Computer-implemented method for digitally designing a dental restoration and a computer-readable medium

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, the method comprising automatically deforming the tooth template by means of Laplacian surface deformation such that a prepared part of the rest tooth is covered by a portion of the tooth template, wherein the Laplacian surface deformation comprises automatically generating a line which is going through a point, such as a vertex or a point inside a polygonal of a mesh, on the surface of the rest tooth or the tooth template and which is directed along the normal direction at said point; when the line intersects with the tooth template and with the surface of the rest tooth, automatically choosing the intersection point of the line with the tooth template as handle and the intersection point with the surface of the rest tooth as target; and automatically deforming the tooth template. 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.
