<p>PURPOSE: A connecting screw for a dental implant is provided to allow a rotary tool to be introduced and a connecting screw to be tightened, even if a longitudinal axis of a bore in an abutment or a tooth crown and a longitudinal axis of an inner thread of the dental implant are arranged at an angle, in particular at an acute angle, to one another or if the bore is angled. CONSTITUTION: A connecting screw (22) for a dental implant (18) comprises a shaft portion (32) having a lower screw end and a head portion (34) having an upper screw end located opposite the lower screw end. The shaft portion and the head portion are arranged along a central longitudinal axis (C) of the connecting screw. The shaft portion has an outer thread for connection to the dental implant. The head portion has a blind-bore-shaped recess (36), which is open toward the upper screw end and in which an engagement unit for a rotary tool (24) is integrally formed. The blind-bore-shaped recess expands radially below the engagement unit toward the lower screw end and forms an undercut.</p> |
