CONSTITUTION: An implant which adopts a locking taper coupling method comprises: an abutment(20) combined with an artificial tooth root; a crown(10) combined with the top of the abutment in the locking taper mode; and an implant(30) combined with the crown. In the abutment, an annular protrusion with the locking taper side is formed on the outer circumference and a groove with the locking taper side is formed on the center. In the crown, a rim protrusion with the locking taper side is formed at the inside to surround the annular protrusion of the abutment.
