The invention relates to a tooth replacement including at least one posterior tooth having a mesial contact surface, a distal contact surface, and an occlusal surface. The occlusal surfaces includes at least one buccal cusp having a buccal cusp tip, a lingual cusp having a lingual cusp tip, a central fissure which has at least one tooth pit and passes through the occlusal surface in the mesiodistal direction between the two cusps, a first gradient which slopes downward from the buccal cusp tip in the direction of the central fissure, and a second gradient which slopes downward from the lingual cusp tip in the direction of the central fissure. The tooth replacement according to the invention is characterized in that the mesial contact surface, the distal contact surface and/or the occlusal contact surface comprise expansion spaces that have been incorporated in a targeted manner to obtain a dynamic occlusal guidance.

Digitally designing artificial teeth for use in a dental prosthesis and/or dental restoration. Designing natural-looking functional artificial teeth based on computer-aided design using reference dentition articulated in a predetermined occlusal scheme as a basis for effective design. In particular, the occlusal surfaces of posterior artificial teeth are designed in a digital environment to provide effective consistent functional set-up and performance, especially across a variety of occlusal schemes, in the preparation of dental prostheses.

A set of artificial teeth for a denture comprises a maxillary unit and a mandibular unit. When set up in lingualised occlusion or balanced occlusion, at least one of following occurs: the palatal cusp (1a) of the maxillary posterior tooth (7a) fits into the distal fossa (1b) of the mandibular posterior tooth (8a); the palatal cusp (2a) of the maxillary posterior tooth (7b) fits into the distal fossa (2b) of the mandibular posterior tooth (8b); the mesial palatal cusp (3a) of the maxillary posterior tooth (7c) fits into the central fossa (3b) of the mandibular posterior tooth (8c); the distal palatal cusp (4a) of the maxillary posterior tooth (7c) fits onto the marginal ridge (4b) of the mandibular posterior tooth (8c); and the mesial palatal cusp (5a) of the maxillary posterior tooth (7d) fits into the central fossa (5b) of the mandibular posterior tooth (8d).
