A procedure for fabricating an individual abutment for a dental prosthesis for an implant anchored in an area of the jaw with an implant attachment running on the abutment side, using a working model molded by the jaw area equipped with the implant. The sulcus area of the gum uncovered above the implant and shaped by a sulcus-former extending from the implant attachment is reproduced in the working model. The abutment has a sulcus section running within the sulcus area and an adjoining head section to admit a part of a dental prosthesis. The sulcus area of the working model having an auxiliary implant attachment corresponding to the implant attachment is measured, and a sulcus section model determined with a circumferential surface and a de-facto sulcus line limiting it on the implant side.

Method for fabricating an abutment

A method for designing a connector between a first and a second element of a dental restoration, such as a connector between coping and coping, or coping and pontic, or pontic and pontic of a bridge, which is characterized by the steps of computing a (first) model of the first element and a (second) model of the second element, defining a connecting straight line between the first model and the second model, computing edge curves (&#x3b3;) on the first model and the second model, whereby the edge curves are defined by origins of surface normal vectors of the models, which satisfy boundary conditions relative to the connecting line, computing offset curves (&#x3b3;) on the first model and the second model from the first edge curves, and connecting the first edge curves and the offset curves of the first model and of the second model and computing the connector on the basis of the course of the connection between the curves.
