【Abstract】 Objective To characterize the hardness of the new developed dental machinable ceramic. Method Indentation method was used, and the Vickers hardness of four groups of the new developed ceramic were recorded. Result The Vickers hardness of four groups of the new developed ceramic were among the range of(645.6-658.4)kgf.mm-2. Conclusion The hardness of the new developed dental machinable ceramic was similar with that of the traditional dental glass-ceramics.更多还原
