The present invention relates to an abutment for an implant, and more specifically, to an abutment for an implant capable of improving sealing with a fixture through the formation of a groove in a contact portion. The abutment for an implant according to one aspect of the prevent invention comprises a screw portion, a contact portion, and a head portion. The thread of a screw is formed in the screw portion so as to allow the abutment to be inserted into a fixture to be coupled by a screw. The contact portion is tapered at the upper portion of the screw portion so as to be inserted into a tape portion of the fixture to come in contact with the same. The head portion is formed at the upper portion of the contact portion to enable coupling of prosthesis. Particularly, in this case, the contact portion has a plurality of grooves, which are formed along the circumference direction in a region in contact with the tape portion of the fixture, to reinforce adhesion with the tape portion of the fixture. According to the present invention, the local area of the contact portion is modified into grooves in case of fastening with the fixture by providing the abutment having grooves formed in the contact portion. Therefore, sealing effects can be improved by increasing adhesion between the abutment and the fixture.
