| abstract |
The invention relates to a three-dimensional molded body, in particular a milling blank made of a polymeric prosthesis material which is suitable for a milling machining by means of CNC and / or CAD / CAM, with a fracture toughness of greater than 1.9 MPa ยท m 1/2 and a Breaking work greater than or equal to 900 J / m 2 has. The mill blank preferably comprises core-shell particles modified by an elastic phase and optionally based on a content of copolymerized urethane (meth) acrylate. The invention further relates to the use of the milling blanks for the production of at least parts of dental prosthetic parts, such as a prosthesis, artificial teeth, bridges, or even of orthodontic appliances and instruments in the medical field. |
