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.

Abstract: The arrangement for fastening a dental prosthesis to a male bar including a female housing that is connectable to the dental prosthesis and at least two inserts that are insertable into the female housing and extend over the male bar when the female housing is attached to the latter. The arrangement allows a simpler adjustment of the retention force that retains the female housing on the male bar.

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.

Abstract: The extracoronal attachment comprises a female part (65), which is to be connected to the dental prosthesis, and a male part, which can be fastened to a natural tooth or implant and which has an approximal part (51). The approximal part has, on each of two opposite longitudinal sides, at least one longitudinal groove (20) or longitudinal rib inside of which a corresponding longitudinal rib (30) or longitudinal groove of the female part enters whereby establishing a positive connection, and has at least one occlusally facing bearing surface, on which the female part rests with a supporting surface. The female part comprises a housing, with which the longitudinal ribs (30) or longitudinal grooves of the female part and the supporting surface are provided as a single piece.
