  • Patent number: 10441388
    Abstract: A device is provided for determining the angulation of an abutment for a dental implant. The device includes a conical projection extending from a housing. The conical projection is adapted for insertion into a hole in the dental implant. A rotary body is disposed in the housing and is rotatable among a plurality of different angular positions relative to the conical projection. A rod-shaped indicator is connected to the rotary body. The rotary body can be secured to the housing in one of the angular positions by a locking device. The device may be part of an assembly that includes an indicator device having a receiving opening for accommodating the conical projection and an indicator scale that includes a plurality of marked sectors corresponding to a plurality of predefined abutments, respectively. The location of the rod-shaped indicator relative to the marked sectors indicates the predefined abutment that should be selected.

  • Patent number: 9492248
    Abstract: A dental implant includes a male threading part and an implantation torque increasing part from the tip side. The male threading part includes multiple threading parts that have the same lead but different pitches, with the pitch increasing toward the tip side. The outer diameter of the male threading part is constant or increases toward the implantation torque increasing part. The implantation torque increasing part includes thread crests that have a different lead from the lead of the male threading part or a projecting row that is continuous circumferentially. In cross-section, a contour line connecting tops of the thread crests of the threading part that is adjacent to the implantation torque increasing part is a straight line, and the tops of the thread crests or the top of the projecting row of the implantation torque increasing part are located on an extension line of the contour line.

  • Patent number: 9474589
    Abstract: The invention relates to a multi-part tooth implant with at least a proximal implant part and a distal implant part that are to be connected to each other such that a connection site is obtained when the two implant parts are in the connected state. An annular sealing element is arranged at this connection site and, in the fully assembled state of the tooth implant, is clamped between mutually opposite sealing surfaces, namely a sealing surface of the proximal implant part and a sealing surface of the distal implant part, such that the sealing element has an outer surface portion that forms part of the outer contour of the tooth implant. The two sealing surfaces initially approach each other in a direction oriented outwards from a central longitudinal axis of the tooth implant.
