Computer-implemented method for digitally designing a dental restoration

The present invention relates to a 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, wherein the method comprises the step of: 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; obtaining axis data defining an axis; based on the obtained axis data, automatically generating a line going through a point on the surface of the rest tooth or the tooth template, wherein the line orthogonally intersects the axis; and 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.
