A self-retaining screw assembly comprising a dental secondary component and a screw. The secondary component comprises a through passage having an apical and a coronal open end, and a screw seat located between said apical and coronal ends. The screw comprises a screw rod and a screw head, the screw head being dimensioned to abut against the screw seat and the screw rod being dimensioned to pass unhindered through the through passage such that the apical end of the rod can protrude from the apical end of the through passage. The through passage further comprises, coronal of the screw seat, a first section and, directly coronal of the first section a second section having a narrower diameter than the first section, such that the second section forms a restriction in the through passage. The screw head comprises a radially outwardly extending retaining element.
