Patent

CA 2601488

The invention relates to 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 procedure steps: - 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 (.gamma.0, .gamma.4) 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 (.gamma.1, .gamma.3) 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.
