Abstract: A setting tool for nails comprises a hollow cylindrical grip sleeve open at both ends with a first hollow section connected by a through-opening to a second hollow section, a ram being disposed in the first hollow section and having one end with an arrangement for releasably holding a nail extending from a first end of the grip sleeve, a pin being disposed in the first hollow section between the ram and the through-opening, the pin having a first segment connected by a centering section to a second segment which extends through the through-opening, a coupling member having a blind bore of the diameter of the second segment being disposed in the second hollow section, with the blind bore facing the pin and being urged toward the pin by a compression spring disposed in the second hollow section entrapped between the coupling member and an adjustable device.

Abstract: Enossal tooth implant for firmly seating dental prostheses has an essentiy cylindrical base member, which is introducible into a bore introduced in a jaw bone and has a blind bore open toward its coronal end, a spacer sleeve which has an inside bore, is emplaceable on a coronal face edge of the base member and has an arrangement for a twist-resistant fastening to the base member, and has a fastening head for a dental prosthesis and an implant post which is introducible through the inside bore into the blind bore and connectable to the base member.

Abstract: An enossal single tooth implant for a fixed dental prosthesis includes an essentially cylindrical base member which is insertable into a bore introduced into a jaw bone and which has a blind bore open toward one coronal end to form a face edge, a spacer sleeve attached in an anti-twist fashion to the face edge of the member, an implant post directly or indirectly introduced into the blind bore of the base member and at least partially penetrating the spacer sleeve. The spacer sleeve has a circumferential surface which forms part of a fastening head for the dental prosthesis and has an annular joining shoulder for engaging an edge of the prosthesis that has a peripherally varying spacing from the face edge of the base member to allow for adaptation to the anatomical conditions.

Abstract: An enossal single tooth implant for a tightly fitting dental prosthesis crises a substantially cylindrical base body insertable in a bore made in a jaw bone and having a blind bore extending inward from one end for receiving a plug portion of a spacing sleeve with the spacing sleeve and the blind bore having an arrangement of coacting elements to prevent a twisting therebetween. The coacting elements include at least one axially extending groove and at least one axially extending projection with each groove being located immediately adjacent the outer edge of the base body and with each projection being adjacent a shoulder of the spacing sleeve which shoulder is engaged on the outer edge of the base body when the sleeve is mounted thereon. In addition to the positive elements, the plug portion has a cylindrical guiding portion followed by a cylindrical centering portion of a smaller diameter.

Abstract: Cover device for temporarily covering bone voids, particularly a recess, which are filled with ossiferous material such as hydroxyl apatite granules, in the proper bone tissue of the body, comprises a perforated reinforcement element for covering the void in essentially a shape-stable fashion that is composed of relatively stiff but flexible material such as a supporting grid of metal or the like, and a single-layer or multi-layer cover membrane carried by the reinforcement element, and at least one of the layers of the cover membrane is applied as a solution film onto the reinforcing element after the use-specific shaping of the element as well as a method for the production of the element.

Abstract: A membrane for temporarily covering a recess in the endogenic bone tissue filled with an osteogenic material, such as hydroxyapatite granules, as is needed following reconstruction of bones in plastic surgery or operations on the jaw, is composed of resorbable membrane material.

Abstract: Supporting grid for the mechanical support of a cover membrane, which membrane covers a bone void filled with a bone replacement material such as hydroxyl apatite granules, particularly a recess in the proper bone tissue of the body, characterized in that the supporting grid is bendable around at least one axis predetermined by the fashioning of the supporting grid.

Abstract: A bone growth promoting composition, comprising a content of at least one substance from the group consisting of the growth factors FGF, TGF-.beta., IGF-II, PDGF and biologically active mutants and fragments thereof and bone extracts with the corresponding activity as well as a bone extract with BMP activity. In combination with an appropriate application material, the use of the composition in the preparation of implant material is also described.

Abstract: An enossal implant includes a base member, a one-piece spacer member and tening head which has a skeleton structure composed of metal and plastic material. The spacer sleeve has a blind bore with threads in the fastening head portion for receiving a threaded implant post. The skeleton structure has cavities in a metal body filled with an elastic plastic material to enable the spacer sleeve to be compressed in an axial direction and also to bend in response to bending stresses.

Abstract: A post-surgery orthopedic covering for a recess in endogenic bone tissue filled with an osteogenic material, such as hydroxyapatite granules, has a covering membrane with a stiffening layer which can be integrated with the covering membrane, or provided as a separate stiffening element.

Abstract: An enossal single-tooth implant for tightly-fitting dentures, characterized y a substantially cylindrical basic body inserted in a bore made in the jawbone and having a blind bore opening to an outer end, a spacing sleeve engageable on the outer end of the basic body, an implant post insertable in the blind bore of the basic body and connectible in a rotation-prevented manner to the basic body, a joining device for fixing the spacing sleeve to the basic body and a fixing head for the denture joined to the implant post. The implant includes that the fixing head and the joining device are constructed as a one-piece bell-shaped hood having a tapering skirt, which concentrically surrounds the implant post and whose skirt engages over the joint area between an outer circumference of the basic body and the spacing sleeve, with the tapering skirt area being constructed in such a way that it gently extends over a cylindrical circumferential wall of the basic body.

Abstract: An implant has an implant member which is implantable in a bone material and has an axial threaded bore at one end which receives a threaded element which may be an implant post, an implant extension or a post for attachment by means of a screw connection. The threaded element has a head with a diameter greater than an outer diameter of the implant member adjacent the one end and the head has a pressing surface extending substantially at right angles to the axis of the implant member and beyond the outer diameter of the implant member. The head also has a circular recess between the pressing surface and the outer threads of the threaded element, which recess will receive an edge of the one end of the implant member when the threaded element is received in the threaded bore to prevent body tissue from growing into any slit or crevice between the implant member and the threaded element.

Abstract: The invention relates to a member provided with an external screw thread, which at least in the end portion of the screw thread is provided with at least one plastic part for at least partially covering the same and/or at least partially replacing the same.
