Definitions

  • the invention relates to an endosseous single tooth implant for a fixed dental prosthesis, with an essentially cylindrical base body which can be inserted into a bore made in a jaw bone and which has a blind bore open to its coronal end, one on the coronal front edge of the base body attachable spacer sleeve, an implant post which can be inserted into the blind bore of the base body and which can be connected to the base body and which penetrates an inner bore of the spacer sleeve, a connecting device for securing the spacer sleeve on the base body and secured against rotation, and a fastening head for the dentures .
  • German patent application 195 09 762.9-32 (not previously published) describes the further development of a dental implant according to DE-PS 40 28 855, in which the implant post on its coronal part, which also serves as a retaining screw for the spacer sleeve with respect to the base body End has the fastening head for the fixed dental prosthesis projecting above the spacer sleeve.
  • the dentures are glued to the fastening head, for example, or connected to it by cementing.
  • the invention has for its object to develop the generic single tooth implant in such a way that a screw connection between the denture and the fastening head is made possible without deformation of the wall of the spacer sleeve.
  • the fastening head is formed by a coronal, hollow end region of the spacer sleeve; that the coronal end of the implant post is arranged cervically below the end region; and that in the end area there is an insertion nut provided with a threaded bore running perpendicular to the longitudinal center axis of the spacer sleeve, into which a securing screw for penetrating the denture through the opening in the peripheral wall of the end area can be screwed.
  • the peripheral wall of the spacing sleeve is tapered in the coronal direction in the end region in the manner of a truncated cone.
  • the invention also provides, if necessary, that the implant post can be screwed into an inner bore of the implant with non-rotatably engaging positive locking tongues of the spacer sleeve with complementary positive locking elements of the base body.
  • the insert nut is formed in one piece with a suspension web which is to be placed on the coronal front edge of the peripheral wall of the spacer sleeve.
  • recesses which are opposite one another are provided in the coronal end edge of the spacer sleeve and into which a suspension web formed in one piece with the insertion nut can be inserted. If the suspension web rests in the recesses without play, the insertion nut can be positioned very precisely with respect to the spacer sleeve.
  • the recesses are arranged such that their common center axis runs perpendicular to the axis of symmetry of the opening, which is provided in the peripheral wall of the spacer sleeve.
  • the insert nut preferably has, at its end at least in regions, an outer diameter at its end facing the insert web, which is used to allow a frictional connection between Insert nut and spacer sleeve is slightly larger than the inner diameter of the inner bore of the spacer sleeve in the area corresponding to the insert nut. Again, the insert nut can be securely positioned with respect to the spacer sleeve.
  • the insert nut is provided on its end facing the insertion web with projections which are arranged opposite one another on both sides of the suspension web, the outer contour of the projections defining the regions of larger outside diameter.
  • the invention is based on the surprising finding that it is possible to ensure a perfect screw connection between the denture and the coronal end region of the spacer sleeve designed as a fastening head by inserting an insert nut into the spacer sleeve, which nut is transverse to the longitudinal central axis of the spacer sleeve receives locking screw so that the peripheral wall of the spacer sleeve does not have to absorb any compressive forces.
  • FIG. 1 shows a spacer sleeve of a first embodiment of the endosseous single tooth implant according to the invention in a partial section through the longitudinal central axis;
  • FIG. 2 shows a plan view of the spacer sleeve according to FIG. 1;
  • FIG. 3 shows a spacer sleeve of a second exemplary embodiment in side view, partly in section through the longitudinal central axis; 4 shows a plan view of the spacer sleeve according to FIG. 3;
  • FIG. 5 shows a spacer sleeve of a third exemplary embodiment of the endosseous single tooth implant according to the invention
  • FIG. 6 shows a perspective view of an insertion nut for use in the single tooth implant of FIG. 5;
  • FIG. 7 shows a further longitudinal sectional view of the coronal end of the single tooth implant according to the invention in a plane perpendicular to the sectional plane of FIGS. 1, 3 and 5.
  • the spacer sleeves 14 shown in FIGS. 1, 3 and 5 have, at their lower, cervical end in the drawing, a number of form-locking tongues 16 which connect to a centering collar 18 which, in the coronal direction, connects to the cervical end of the
  • the spacer sleeve adjoining area of the spacer sleeve 14 is offset by a shoulder 20.
