The present invention relates to an abutment of an implant system. It is a primary object of the present invention an abutment of an implant system capable of achieving an escape groove of air compressed in an assembling hole in such a manner that a circular rim groove is formed at a post part of an abutment. In addition, it is capable of enhancing a surface contacting state in such a manner that a certain flexibility is provided at an upper side and a lower side of a post part. An easier operation work can be achieved in such a manner that it is easy to hold using a tool or a jig when an abutment is inserted into and is pulled out from a fixture. To achieve the above objects, in an implant system that includes a fixture having a taper assembling hole at an upper surface, an abutment having a taper post part so that it is inserted into the assembling hole of the fixture, and a restoration assembled to an upper side of the abutment, there is provided an abutment of an implant system comprising at least one circular rim groove formed at an outer surface of a lower side of an intermediate portion wherein the post part is assembled into the assembling hole.
