Abstract
The invention relates to an anterior tooth such as an incisor tooth or canine tooth built up in layers, with a cutting-edge material (30) at least partially covering a dentine material (28). At its occlusal end (38), the dentine material has projections (42) and/or irregularities (42, 46 and 48), which extend in the occlusal direction and correspond to 0.05 to 0.4 times the total length of a tooth.
Claims21
Sets of artificial teeth comprising a plurality of individual detached teeth, where each individual tooth of the plurality of individual detached teeth is built up in two layers consisting of a cutting edge material and a dentine material, with the cutting-edge material at least partially covering the dentine material, wherein the dentine material (28) comprises an occlusal end (38) having irregularities (42, 46 and 48), wherein a length of each of the irregularities extends in an occlusal direction and corresponds to 0.05 to 0.4 times a total length of the tooth, wherein the irregularities create an incisal dentine profile, and wherein the dentine material (28) has the irregularities (42, 46 and 48), at least in the occlusal end (38) of the dentine material (28), wherein a surface of the dentine material forms a boundary layer between the dentine material and the cutting-edge material, wherein the irregularities comprise fissures, incisions or trenches that are asymmetrical, wherein the incisal dentine profile is different in each tooth of the set of teeth, and wherein the irregularities have oblique surfaces having thicknesses and angles of inclination wherein values of the thicknesses of the irregularities and angles of inclination of the irregularities vary between individual teeth and between sets of teeth.
