Abstract: A dental implant with an implant extension that are formed along a longitudinal axis. The dental implant has apical and coronal ends and a section for receiving and securing an abutment. The implant extension is formed in one piece with the implant and extends away from an end face of the apical end along the longitudinal axis. The implant extension has a first section along the longitudinal axis with an annular constriction directly connected to the apical end face of the implant. The implant breaks off from the implant extension at the constriction. The second section and splined shaft section are arranged along the longitudinal axis following the first section so as to be further away from the implant than the first section. The second section includes an outer annular groove that is designed to be clamped in the direction of the longitudinal axis to hold the implant extension.

Abstract: A torque wrench, including: a head region with a receiving opening; a bending-resistant shaft region adjoins the head region; a support formed on the shaft region; and an actuating lever including an elastically bendable portion and a handle. The receiving opening receives a screwing instrument and defines an axis of rotation. The actuating lever, in resting position, is spaced apart from the in the circumferential direction to the axis of rotation. If a screwing instrument is inserted into the opening, the actuating lever transmits a torque. The wrench has an indicator region, which the exerted torque can be read as a result of the deflection of the actuating lever. When a reference force is reached, the bending portion comes into contact with the support. When a force is applied, the bending portion can be in the tightening direction and the torque can be read in the region.
