A prosthesis fastening protrusion protrudes outward from an outer surface of an upper portion thereof on which a prosthesis is mounted. The diameter of the prosthesis fastening protrusion being greater than the diameter of a portion located directly therebelow. Indentations divide the upper portion of the abutment into a plurality of sections. The indentations continuously extend downward a predetermined length from a top end surface of the abutment. A predetermined lengthwise portion of each of the indentations has a spiral or oblique shape.
