    Abstract: Abutment for a dental implant (50), with an apical end (4) and with a coronal end (6) arranged opposite the apical end in the longitudinal direction. In the area of the apical end (4), the abutment has an insert portion (8) which is designed to be received by an opening of the dental implant and which has an anti-rotation segment (10) with at least one anti-rotation element (27) which is designed to cooperate with a corresponding mating anti-rotation element (53) of the dental implant (50). The anti-rotation element (27) has a groove (18′, 18″) which, from the edge of the anti-rotation segment (10) directed toward the apical end (4), extends in the coronal longitudinal direction along a groove portion (14) with a substantially constant groove width. The groove (18′, 18″) is continuously widened in a transition portion (20) adjoining the groove portion (14), in order to merge into a bevel (24′, 24″) in a bevel portion (22) adjoining the transition portion (20).

    Abstract: An inlay for connection to a dental implant, including implant connection geometry, for connecting the inlay to the implant and, coronal of the implant connection geometry, a post portion extending along a longitudinal axis, the post portion having a circular symmetric external surface and including at least one protrusion extending radially beyond said external surface, wherein the post portion further includes longitudinally extending grooves which extend radially inward of said external surface and are located directly adjacent to and on either side of the at least one protrusion such that the proximal end of said at least one protrusion is located radially inward of said external surface. The inlay is used in combination with an overlay including an accommodation cavity for housing the post portion of the inlay, the accommodation cavity having a circular symmetric cavity wall and at least one groove dimensioned such that the one or more protrusion of the inlay can be housed in the one or more groove of the overlay in order to inhibit relative rotation between the components.

    Abstract: The present invention relates to a dental drill (10) formed of titanium or a titanium alloy having a hardness greater than pure titanium, said drill extending along a central axis (A) from a proximal end (14) to a distal end (16). The drill comprises a shank (12) arranged in a proximal end region of the drill (10) and extending along the central axis (A), a flute portion (20) arranged distally to and running coaxially with the shank (12), said flute portion (20) comprising two or more flutes (22a, 22b, 22c) extending along the flute portion (20) and being interposed by lands (24a, 24b, 24c), the flute portion further comprising a central solid web and a drill tip (26) directly adjoining the distal end (28) of the flute portion (20) and comprising two or more flanks (25a, 25b, 25c) which taper radially inwardly from the distal end of each land in the distal direction toward the central axis (A), each flank (25a, 25b, 25c) comprising a cutting edge (30a, 30b, 30c). According to the invention, at the distal end of the drill point (26) at least one groove (32, 33a, 33c) is formed in the web such that the distal most end (36a, 36b, 37b, 37c) of at least one of the flanks (25a, 25b, 25c) is located radially remote from the central axis (A).
