Abstract
A dental prosthesis system includes at least one first and second dental prosthetic care part (1, 2) made of zirconium dioxide (ZrO2). Each of the two care parts has corner radii (R1, R11, R2, R22, R3, R26, R12, R13), and the corner radii (R1, R11, R2, R22, R3, R26, R12, R13) correspond to one another, wherein the first care part (1) is operatively connected to the second care part (2). At least one of the corner radii (R1, R11, R2, R22, R3) of the first dental prosthetic care part and/or the second dental prosthetic care part (R26, R12, R13) has a value of less than 0.1 mm, and the at least one corner radius (R1, R11, R2, R22, R3, R26, R12, R13) is produced by a material removal process using a laser method and/or by a machining process using a drill or a milling cutter made of full diamond.
