Abstract: The present invention refers to a shaft of a dental tool comprising a distal end region, a cylindrical shaft region adjoining the distal end region, and a proximal end region which lies opposite the distal end region and which is provided with a polygonal profile that tapers conically in the direction of the distal end region and adjoins a tool part.

Abstract: An enossal single tooth implant for a fixed dental prosthesis includes an essentially cylindrical base body which can be inserted into a boring in a jaw bone, an abutment which can be inserted in the annular recess of the base body and has a boring for receiving a retaining screw and with a securing head for the dental prosthesis and a retaining screw which can be inserted into the blind hole of the base body and traverses the abutment.

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: 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: 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: A fastening nail for fixing a cover membrane to a bone void which surrounds the bone of the body itself and is filled with an ossiferous material has a nail head with a larger diameter which enables receiving pressure of an impact tool for inserting a nail shaft with a smaller diameter into the bone. The nail shaft has essentially a cylindrical holding part extending to a conical tapering point part adjacent one end and is provided with a transition region between the holding part and point part having an annular shoulder with an enlarged diameter which has a conical surface merging obliquely with the generated surface of the point part in a direction toward the point of the nail and an annular surface extending substantially perpendicular relative to the holding axis of the nail. To insert the nail, the setting tool is elongated and has resilient jaws for gripping the nail and is used in combination with an auxiliary tool which has a foot with downwardly extending points for holding the membrane on the bone.
