  • Patent number: 5667384
    Abstract: The device (1) for forming a dental prosthesis has at least one support (3) with a base (4) which in the use of the device (1) is inserted into a jawbone (13) of a patient or into a jaw model. The support (3) has a conical bearing surface (4n) and also a shoulder (7e) which faces the base (4) and for example is formed by a flank of an annular groove (7d). The device (1) has for the or each support (3) a cap (8) which bears with a conical countersurface (8f) on the conical bearing surface (4n) of the support (44) when the device (1) has been assembled. The cap (8) has a hole (8k) with an internal thread (8m) and with an axis (11) which forms an angle with the axis (10) of the two conical surfaces (4n, 8f). A screw (9) screwed into the hole (8k) engages with a tapering end section (9b) on the outer border (7f) of the shoulder (7e) and thus presses the countersurface (8f) against the bearing surface (4n).

  • Patent number: 5433607
    Abstract: A implant is disclosed particularly for the jawbone, including a diaphragm and a carrier having an elongated column-like central portion and a frame supporting the central portion, as well as spikes for anchoring the carrier into the jawbone. An intermediate piece for fastening the diaphragm at the end of the central portion is also disclosed. The implant facilitates favorable conditions for growth of the bone tissue so that bone material grows into a space covered by the diaphragm due to the solid anchoring of the implant into the jawbone.
