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.
