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.