  • the spacer sleeve 14 can be inserted in the manner described in German patent application 195 09 762.9-32 (not previously published) into a base body (not shown) which is inserted into the patient's jaw and at its coronal end is provided with the corresponding form-locking elements 16 corresponding form-locking elements 16, so that the spacer sleeve 14 can be connected to the base body in a manner secured against rotation.
  • the spacer sleeve 14 can be securely connected to the corresponding form-locking elements of the base body by means of an implant post designed as a retaining screw, which can be screwed into an inner bore of the base body, by engaging the form-locking tongues 16 with the corresponding form-locking elements of the base body.
  • FIGS. 1, 3 and 5 further show that the spacer sleeve 14 is located coronally following a fastening area 24 in which an inner bore of the cervical and coronally open spacer sleeve 14 has a diameter which corresponds to that of the not shown, has an end region 24 in which an inner bore 26 (FIGS. 1 and 5) has a larger diameter than the inner bore in the region of the fastening region 22. Close to that in the drawing (FIGS. 1 and 5) the end of the fastening area 24 lying at the bottom lies within the inner bore 26 the aforementioned holding head of the implant post, so that the inner bore 26 is thus made coronal in connection with the holding head of the implant post.
  • FIGS. 1, 3 and 5 further show, the end region 24 of the spacer sleeve 14 is provided on the outside with an attachment shoulder 28, as function and purpose in the already mentioned, not previously published German patent application 195 09 672.9-32 im is described, to which reference is made for further explanation.
  • a circumferential wall 30 of the spacer sleeve 14 has a truncated cone shape that tapers coronally.
  • FIG. 1 shows how close to the coronal end edge of the end region 24 of the spacer sleeve 14 in its inner bore 26 is an insert nut 34 which is suspended except for one perpendicular to the longitudinal center axis by means of a suspension web 32 placed on the coronal end edge of the peripheral wall 30 the spacer sleeve 14 extending threaded bore 36 is solid.
  • a locking screw 38 is screwed into the threaded bore 36, which has a screw head 40 and passes through an opening 42 provided in the peripheral wall 30 after the threaded bore 36 has been aligned with the opening 42 before the locking screw 38 is screwed in.
  • the relative positioning of the locking screw 38 and the spacer sleeve 14 is shown particularly clearly in FIG.
  • recesses 44, 46 are provided in the coronal front edge of the spacer sleeve 14 on a common center axis 48, into which the suspension web, not shown in FIG. 3, is to be inserted.
  • the suspension web rests essentially without play in this.
  • flats 50, 52 are formed in the circumferential wall 30 of the spacer sleeve 14, which are used to attach a tool or to align the denture or its framework. These flats 50, 52 also serve to form a cement bolt when the tooth crown is placed on.
  • the endosseous single-tooth implant which is shown in FIG. 5, has an insertion nut 34, which at its end, which faces the suspension web 32, has two protrusions 62, 68 formed integrally with the insertion nut 34, the outer contour of which is so It is dimensioned that the outer diameter of the insert nut 34 is slightly enlarged in the corresponding area compared to the inner diameter of the inner bore 26 of the spacer sleeve 14. In the region of contact of the projections 62, 68 against the inner wall of the inner bore 26, a force directed toward the peripheral wall 30 is therefore exerted by the projections 62, 68, which force holds the insert nut 34 in frictional engagement therewith.
  • the projections 62 and 68 can escape into the spaces 64 and 66, which are formed between the projections 62, 68 and the suspension web 32.
  • the insert nut 34 can thus be positioned in the inner bore 26 such that the threaded bore 36 is aligned with the opening 42 for the locking screw 38. When screwing in the screw 38, there is therefore no fear of the insertion nut 34 moving.
  • FIG. 6 shows such an insert nut 34 in a perspective view.
  • Shaped projections are provided, of which only the projection 62 is shown here, the section length of a projection 62 roughly matching the inside diameter of the threaded bore 36.
  • a free space 64 remains between the projection 62 and the suspension web 32.
  • FIG. 7 shows in a longitudinal sectional view how the insert nut 34 lies in the inner bore 26 of the spacer sleeve.
  • the diameter of the insert nut is not enlarged compared to the inner diameter of the inner bore 26. It can be seen particularly clearly from the illustration in FIG. 7 that the insert web 32 and threaded bore 36 are perpendicular to one another in their axes of symmetry, so that the insert nut 34 can be pre-positioned easily.
  • the spacer sleeve 14, like the implant post and the insertion nut 34, which is formed in one piece with the suspension web 32, are made of a titanium alloy or the like.
