摘要:
Combination of a screw (160; 160 ') for a dental application and a screwdriver to drive the screw for securing a dental component in a dental implant, the screw having a coronal end and an apical end and comprising: a hole that is extends from the coronal end of the screw along a part of the screw towards the apical end of the screw, a first number of equidistant recesses (350) arranged circumferentially around the inner surface of the hole, each recess (350) extending a section from the coronal end of the hole towards the apical end of the hole, in which the section of each recess (350) is inclined with respect to the longitudinal axis of the screw such that the recess (350) is further from the longitudinal axis of the screw in a point parallel to the coronal end of the hole that at a point below the coronal end of the hole, where each pair of adjacent recesses (350) are c located through a contact surface (320) on the inner surface of the hole, each contact surface (320) extending a section from the coronal end of the hole to the apical end of the screw, and in which each contact surface (320) is inclined, away from the longitudinal axis of the screw, such that the surface is farther from the longitudinal axis of the screw at a point parallel to the coronal end of the hole than at a point below the coronal end of the hole, the screwdriver comprising a head (400) of the screwdriver having an apical end and a coronal end, the head of the screwdriver comprising at least a first and a second part having a polygonal cross-section in a radial plane of the longitudinal axis of the screwdriver, the first part having (450) a substantially rounded cross section in the axial plane of the longitudinal axis of the screwdriver, the second being part (460) connected in an apical direction with respect to the first part, the second part having a substantially triangular shape that narrows towards the apical end of the head (400) of the screwdriver in the axial plane of the longit
