Method and system for dental planning and production
A method and system useful for planning a dental restorative procedure of a patient and for producing at least one dental restoration or product related thereto to be used in the dental restorative procedure are disclosed. Input data from different sources, e.g. 3D data from a CT scan of a patient with a dental impression tray including a previously prepared dental impression of the patient in the patient's mouth, is matched with data from a high resolution 3D scan of the same dental impression. The resulting data is for instance matched by fiducial markers arranged at the dental impression tray.
