  • Patent number: 10149743
    Abstract: The instrument (10) for handling a dental part (50), for example, a male part, extends in a longitudinal axis (11) between a handling end (10c) and a connecting end (10a) for connection to the dental part (50). The connecting end (10a) has a receiving opening for receiving the head (51) of the dental part (50), which is laterally open, so that the connecting end (10a) and the dental part (50) can be connected by displacing them relative to one another transversely to the longitudinal axis (11). The male part (50) includes a head end having at least one protrusion, (53a) with which a stop (17b) that is formed on the instrument (10) can be contacted for transferring a torque generated on the instrument.

  • Patent number: 9968425
    Abstract: The female part for forming a releasable connection to a male part (50) that is configured to be fastened in a mouth includes a housing (20), which is configured to be fastened to a dental prosthesis, an insert (1), which is insertable into the housing and rotatable with respect to the housing and in which a portion (51) of the male part can be accommodated, and an adjusting mechanism that is formed in the housing and on the insert and that cause a change in the diameter of the insert when the insert is rotated with respect to the housing. At least one protrusion (5b, 5c) and at least one recess are provided to form the adjusting mechanism. The female part has a locking mechanism, which is formed on the housing and in the insert for defining discretely arranged locking positions, wherein the insert is compressed more in at least one locking position than in at least one other locking position.

  • Patent number: 8562345
    Abstract: The device for fastening a dental prosthesis includes a bar patrix (20) and a connecting part (10), which can be attached to the dental prosthesis and has a recess into which the bar patrix can be inserted and which is surrounded by two side walls (11, 12) connected via a ceiling element (13). The side walls (11, 12) and the ceiling element (13) are shaped such that the dental prosthesis, when it is placed on the bar patrix (20) via the connecting part (10) attached thereon, rests on the bar patrix via a first (11), a second (12) and a third support location (13c), wherein in each case a free space (14a, 14b) is present between the first and third support locations and the second and third support locations.

  • Publication number: 20100209874
    Abstract: The arrangement for forming a bar construction, to which a prosthesis can be fastened, may comprise: a first connecting element with a first end which has a through-opening through which an end of a fixation screw can be passed in order to fasten the first connecting element in a specific angular position in relation to an implant, and a second end which is connectable with a bar, and a second connecting element, which is connectable by a releasable connection to the first connecting element, and securing means for counteracting a separation of the two connecting elements from each other when these are connected and moved. The two connecting elements may each comprise an end that has a substantially spherical inner face and a substantially spherical outer face. The head of a fixation screw may have a first substantially spherical outer face and a second substantially conical outer face.
