Abstract
Computer-implemented method for digitally designing a dental restoration for a rest tooth, wherein the rest tooth is described by data of the rest tooth and wherein a tooth template is described by data of the tooth template, by means of an Laplacian surface deformation to deform the tooth template towards the surface of the rest tooth, wherein the method uses, for the Laplacian surface deformation, an angle weighting function depending on: the angle between the normal direction of a target on the surface of the rest tooth or the normal direction of a handle on the tooth template; and the direction of a line connecting the target and the handle; wherein the angle weighting function is used to weight the handle for deforming the tooth template towards the rest tooth. Further, the invention is related to a computer-readable medium having stored thereon instructions, which when executed by a processor, are adapted to perform the method steps of the inventive computer-implemented method.
