The present invention discloses an abutment of a dental implant consisting of an abutment screw and a shoulder surface. The upper structure of a crown or bridge abutment, i.e., the abutment screw is made of titanium alloy, and surface-treated in brown color by an anodizing process, and the connecting structure thereof, i.e., the shoulder surface is made of ceramic material containing zirconia of a white color, thereby providing an adequate mechanical strength, while maintaining the natural color of human teeth and light permeability. Further, the present invention discloses a method of aesthetically surface-treating the abutment screw of a dental implant abutment by using the anodizing process, and a method of fabricating the shoulder surface of a dental implant abutment.
