Abstract: A system is disclosed for manufacturing a dental workpiece. The system may have a subtractive machine configured to manufacture a base of a dental device from a material blank, and an additive machine configured to manufacture a top of the dental device by adding material onto a surface of the base. The system may also have a controller in communication with the subtractive machine and the additive machine. The controller may be programmed to receive digital data corresponding to a mouth of a particular patient, and to control operation of the subtractive machine to customize the base based on the digital data.

Abstract: A workpiece is disclosed for use in making a dental device. The workpiece may have a ring-shaped frame, and a base form of the dental device additively manufactured inside the ring-shaped frame. The workpiece may also have at least one connector extending between the base form and the ring-shaped frame.

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, 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.

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.
