A set of artificial teeth allows for easy occlusion adjustment without high precision in arrangement. One of a pair of occluding upper and lower artificial molar teeth has convex adjustment surfaces which are formed of a spherical surface, a cylindrical surface or a conical surface on an occlusal surface thereof, and the other of the pair of artificial molar teeth has opposing surfaces which are formed of a flat surface, a spherical surface, a cylindrical surface or a conical surface in point contact or line contact with the adjustment surfaces on an occlusal surface thereof.
