A combination of a screw (160; 160') for a dental application, and a driver for driving the screw for fastening a dental component to a dental implant, the screw having a coronal end and an apical end and comprising: a bore running from the coronal end of the screw along a portion of the screw towards the apical end of the screw, a first number of equally spaced recesses arranged circumferentially around an inside surface of the bore, each recess running a length from the coronal end of the bore towards the apical end of the bore, wherein the length of each recess is angled relative to the longitudinal axis of the screw such that the recess is further from the longitudinal axis of the screw at a point parallel with the coronal end of the bore than at a point below the coronal end of the bore, wherein each pair of adjacent recesses are connected by a contact surface on the inside surface of the bore, each contact surface running a length from the coronal end of the bore towards the apical end of the screw, and wherein each contact surface is angled away from the longitudinal axis of the screw such that the surface is further from the longitudinal axis of the screw at a point parallel with the coronal end of the bore than at a point below the coronal end of the bore, the driver comprising a driver head having an apical and coronal end, the driver head comprising at least a first and second portion having a polygonal cross-section in a radial plane of the longitudinal axis of the driver, the first portion having a substantially rounded cross-section in the axial plane of the longitudinal axis of the driver, the second portion connected apically relative to the first portion, the second portion having a substantially triangular shape tapered towards the apical end of the driver head in the axial plane of the longitudinal axis of the driver. a bore running from the coronal end of the screw along a portion of the screw towards the apical end of the screw, a first number of equally spaced recesses arranged circumferentially around an inside surface of the bore, each recess running a length from the coronal end of the bore towards the apical end of the bore, wherein the length of each recess is angled relative to the longitudinal axis of the screw such that the recess is further from the longitudinal axis of the screw at a point parallel with the coronal end of the bore than at a point below the coronal end of the bore, wherein each pair of adjacent recesses are connected by a contact surface on the inside surface of the bore, each contact surface running a length from the coronal end of the bore towards the apical end of the screw, and wherein each contact surface is angled away from the longitudinal axis of the screw such that the surface is further from the longitudinal axis of the screw at a point parallel with the coronal end of the bore than at a point below the coronal end of the bore, the driver comprising a driver head having an apical and coronal end, the driver head comprising at least a first and second portion having a polygonal cross-section in a radial plane of the longitudinal axis of the driver, the first portion having a substantially rounded cross-section in the axial plane of the longitudinal axis of the driver, the second portion connected apically relative to the first portion, the second portion having a substantially triangular shape tapered towards the apical end of the driver head in the axial plane of the longitudinal axis of the driver.
