Material (A) for dentures, having a 3-point bending strength of 1300 MPa, is claimed. Independent claims are included for: (1) a preform for the production of a denture； (2) a set of preforms, preferably preforms from the same preform body, where all the preforms of the set is transformed by sealed sintering such that they exhibit a 3-point bending strength of at least 1300, 1400, 1500, 1600, 1700, 1800, 1900 or 2000 MPa； (3) the manufacture of preform bodies or preforms for the production of dentures, comprising pressing a powder with an isostatic or uniaxial, biaxial or triaxial pressing pressure of at least 1500 bar； and (4) the manufacture of a denture component comprising producing preforms or preform bodies and subsequently producing preforms or providing the preforms or a set of preforms, machining the preforms to mold one or more dentures, for example by mill-cutting.
