The present invention provides artificial teeth of upper and lower jaws
pairing between the cusp tips and pits, allowing to operate the
arrangement easily by clarifying the three-dimensional positional
relation of cusp tips and pits to contact with each other in occlusion
and the contact region. In an artificial tooth of a mandibular first
premolar tooth having a buccal cusp tip, a lingual cusp tip, a mesial
pit, and a distal pit, the azimuth originating from the distal pit, the
ratio of distance to the mesial surface, distal surface, buccal surface,
and the lingual surface, and the positional relation of the cusp tips and
pits are set appropriately. Further, in an artificial tooth of a
maxillary first premolar tooth having a buccal cusp tip, a lingual cuts
point, a mesial pit, and a distal pit, the azimuth originating from the
lingual cusp tip, the ratio of distance to the mesial surface, distal
surface, buccal surface, and the lingual surface, and the positional
relation of the cusp tips and pits are set appropriately. The distal pit
of the artificial tooth of the mandibular first premolar tooth is made to
contact with the lingual cusp tip of the artificial tooth of the
maxillary first premolar tooth, and the buccal cusp tip of the artificial
tooth of the mandibular first premolar tooth is made to contact with the
mesial pit of the artificial tooth of the maxillary first premolar tooth.
