A structure of the artificial teethridge, the fang and the prosthesis 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 form integral on the top of the artificial teethridge. The artificial teethridge, the fang and prosthesis are an integral structure, whereby the artificial teethridge, the fang and the prosthesis 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. A dental neck form integral between the artificial teethridge and prosthesis, the dental neck being formed in a waisted shape that is narrower at middle section and gradually becomes wider toward to two terminal sections.
