The blind hole comprises a retaining segment (4), the inner wall of which is partially or entirely formed by a concave, cylindrical retaining surface (40) with an elliptical or oval-shaped base for retaining by embedding an essentially cylindrical portion (101) of the interface (100) or of the attachment.

The invention relates to a superstructure support (20) as part of a prosthetic tooth replacement (1) between an implant body (10) and a superstructure, comprising a hollow implant post (23), a hollow implant pin (50), and an implant flange (31) lying therebetween. The cavity zones (67, 62) of the implant post (23) and of the implant pin (50) transition into each other. The cavity zones have respective center lines (69, 63), which include an angle of 60 to 86 angular degrees. The cavity zone (62) of the implant pin (50) has a screw head seat surface (65) that widens toward the implant flange. At least some areas of the implant flange form a supporting enveloping surface (37), which is oriented toward the implant post (23) and the outer edge (33) of which spans a reference plane (38), which is perpendicularly intersected by the center line (69) of the post-side cavity zone (67). The center lines of the implant post (23) and of the implant pin (50) intersect or cross below the reference plane (38). By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that a secure and lasting screwed connection to the implant body is ensured.

A dental implant system including an implant, a prosthetics component, and a fastener. The implant and the prosthetics component are configured to assume a first taper connection and a second taper connection with one another. The implant has a male connection portion of the first taper connection. The prosthetics component is placed upon the implant and when the prosthetics component is not fastened to the implant by the fastener, a tolerance region is formed between the implant and the prosthetics component. The tolerance region is configured such that on fastening with the fastener, mating connection portions of the taper connections can be pushed further into one another.

The present invention relates to a dental implant set having a fixture for insertion into a bore hole arranged in bone tissue having first indexing means, a dental component having second indexing means and being adaptable to the fixture in an engaged position where the first and second indexing means mate and in an intermediate position where the dental component and the fixture are in contact with each other but the first and the second indexing means do not mate, and a fixation screw being adapted for fixating the dental component to the fixture. The present invention also relates to a method for attaching a dental component to a dental fixture.

A screw-shaped anchoring fixture for anchoring a prosthesis in the skull bone. The anchoring fixture comprises a main body configured to be implanted into the bone and a flange configured to function as a stop to prevent the main body from completely penetrating through the bone. The main body comprises a distal tapered apical portion, a first portion, and a second portion. The inner diameter of the second portion is greater than the inner diameter of the first portion. The method for inserting the anchoring fixture includes providing the anchoring fixture, drilling a hole, and inserting the anchoring fixture into the hole until the flange contacts the skull bone, wherein the hole has a diameter that is greater than the inner diameter of the first portion and less than the outer diameter of the second portion.

A dental implant including an implant body having a top surface, and at least one non-annular cutaway portion longitudinally extending downwardly from the top surface along one side of the body and outwardly to the periphery, and a method for making the implant. The implant body preferably includes a body portion and a head portion integrally formed with the body portion, the body portion has a periphery and the head portion has a non-circular periphery, and the periphery of the head portion is smaller than the periphery of the body portion.

A two part modelling aid (1, 100) for connection to a dental implant component (200), the modelling aid comprising a hollow base part (10, 110) comprising an open apical end (14, 114), an open coronal end (16, 116) and a tubular side wall (12, 112) extending from the apical to coronal end along a linear longitudinal axis (L.sub.B), the side wall having an interior and an exterior surface, one of said surfaces comprising an anti-rotation section (18, 118) having a non-circular symmetric cross-section in a plane perpendicular to the longitudinal axis, and a hollow angled part (30, 30) comprising an open apical end (34, 134), an open coronal end (36, 136) and a tubular side wall (32, 132) extending between the apical end and coronal end and having an interior and exterior surface, the tubular side wall forming an apical portion (35, 135) of the angled part extending along a first linear axis (L.sub.1), and a coronal portion (37, 137) of the angled part extending along a second axis, the second axis being non-coaxial to the first axis such that the tubular sidewall creates a non-linear channel (38, 138), the apical portion being sized and shaped to form a friction fit with the base part, wherein, when the base part is connected to the angled part, a closed channel (60, 160) is formed extending from the apical end of the base part to the coronal end of the angled part, the first axis of the apical portion of the angled part being coaxial to the longitudinal axis of the base part and the anti-rotation section of the base part being exposed on a surface of the base part.

The invention relates to a dental implant for mounting in the jaw bone, comprising a base portion, an abutment and a connecting screw, the post of said connecting screw having a stepped design, wherein the diameter of the bottom part thereof before the beginning of the thread of the post does not exceed the inner diameter of the bearing thread of the abutment, and the distance from the head of the screw to the top end thereof is smaller than the axial distance from the head of the screw to the bearing thread of the abutment by 0.1-1 mm (optimally by 0.2-0.3 mm). According to claim 1, comprising the base portion of the implant, the abutment, and auxiliary components, the latter comprising a set of connecting screws having a screw thread pitch appropriate for the abutment sizes for prosthesis implantation in patients with a high, medium and low gum height.

An implant system including a dental implant and an abutment produced from a ceramic material, wherein the abutment includes a first anti-rotation element with multiple grooves and the dental implant includes a second anti-rotation element, which is complementary thereto, with multiple ribs, wherein the grooves are open toward a proximal end of the abutment.

A dental-implant system having a first implant part provided for being inserted into a jawbone and having a second implant part associated therewith, provided for fixing a dental prosthetic piece, the implant parts being mechanically connectable to each other via a connection pin which is formed onto one of the implant parts and which can be pushed into a receiving channel provided in the other implant part, and the cross-section of the connection pin and the cross-section of the receiving channel associated therewith each presenting in an indexing area a number of main directions in which the radius takes in each case a relative maximum value, shall offer an even increased mechanic load-carrying ability and thus a particularly long service life when used in the patient's mouth. For this purpose, according to the invention, the outer cross-section of the implant part including the receiving channel is configured such that its radius also takes a relative maximum value within a tolerance range of each of the main directions.
