Wear of dental porcelain and antagonist under mastication with fiber and abrasive particle

咀嚼介质的组成；牙瓷是牙科材料中最硬的材料，纤维和磨料颗粒对牙瓷的磨损有影响。当磨料颗粒与5%的纤维素混合时，陶瓷的磨损大大增加，预期通过增加介质的粘度来减少磨损。相反，在实验条件下，随着磨料颗粒的增加，陶瓷的磨损减小。因此，在某些情况下，咀嚼介质成分对瓷的磨损表现出相反的影响。

Components of mastication mediums; fiber and abrasive particle, affected on wear of dental porcelain which is the hardest material in dental materials. Wear of porcelain increased substantially when abrasive particle was combined with 5 % cellulose which was expected to reduce wear by increasing a viscosity of medium. On the contrary, wear of porcelain decreased by increasing of abrasive particle according to experimental condition. Thus components of mastication medium showed inverse effect on wear of porcelain in some situation.
