Abstract

Wear of a glass-ceramic produced through controlled crystallization of a glass in the MgO-CaO-SiO2-P2O5-F system has been evaluated and compared to various commercial dental ceramics including IPS Empress 2, Cergo Pressable Ceramic, Cerco Ceram, and Super porcelain EX-3. Wear tests were performed in accord with the ASTM G99 for wear testing with a pin-on-disk apparatus. The friction coefficient and specific wear rate of the materials investigated were determined at a load of 10 N and at ambient laboratory conditions. Microhardness of the materials was also measured to elucidate the appropriateness of these materials for dental applications.

mgo - cao - sio2 - p2o5 - f基玻璃陶瓷与选定牙科陶瓷的磨损比较

通过在MgO-CaO-SiO2-P2O5-F体系中控制玻璃结晶生产的玻璃陶瓷的磨损进行了评估，并与各种商用牙科陶瓷(包括IPS Empress 2, Cergo Pressable Ceramic, Cerco Ceram和Super porcelain EX-3)进行了比较。磨损试验按照ASTM G99使用针盘式设备进行磨损试验。在10 N载荷和环境实验室条件下测定了所研究材料的摩擦系数和比磨损率。还测量了材料的显微硬度，以阐明这些材料在牙科应用中的适用性。
