Abstract:
1. Process for producing a prosthesis comprised of the: a1) taking of a precision impression of a patient's teeth and/or gums by means of an impression mass, b1) creation of a working model, c1) application to the working model of a base plate made of a light hardenable prosthesis material and subsequent hardening, d1) application of an insulating film on the base plate, e1) obtaining a tooth arrangement in wax on the insulated base plate to form a wax index, f1) molding an external framework of the teeth arches using an investment material; g1) boiling out of the wax index and removal of the insulation film; h1) filling of the hollow space resulting after the boiling out of the wax with the prosthesis material and subsequent hardening; or a2) taking of a precision impression of a patient's teeth and/or gums by means of an impression mass; b2) creation of a working model; c2) application to the working model of a base plate made of a light-hardenable prosthesis material and subsequent hardening; d2) obtaining a tooth arrangement in light-hardenable prosthesis material and subsequent hardening wherein said light hardenable prosthesis material is a composition comprised of 1. multifunctional urethane methacrylate/acrylate: 5-46 weight percent, 2. multifunctional, high-molecular acrylic resin: 2.5-20 weight percent, 3. multifunctional reactive dilution agent: 5-15 weight percent, 4. Bis-GMA and/or ethoxylated derivatives: 1-15 weight percent, 5. filler material: 2-15 weight percent, 6. organic filler material on PMMA/copolymer basis: 5-30 weight percent, 7. splinter polymerizate: 0-30 weight percent, 8. inorganic glass: 0-10 weight percent, 9. photoinitiator: 0.1-2 weight percent, and 10. color pigment: 0-1 weight percent.
