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 33, 34 which are mounted in an oral cavity as a dental prosthetic appliance, an occlusal surfaces of the teeth 1, 2, 5, 6 are provided with side grooves 29 to 32 extending toward a buccal side or lingual side, and intersecting portions (tops 29a to 32a) of the side grooves 29 to 32 with the outer circumference of the occlusal surface, and a contact point 35 are formed on a plane parallel to the mesical distal direction. Or the teeth 1, 2, 5, 6 are configured such that the bottom ends of fossae 25, 27 on the occlusal surface and the contact point 35 are formed on a plane parallel to the mesical distal direction. Alternatively, mutually parallel flat frictional contact portions 9 to 12 are provided around cusps 13A, 13B to 16, 17A, 17B to 20 mutually contacting with maxillary molar teeth 1, 2 and mandibular molar teeth 5, 6, respectively.
