Abstract
Methods of producing a composite block intended for the production of a dental prosthesis including the following steps: a) impregnating a porous support with a liquid resin and b) curing the liquid resin impregnating the support are provided. In such methods of producing a composite block intended for the production of a dental prosthesis, a volume of liquid resin that is greater than the volume of the open pores of the support by at least 2% is caused to penetrate into the support and to cure therein, said volumes being measured at a temperature of 20° C. and at a pressure of 1 bar.

A method of producing a composite block intended for the production of a dental prosthesis, said method comprising the following steps:
- a) infiltrating a porous support made in a material with a quantity of a liquid resin;
- and
- b) curing the liquid resin impregnating the support, wherein, in step b), the liquid resin is subjected to a pressure of more than 300 bar,
- wherein the pressure and a difference in compressibility between the material of the porous support and the liquid resin makes a volume quantity of the liquid resin infiltrated into the porous support exceed the volume of open pores of the porous support by greater than or equal to 2%, the volumes of the liquid resin and of the open pores being measured at a temperature of 20° C. and a pressure of 1 bar.
