Pure compressed diamond (PCD), grown in a laboratory, is laser-shaped into dental implants with high tensile strength, high compressive strength, high thermal conductivity, and which are harder than any other substance on earth. PCD is harder than ceramic zirconia and harder than titanium. Because PCD is pure carbon, it is also 100% compatible with carbon-based living tissue. Unlike titanium, it does not provoke an immune response. PCD implants readily integrate into human jawbone. This drastically reduces post-surgery bone loss.

A dental implant (1), in particular for insertion into bone tissue of a patient, comprising: a core body (2) having an apical end (4), a coronal end (6), and an outer surface (8) extending along a longitudinal direction between said apical end (4) and said coronal end (6); and at least one thread (12) located on at least a threaded portion of said outer surface (8), should have superior properties regarding primary and secondary stability. According to the invention this is achieved in that the core body (2) comprises a core shaped zone (22), preferably next to said coronal end (6), in which core shaped zone (22) the cross-section of said core body (2) has a number of main directions in which the radius measuring the distance between the center (50) of the cross section and its outer contour takes a relative maximum value and thus a higher value than in neighboring orientations, a core circular zone (20), preferably next to said apical end (4), in which core circular zone (20) the cross-section of said core body (2) is basically circularly shaped, and, as seen in said longitudinal direction, a transition zone (26) positioned between said core shaped zone (22) and said core circular zone (20), in which transition zone (26) the geometry of the cross-section of said core body (2), as a function of a parameter characteristic for a coordinate in said longitudinal direction, changes continuously from a basically circular shape next to said core circular zone (20) to a shape in which the cross-section of said core body (2) corresponds to the shape of the cross section in said core shaped zone (32). The invention further relates to an insertion tool (200) for inserting a dental implant (1, 201, 401) into bone tissue of a patient. Moreover, the invention relates to a combination of such a dental implant (1, 201, 401) and such an insertion tool (200).

A dental implant assembly containing an integrally-formed universal abutment which has a top section, a bottom section integrally joined to the top section, and a passageway extending through these sections. The passageway is formed by different size bores, initially a larger size than decrease in size. The top section of the abutment has a cross-sectional shape substantially like a polygon; the shape is formed by alternating linear and arcuate walls joining to a bottom section having a cross-sectional shape substantially like a polygon.

An abutment for use with a dental implant. The abutment includes a connecting pin configured to be introduced into an associated receiving channel of the dental implant. The connecting pin includes a screw channel for a connecting screw for connecting the abutment to the dental implant. An inner diameter of the screw channel over its entire length up to an opening on an end face is at least as large as the diameter of a screw head of the connecting screw, and a plastically deformed retaining element is provided in order to support the connecting screw.

This invention provides a measure that makes it possible to prevent more effectively, in comparison with the prior art, the invasion of germs from the gap between a dental prosthesis and the gingiva when the dental prosthesis is used in an oral cavity as well as the infection and inflammation associated therewith.

There is a dental prosthesis or a component thereof, characterized in that: the dental prosthesis or the component thereof has hydroxyapatite fine particles on a surface of the dental prosthesis or the component thereof; the hydroxyapatite fine particles are sintered bodies; and the hydroxyapatite fine particles have a mean particle size of 10 to 1,000 nm.
