| 摘要 |
The present invention relates to a metal oxides based glass for the impregnation of an open pore sintered infrastructure composed of particles of at least one metal oxide for the manufacture of ceramic dental prostheses, characterized by the fact that it comprises principally from 40 to 50% by weight of lanthane oxide (La2O3), from 5 to 15% by weight of ytterbium oxide (Yb2O3), and from 35 to 55% by weight of other metal oxides, excluding calcium oxide (CaO). |
