Abstract

The invention relates to a method for producing a plastics body with patterned layers for producing dental prostheses having the steps:

method for production, wherein the method is characterized by the following steps:A) providing a first and a second PMMA-based compound which are uncured and have different colorations;B) heating of a first patterned pressing surface to between 90° C. and 150° C.;C) pressing of the first PMMA-based compound with the heated first pressing surface, such that a patterned surface of the first PMMA-based compound is obtained;D) detachment of the first pressing surface;E) heating of the first or of a second patterned pressing surface to between 90° C. and 150° C.;F) pressing of the second PMMA-based compound with the heated pressing surface, such that a patterned surface of the second PMMA-based compound is obtained;G) detachment of the pressing surface;H) subsequent laying of the patterned first and second PMMA-based compounds on one another such that the patterned surface of the second PMMA-based compound is oriented toward the patterned surface of the first PMMA-based compound; andI) compression molding of the first with the second patterned PMMA-based compound, such that a solid bond is created between the first PMMA-based compound and the second PMMA-based compound.
