| 摘 要： | 按牙科陶瓷国际标准ISO6872推荐标准对一种新型的牙科计算机辅助设计加工(CAD/CAM)陶瓷进行了体外表面抗腐蚀性研究．该材料表现出与其他牙科陶瓷相同的现象，在玻璃相出现孔洞，这些孔洞在负载时成为破坏的起点，导致材料强度降低． |

| Abstract: | The objective of this study was to evaluate possible changes of a new-type dental CAD/CAM machinable glass-ceramic in a provocative corrosive environment according to ISO 6872. After contacted with the corrosive environment, observed by SEM, the exposed surface was covered in fewer voids in the part of glass phase, which is similar to other dental ceramics. These voids initiate damage while loading, thus the strength decreased. |
