  • Publication number: 20190282340
    Abstract: The present invention provides a handling tool (60, 160) for a dental component (20, 40) having a distal end (69, 169), a proximal end (68, 168) and a longitudinal axis L. Further, the handling tool (60, 160) comprises a grip (63, 163) at the proximal end, a shaft (65, 165) located distally of the grip (63, 163) with an engagement section (61, 161) for engaging an engagement feature (32, 132) of a fastening element (30, 130) and a retaining section (62, 162) for retaining the dental component (20, 40) to be fastened by the fastening element (30, 130). The retaining section of the handling tool is configured to allow for a rotation relative to the dental component.

  • Patent number: 10350033
    Abstract: A dental implant for insertion in the jaw bone of a patient is provided. The dental implant has an elongated body having a longitudinal axis and a coronal end, an interior bore extending longitudinally from the coronal end, and a plurality of longitudinally extending anti-rotation structures formed at the inner circumference of the interior bore. The anti-rotation structures have a first set of anti-rotation structures constituting a first anti-rotation feature and a second set of anti-rotation structures constituting a second anti-rotation feature which is independent from the first anti-rotation feature. The anti-rotation structures of the first set and the anti-rotation structures of the second set extend in part over a common length along the longitudinal axis.

  • Publication number: 20190133774
    Abstract: The invention relates to a tibial component (1) of a knee endoprosthesis for anchoring on the proximal tibia, comprising a tibial plateau (2), a tibial shaft (3) on the underside of the tibial plateau (2) facing the tibia, and having a liner (4) for receiving and supporting the lateral condyle surface of a femoral part. To allow different heights and shapes of the liner to be provided medially and laterally, and to ensure that just one individual liner can be exchanged in the event of revision and, for this purpose, a minimally invasive intervention (operation) is sufficient, it is suggested according to the invention that the tibial component (1) has one liner or preferably two liners (4a, 4b) embodied as individual parts, which liner or liners is/are exchangeably anchored on the tibial component (1).

  • Patent number: 9364275
    Abstract: A system and method for pressing fragments of a fracture against each other includes a compression device comprising a hollow shaft. The system has an inner engagement portion for engaging an outer feature of a screw head arranged at a distal end of the shaft. The system has a supporting element with a contact surface adapted to abut on one of the fragments, and a joint is provided between the supporting element and the hollow shaft. The joint is formed so as to allow a rotation of the shaft about a longitudinal axis thereof relative to the supporting element. Additionally, the joint is formed to allow a pivot movement of the supporting element relative to the shaft.

  • 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).
