Abstract
Connecting screw (22) for a dental implant (18) can be screwed securely by means of a commercially available rotary tool (24), even if the central longitudinal axis C of the connecting screw (22) and the longitudinal axis D of the rotary tool (24) are arranged at an acute angle to one another. For this purpose, the connecting screw (22) has a shaft portion (32) having an outer thread (48) for connection to the dental implant (18), and a head portion (34) having a blind-bore-shaped recess (36), which is open toward the upper screw end (46) and in which an engagement means (50) for the rotary tool (24) is formed integrally.
