Abstract

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.
