  • Patent number: 11730573
    Abstract: A method including fixing a dental drill template with a fixation pin including a rod and a head attached to the rod. The dental drill template can be fixed by inserting the rod into the drill template or a sleeve provided in the drill template such that a bearing surface of the head bears at least partially on the drill template. The rod has a shape of an essentially circular cylinder and extends from the bearing surface of the head at an essentially right angle. A diameter of the head at the bearing surface is larger than the diameter of the rod.

  • Patent number: 9039415
    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.

  • Patent number: 9023057
    Abstract: An impacting device for inserting, positioning and/or removing an implant and/or performing other impacting applications. The impacting device may have a head having at least one recess. The recess may have a insertion channel and a locking chamber. In one embodiment, the insertion channel and the locking chamber may be connected by an axial channel. The recess may pass through a lateral surface of the head so that the base surface may remain cohesive or unobstructed. A guide means, such as a guide rod, may be positioned though the recess so that the head may be moveable on the guide means and not disengage the guide means. A shaft having a handle may be attached to the head to assist a surgeon in moving the head on the guide means.

  • Patent number: 8851890
    Abstract: Impression cap for a dental implant, with a recess (8) extending in the longitudinal direction between two end areas (4, 6) of the impression cap. The recess is configured in such a way that it can receive a fastening element, which is intended to connect the impression cap to the dental implant via a first of the two end areas (4). The impression cap, at its second end area (6) remote from the first end area, has a connection element that is configured in such a way as to produce a releasable snap-fit connection between the impression cap and the dental implant.
