    Type: Grant
    Filed: October 5, 1995
    Date of Patent: December 9, 1997
    Inventor: Michele Tyszblat Sadoun
  • Completely ceramic dental prosthesis based on alumina/magnesia spinel and a process for its manufacture
    Patent number: 5447967
    Abstract: The invention relates to a biocompatible ceramic dental prosthesis having a translucency similar to that of natural tooth enamel and a high mechanical strength.It comprises a rigid, porous infrastructure obtained by the reactive calcination of fine particles of alumina/magnesia spinel, alumina and magnesia, the pores of which are occupied by glass infiltrated at high temperature.The invention also relates to a manufacturing process for producing such a prosthesis.
    Type: Grant
    Filed: October 7, 1993
    Date of Patent: September 5, 1995
    Inventor: Michele Tyszblat
  • Process for the preparation of a dental prosthesis and the prosthesis produced by said process
    Patent number: 5250352
    Abstract: A ceramic dental prosthesis is produced from a shaped fritted metal oxide infrastructure whose pores are filled with a glass.
    Type: Grant
    Filed: February 11, 1991
    Date of Patent: October 5, 1993
    Inventor: Michele Tyszblat
  • Process for the preparation of a dental prosthesis by slight solid phase fritting of a metal oxide based infrastructure
    Patent number: 4772436
    Abstract: A method for manufacturing a dental prosthesis from a shaped, slightly solid phase fritted metal oxide infrastructure whose pores are impregnated with a glass by molding a tooth model from a linearly expanding molding mass and contacting the model with a slip of metal oxide particles which particles are agglomerated onto the model. The agglomerated metal oxide particles forming an infrastructure which is shaped and baked to effect dehydration and withdrawal of the model from the infrastructure before the fritting and glass impregnation of the infrastructure.
