Secondary part, set, dental implant, gingiva former, impression part, dental implant system, and method for producing an implant

A dental implant for insertion into a jawbone, for use with a secondary part for attachment to a dental implant and suitable for receiving an auxiliary part or a tertiary part, wherein the secondary part comprises:

• a secondary-part body with a recess on an inside,
• a secondary-part screw being able to be accommodated within the recess,
• wherein the secondary part has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool, for screwing in the dental implant into a jawbone, if said dental implant is connected to the secondary part,
• wherein at least the secondary-part screw has a self-retaining structure for engaging with the screwing-in tool, and the self-retaining structure is formed by a resilient head, and
• wherein an outside of the secondary-part body is formed in such way that during intended use of the secondary part, the outside of the secondary part conically tapers inwardly, at least in part, at a coronal end region on which the auxiliary part or the tertiary part can be received, such that the secondary-part body has a coronal cone extending partially in the circumferential direction, wherein the angle between the longitudinal axis of the secondary-part body and the conical portion is between 5° and 15°,
• for use with a set comprising the dental implant and the secondary part,
• the dental implant comprising an external thread with a thread root for anchoring the dental implant in the jawbone,
• wherein the thread root has at least one elevation extending from the thread root and being located between two adjacent thread flanks, and wherein at least two cutting grooves are arranged in the area of the external thread, wherein the cutting grooves are formed as twisted cutting grooves, and in that at least one short cutting groove and at least one long cutting groove is provided, wherein the short cutting groove is shorter than the long cutting groove, and
• wherein the short cutting groove extends from the apical end and runs across the apical area, starting from the apical end.
