  • A novel polymer infiltrated ceramic for dental

    2011-5-26 · Phantom teeth have E and H values similar to those of carious dentine, that is, one-sixth to one-tenth of the values for sound enamel. In contrast the polymer infiltrated ceramic has higher E and H than sound dentine. Regarding the fracture toughness, both synthetic materials have similar values to enamel and a lower value than dentine.
