1. A method of determining a dental record of a dental patient's teeth in a computer system comprising the steps of: (a) imaging a patient's teeth so as to produce at least one two dimensional image of the patient's teeth; (b) visually superimposing an initial 3-dimensional computer graphic model of a set of teeth having independently manipulable teeth objects onto said two dimensional image; (c) interactively adjusting at least one of the position, orientation or scaled size of said manipulable teeth objects so that they are aligned with said two dimensional image; and (d) storing the adjusted computer graphic model of said set of teeth as said dental record.
