The invention enables to arrange teeth at appropriate positions depending on the oral cavity environment of each patient without requiring advanced techniques or experiments. In artificial molar teeth to be arranged on bases which are mounted in an oral cavity as a dental prosthetic appliance, an occlusal surfaces of the teeth are provided with side grooves extending toward a buccal side or lingual side, and intersecting portions (tops) of the side grooves with the outer circumference of the occlusal surface, and a contact point are formed on a plane parallel to the mesial distal direction. Or the teeth are configured such that the bottom ends of fossae on the occlusal surface and the contact point are formed on a plane parallel to the mesial distal direction. Alternatively, mutually parallel flat frictional contact portions are provided around cusps mutually contacting with the maxillary molar teeth and the mandibular molar teeth, respectively.
