  • Patent number: 9119688
    Abstract: A holding device for retaining and transporting a dental implant, particularly a dental implant stored in an ampule having preserving fluid, is provided. The holding device has a securing section, which has a force transmission element for rotationally securing the dental implant and an attachment element having one or more resilient arms formed integrally with and distally of the force transmission element, for longitudinally retaining the dental implant. The resilient arms do not extend beyond the radial perimeter of the force transmission element. The resilient arms can be transformed between a first operative configuration and a second compressed configuration under forces during operation, to allow a radially enlarged end of the arms to releasably engage an undercut of the dental implant.

  • Patent number: 8864494
    Abstract: A housing (35) for an implant (25), a holding piece (1) to connect the implant (25) to the housing (35), and an insertion tool (20) for inserting the implant (25) into an implant site. The holding piece (1) includes at least one resilient element (45) for detachably connecting to the implant (25) with a first retentive force and a tool retention means to connect to the insertion tool (20) with a second retentive force which is greater than the first retentive force. In between the two ends the holding piece (1) features a housing connection segment (30) for connecting the holding piece (1) to the housing (35). On a distal end the insertion tool (20) comprises torque transmission means, which transmit torque directly to the holding piece (1) and/or to the implant (25).

  • Publication number: 20100196855
    Abstract: Impression post for a dental implant, having a sleeve-shaped impression cap (4) with a coupling section (16) configured to be connected to the dental implant (20), and a substantially cylindrical recess (6) extending in the longitudinal direction of the impression cap (4) and an attachment element (8) engaging through the recess (6) for attaching the impression cap (4) on the dental implant (20). The impression cap (4) has an inner sleeve (10) and an outer sleeve (12) radially surrounding said inner sleeve on the outside, which outer sleeve is detachably connected to the inner sleeve (10), and the coupling section (16) is at least partly an element of the inner sleeve (10).

  • Publication number: 20070099150
    Abstract: Dental drill device (10) comprises a drill (12) with a stop element (28). In various embodiments, at one end, the drill (12) has a cutting part (14) with a free drill end (16) and, at the other end, it has a shank part (18). Arranged on the shank part (18) there is a holder portion (26) with several fastening recesses (30) spaced apart from one another in the axial direction (A), each fastening recess (30) being limited, in the direction of an exposed receiving end area (20) of the shank part (18), by an abutment surface (34) which is at right angles to the axial direction (A) of the drill (12). A stop element with a drill abutment (36) is fitted onto the holder portion (26) and has an engagement element (58). The engagement element (58) has a counter-abutment surface (35) which cooperates in a form fit with the abutment surface (32).
