description The invention relates to a dental blank (1) in the form of a three-dimensional shaped body for producing a dental restoration (10), comprising a preform (3), wherein the preform (3) has a base surface (31), and a top surface (32) lying opposite the base surface (31), and also a first lateral surface (33A) and at least one further lateral surface (33B, 33C, 33D), wherein a lumen (4) is formed inside the preform (3) and extends from the base surface (31) in the direction of the top surface (32) as far as a point (P) located between the base surface and the top surface, and the point (P) is at the distance (d1) from the base surface and at the distance (d2) from the top surface, and the ratio d1 to d2 is in the range of 1: 1 to 10: 1. The invention further relates to a method for producing the dental blank and to the use of the latter in a subtractive manufacturing method for producing a dental restoration.
