    Abstract: A dental implant system having a dental implant, an abutment and a threaded screw is provided. The abutment has a guiding and lock structure and the dental implant has a complementary guiding and lock structure, for associating the abutment to the dental implant, with each guiding and lock structure having an anti-rotational structure. Threaded engagement of the threaded screw to a threaded section of the dental implant is not possible, when the anti-rotational structure of the abutment is held in an intermediate position on the anti-rotational structure of the dental implant, which intermediate position is a position where the longitudinal axes of the guiding and lock structures of the abutment and of the dental implant are coaxial with one another.

    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: A dental implant with an implant extension that are formed along a longitudinal axis. The dental implant has apical and coronal ends and a section for receiving and securing an abutment. The implant extension is formed in one piece with the implant and extends away from an end face of the apical end along the longitudinal axis. The implant extension has a first section along the longitudinal axis with an annular constriction directly connected to the apical end face of the implant. The implant breaks off from the implant extension at the constriction. The second section and splined shaft section are arranged along the longitudinal axis following the first section so as to be further away from the implant than the first section. The second section includes an outer annular groove that is designed to be clamped in the direction of the longitudinal axis to hold the implant extension.
