The present invention relates to a dental implant, and more particularly, to a dental implant including a fixture 10, an abutment 30 coupled to an upper end of the fixture 10, and an abutment fixing screw 40 coupling the abutment 30 to the fixture 10. The fixture 10 is molded of ceramic and includes a screw part 13 disposed on an outer circumferential surface and a screw hole 14, to which the abutment fixing screw 40 is coupled, disposed in a central axis direction. A helical coil 20 is disposed between the screw hole 14 of the fixture 10 and the abutment fixing screw 40 to couple an outer portion 21a of the helical coil 20 to a screw valley 14a of the screw hole 14 of the ceramic fixture 10 and an inner portion 21b to a valley 41a of the screw part 41 of the abutment fixing screw 40 in a screw coupling manner.
