A collaborative approach, incorporating a server for data transmission, security verification, and authentication verification, is implemented between a dental office and a dental laboratory to fabricate a designed dental restoration. A scanner is used in a dental office to take a scan of a patient's mouth. The dental laboratory designs the dental restoration with specialized design software taking into account the scan of the mouth as well as a prescription from the dental office. The parameters defining the designed dental restoration are contained in a design file. The design file is used to create milling specifications defining instructions for milling the designed dental restoration. The materials for the dental restoration are loaded into a mill, where the dental restoration is fabricated in accordance with the milling specifications. Security verification ensures authorized materials are used, and authentication verification ensures authorized materials and processes are used.
