<p>A method of manufacturing an abutment of an artificial tooth, which includes an implant fixture installed in a jaw bone and a crown defining a contour thereof. The abutment is fixed to the implant fixture to connect the implant fixture to the crown. A three-dimensional image of an oral cavity of a patient is generated on a computer by 3D scanning of a dental plate of plaster. A virtual tooth is designed using the image of the oral cavity, in consideration of a row of teeth in a region from which a tooth is missing, the height of adjacent teeth and alignment with an upper or lower tooth. The shape of the abutment is designed according to the shape of the designed virtual tooth. Data on the designed abutment is transmitted to a precision machine. The designed abutment is cut using the precision machine to have a one body structure.</p> |
