Abstract:
1. A dental implant system comprising a dental implant and a hollow supra-structure element, wherein: (a) the implant comprises a coronal implant region with a coronal circular face side and with a circumferential surface contiguous with the coronal face side, wherein the coronal implant region is designed as a cylinder and the circumferential surface is equipped for promoting osseo-integration, wherein the coronal implant region comprises a cylindrical cavity; (b) the coronal implant region adjoins an apical implant region without a step; (c) the supra-structure element comprises an upper cylindrical portion with a top circular face, an apical/lower sleeve portion and an extension configured to be inserted into the cylindrical cavity of the implant; (d) the supra-structure element is configured for attachment to the coronal face side of the implant and the apical/lower sleeve portion is configured to be placed over the coronal implant region in a cap-like manner such that an edge line of the apical/lower sleeve portion lies against the circumferential surface of the implant and forms a microgap, wherein the edge line comprises an inwardly extending curved surface extending towards the upper cylindrical portion and an outwardly extending curved surface extending away from the upper portion; and (e) a position of the edge line is configured to be adjustable by rotating the supra-structure element while the extension is inserted into the cylindrical cavity of the implant.
