Abstract
The invention relates to a method for the production of blocks of material of a polymerized dental composite material as well as to the blocks of material obtainable according to the method, in which (i) a polymerisable dental composite material is transferred into a pressure-resistant casting mould (100), (ii) a pressure in the range of 10 to 500 MPa is applied to the polymerisable dental composite material in the pressure-resistant casting mould, and (iii) at least a part of the casting mould and/or the polymerisable material is heated in a defined manner to a temperature of 90 to 150° C.
Claims17
A method for the production of at least one block of material (3) of a polymerized dental composite material, in which
- (i) a polymerisable dental composite material is transferred into a pressure-resistant casting mould (100),
- (ii) a pressure in the range of 10 to 500 MPa is applied to the polymerisable dental composite material in the pressure-resistant casting mould,
- (iii) at least a part of the casting mould as well as the polymerisable material are heated in a defined manner to a temperature of 90 to 150° C.
- wherein the polymerisable dental composite material in the pressure-resistant casting mould is hot isostatically pressed and polymerized, wherein the polymerization front is substantially perpendicular to the vector of force (N).
