What is claimed is: 1. A method for producing a physical dental arch model based on a three-dimensional (3D) digital dental arch model, comprising: smoothening the digital dental arch model to make the digital dental arch model suitable for CNC based manufacturing; segmenting the digital dental arc
What is claimed is: 1. A method for producing a physical dental arch model based on a three-dimensional (3D) digital dental arch model, comprising: smoothening the digital dental arch model to make the digital dental arch model suitable for CNC based manufacturing; segmenting the digital dental arch model into at least two manufacturable digital components; producing manufacturable physical components using Computer Numerical Control (CNC) based manufacturing in accordance with the manufacturable digital components; and assembling the manufacturable physical components to form the physical dental arch model. 2. The method of claim 1, further comprising: determining if the smoothened digital dental arch model satisfies one or more predetermine criteria for CNC based manufacturing. 3. The method of claim 2, further comprising running a CNC simulator to determine if the smoothened digital dental arch model satisfies one or more predetermine criteria for CNC based manufacturing. 4. The method of claim 1, wherein smoothening the digital dental arch model includes removing sharp gaps and divots in the teeth arch in the digital dental arch model. 5. The method of claim 1, wherein the manufacturable digital components include a portion of a tooth, a whole tooth, a plurality of teeth, or a complete teeth arch. 6. The method of claim 1, wherein the manufacturable digital components and the manufacturable physical components include features that permit the manufacturable physical components to be assembled into the physical dental arch model. 7. The method of claim 1, wherein the features include one or more of a pin, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or an attachable feature. 8. The method of claim 1, further comprising attaching or plugging the manufacturable physical components into each other to form the physical dental arch model. 9. The method of claim 1, wherein the CNC based manufacturing includes milling, stereolithography, laser machining, and molding. 10. The method of claim 1, wherein the physical dental arch model comprises a material selected from the group consisting of polymers, urethane, epoxy, plastics, plaster, stone, clay, acrylic, metals, wood, paper, ceramics, and porcelain. 11. The method of claim 1, further comprising: obtaining a cast for a teeth arch from a patient; and scanning the cast to obtain the digital data for the digital dental arch model. 12. The method of claim 1, further comprising: generating a digital model for a base compatible with the digital dental arch model; and producing the base that can be assembled with the manufacturable physical components. 13. The method of claim 12, wherein the base comprises one or more features to assist the assembling with the manufacturable physical components, said features comprising one or more of a pin, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or attachable feature. 14. The method of claim 12, further comprising attaching or plugging the manufacturable physical components into the base to form the physical dental arch model over the base. 15. The method of claim 12, further comprising: producing the physical base using CNC based manufacturing. 16. A system for producing a physical dental arch model based on a three-dimensional (3D) digital dental arch model, comprising: a computer configured to smoothen a digital dental arch model to make the digital dental arch model suitable for Computer Numerical Control (CNC) based manufacturing, the computer further configured to segment the digital dental arch model into at least two manufacturable digital components and to provide CNC information for manufacturing the at least two manufacturable digital components; and a manufacturing machine receiving the CNC information, wherein the manufacturing machine is configured to produce manufacturable physical components using CNC based manufacturing in accordance with the CNC information, wherein the manufacturable physical components are configured to be assembled into a physical dental arch model. 17. The system of claim 16, wherein the computer is further configured to determine if the smoothened digital dental arch model satisfies one or more predetermined criteria for CNC based manufacturing. 18. The system of claim 17, wherein the computer comprises a CNC simulator that determines if the smoothened digital dental arch model satisfies one or more predetermine criteria for CNC based manufacturing. 19. The system of claim 16, wherein the computer is configured to remove one or more sharp gaps and divots in a teeth arch in the digital dental arch model. 20. The system of claim 16, wherein the manufacturable digital components include a portion of a tooth, a whole tooth, a plurality of teeth, or a complete teeth arch. 21. The system of claim 16, wherein the manufacturable digital components and the manufacturable physical components include features that permit the manufacturable physical components to be assembled into the physical dental arch model, including one or more of a pin, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or an attachable feature. 22. The system of claim 16, wherein the manufacturing machine is configured to perform one or more of milling, stereolithography, laser machining, and molding. 23. The system of claim 16, wherein the physical dental arch model comprises a material selected from the group consisting of polymers, urethane, epoxy, plastics, plaster, stone, clay, acrylic, metals, wood, paper, ceramics, and porcelain. 24. The system of claim 16, wherein the computer is further configured to generate a digital model for a base compatible with the digital dental arch model, wherein the base comprises one or more features to facilitate assembling with the manufacturable physical components, said features comprising one or more of a pin, a notch, a protrusion, a hole, an interlocking mechanism, a jig, and a pluggable or attachable feature. 25.
