A dental abutment is provided with an axial through hole and is fastened at a lower segment thereof with an implant in conjunction with a cement which is infected into a threaded hole of the implant. An excess amount of the cement is forced out via the axial through hole of the abutment such that the cement is deposited on a flat top of the abutment to facilitate the removing of the cement residue and to minimize the likelihood of a gums inflammation which may be resulted from an incomplete removal of the cement residue.
