Provided are related to implant abutments. The implant abutment that is coupled to a fixture that becomes an artificial tooth root by being implanted to an alveolar bone, the implant abutment includes: a main body a first rotating member that is coupled to the main body to be able to rotate with respect to a first rotational axis, includes a first gear portion on an end portion thereof, and includes a male screw portion that is formed on the other end portion thereof to be screw coupled to the fixture and a second rotating member that is coupled to the main body to be able to rotate with respect to a second rotational axis which crosses the first rotational axis, and includes a second gear portion that is formed on the other end portion thereof to form a bevel gear structure by being coupled to the first gear portion. The implant abutment that can readily ensure a space for coupling work of a fixture in an oral cavity of a patient since a coupling tool, such as a hex screwdriver can be readily placed in a horizontal direction which intersects the direction of implanting the fixture.
