The subject matter of the invention is a three-dimensional molded body, in particular a milling blank, made of a polymerizable prosthetic material, which is suitable for milling machining by means of CNC and/or CAD/CAM, having a fracture toughness of greater than or equal to 1.9 Mpa·m1/2 and a fracture work of greater than or equal to 900 J/m2. The milling blank preferably comprises core-shell particles modified by an elastic phase and is optionally based on a content of urethane (meth)acrylate polymerized into the polymer. Moreover, a subject matter of the invention is 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 of orthodontic appliances and instruments in medical field.
本发明的主题是一种由可聚合修复材料制成的三维模塑体,特别是铣削坯体,该坯体适用于通过 CNC 和/或 CAD/CAM 进行铣削加工,其断裂韧性大于或等于 1.9 Mpa-m1/2,断裂功大于或等于 900 J/m2。铣削坯料最好包括由弹性相改性的芯壳颗粒,并可选择基于聚合到聚合物中的氨基甲酸乙酯(甲基)丙烯酸酯含量。此外,本发明的一个主题是将铣削坯料用于生产牙科修复部件的至少一部分,如假牙、人造牙、牙桥,或医疗领域的正畸器具和器械。
