this experiment, the same standard model MOD inlay was made by using the ceramic material produced in China. The inlay of the inlay on the inlay was made under the same design with the imported material. Under the use of image analysis technology to compare the purpose of the closeness. The experimental results show that there is a difference between the domestic materials and imported materials in terms of the closeness of the edge of the prosthesis. Domestic materials from the ceramic crystal particles, shrinkage and other aspects of the start, the formulation and production process changes in order to achieve the performance of imported materials.
