Patent ID: 7729794

Claim:
A CAD/CAM method for designing a connector between one first and one second element of a dental restoration, where for generating data required for the production of the connector, the connector is designed comprising 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 (γ 0 , γ 4 ) on the first model and the second model, respectively, the edge curves being defined by the origins of surface normal vectors of the models, which satisfy boundary conditions relative to the connecting line; computing offset curves (γ 1 , γ 3 ) on the first model and the second model, respectively, from the edge curves; and connecting the edge curves and the offset curves of the first model and the second model, and computing the connector on the basis of the path of the connection between the curves.
