A structure of the artificial teethridge and fang includes an artificial teethridge which has an arched top and an arched bottom, wherein the top and the bottom of the artificial teethridge are curved toward the same direction. The thickness of the artificial teethridge is relatively thicker at central part and gradually becomes thinner toward two lateral sides. A fang is installed on the top and the fang has a narrower fang top and a wider fang bottom, whereby the artificial teethridge and the fang form a mechanical conduction structure. The bottom surface of the artificial teethridge has a complementary structure which can be tightly matched and fixed on each point of the top surface of the alveolar bone without any gap, whereby the bottom of the artificial teethridge further includes a fastening fixture.
