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.

咀嚼介质组分;纤维和磨粒对牙科材料中最硬的材料--牙科陶瓷的磨损有影响。当磨料颗粒与5%的纤维素结合时，陶瓷的磨损显著增加，这是预期通过增加介质的粘度来减少磨损。在本实验条件下，陶瓷的磨损量随磨粒含量的增加而减小。因此，在某些情况下，咀嚼介质的成分对瓷的磨损有相反的影响。
