Abstract: A method produces a three-dimensional computer model of an abutment for a tooth implant by a computer, and the abutment has a base, a connecting structure, a platform surface of coronal appearance, and a screw channel. The method includes: providing a three-dimensional representation of a jaw of the patient to be read by the computer, choosing a definition of a preparation margin depending upon the patient's individual gum line, defining a three-dimensional geometry of the abutment above the preparation margin by an operator of the computer or by an algorithm, defining an emergence profile of the abutment by an operator of the computer or by an algorithm, and providing the three-dimensional computer model by the computer. A plate-like design of the platform surface is provided below the preparation margin for the three-dimensional geometry of the platform.

Abstract: A top piece for a corresponding pin-shaped dental implant with a platform, which features a first platform surface and a second platform surface, a retention pin placed onto the first platform surface, for mounting of a mesostructure, a connecting pin for connecting the platform with a blind bore of a pin-shaped dental implant corresponding to the connecting pin, while in a first version, an edge of the platform is bulged in a direction oriented away from the connection pin, and in a second version, a diameter of the platform is large enough, at least in a part of a total angular area that, where the top piece is connected to the corresponding pin-shaped dental implant, in a view from above onto the second platform surface, the platform protrudes over the corresponding pin-shaped dental implant.
